Description

Power supply method and related device

Technical Field

Background

In countries or regions with poor power grid quality, telecom operators generally adopt a hybrid power supply mode of 'commercial power, storage battery and oil engine' to supply power to base station equipment. The 'storage battery + oil engine' is used as a standby power scheme, and when the mains supply is powered off, the service of the station can be guaranteed not to be interrupted.

However, under the electricity standby scheme of "storage battery + oil engine", the maintenance labor cost of the oil engine hybrid power supply station is high, the oil cost is high, the reliability of the oil engine is poor, the timeliness requirements for repairing and refueling the oil engine are high, the highly-polluted oil hybrid scheme has a large influence on the surrounding environment of the station, and so on.

Under the backup scheme of the storage battery, the power supply capacity of the storage battery is generally planned according to the historical single maximum power failure duration of a station, and when the mains supply fails, the station operates according to the lossless operation load. If the historical single maximum power failure duration is longer, more batteries need to be purchased, and the corresponding equipment transportation cost, occupied land, auxiliary materials and the like are increased along with the increase of the energy configuration quantity of the station, so that the Return On Investment (ROI) is longer, and the investment positivity of a telecom operator is reduced.

Detailed Description

The embodiment of the application provides a power supply method and a related device, which are used for enabling a station to operate when a mains supply fails so as to prolong the operation time of the station.

Embodiments of the present application are described below with reference to the accompanying drawings.

The terms "first," "second," and the like in the description and in the claims of the present application and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and are merely descriptive of the manner in which objects of the same nature are distinguished in the embodiments of the application. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of elements is not necessarily limited to those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

For example, as shown in fig. 1-1, the power supply system is a schematic structural diagram of a power supply system of "commercial power + storage battery + oil engine", and the power supply system may include commercial power, an oil engine, an AC Transfer Switch (ATS), a monitoring unit, a storage battery, a communication base station, and an air conditioner, where the ATS is connected to the commercial power and the oil engine and supplies Alternating Current (AC) to the air conditioner and the monitoring unit. The storage battery is used for supplying Direct Current (DC) to the monitoring unit and the communication base station.

Please refer to fig. 1-2, which are schematic structural diagrams illustrating a power supply system according to an embodiment of the present disclosure. The embodiment of the present application provides a power supply system 100, which includes a control device 110, a station 120, and a power backup device 130. It should be noted that, the station 120 in this application may be a station in a standby power scheme of "commercial power + storage battery + oil engine" that is modified to a standby power scheme of "commercial power + storage battery".

The control device 110 is configured to obtain the current electric quantity of the standby power device 130 in real time when the utility power is off, and enable the station 120 to operate according to the target load if the current electric quantity is not enough to allow the station 120 to operate to the target time point according to the target load. It should be noted that the target time point is a time point when the target power outage duration ends from the mains power outage, and the power consumption per unit duration of the target load is smaller than the power consumption per unit duration of the lossless operation load.

It should be noted that the commercial power, which we term power frequency Alternating Current (AC), is characterized by three common quantities of alternating current: voltage, current, frequency. The power frequency of the common alternating current in all countries in the world is 50 hertz (Hz) and 60Hz, and the distribution of the civil alternating current is different from 100 volts (V) to 380V. The machine room generally introduces three-phase 380V,50HZ commercial power as a power supply, but a power supply rectification module of the equipment uses single-phase 220V voltage. Generally, the commercial power is provided by a municipal power grid and is not in the management range of operators. The station 120 is configured to operate according to a target load under the enable of the control device 110 when the utility power fails. And the standby power equipment 130 is used for supplying power to the station 120 when the mains supply is powered off.

In some possible implementations, the control device 110 is further configured to enable the station 120 to operate at the lossless operating load if the current amount of power is sufficient for the station 120 to operate at the target load to the target time point. The station 120 is also configured to operate at a lossless operating load, enabled by the control device 110.

In some possible implementations, the control device 110 is further configured to obtain real-time power of the station 120 when the utility power is supplied, determine a charging rate for the power backup device 130 according to the real-time power, and charge the power backup device in real time by using the charging rate.

In some possible implementations, the control device 110 may be a server. The servers may vary widely in configuration or performance and may include one or more Central Processing Units (CPUs), such as one or more processors, and memory, one or more storage media (e.g., one or more mass storage devices) that store applications or data. The memory and storage medium may be, among other things, transitory or persistent storage. The program stored on the storage medium may include one or more modules (not shown), each of which may include a series of instruction operations for the server. Still further, the central processor may be configured to communicate with the storage medium and execute a series of instruction operations in the storage medium on the server.

In the embodiment of the present application, the control device 110 may include an alternating current transfer switch (ATS), a monitoring unit, a network manager, and the like. The ATS is a control device for switching between the commercial power and the standby power device 130. The monitoring unit serves as a collector of environmental information data of the station 120, and is used for collecting no-mains alarms and analyzing a power failure model of the station 120. The monitoring unit can also be used as the brain of the power supply system to control the start-stop and fast charging functions of the standby power equipment 130. The network manager may manage various devices in the site 120, and carry configuration of various parameters and monitoring of Key Performance Indicators (KPIs) of the site 120.

Station 120 may be a communication station such as a base station. The base station is a public mobile communication base station, is an interface device for accessing the mobile terminal to the internet, is also a form of radio station, and is used as a mobile communication switching center to realize information transmission between the base station and the mobile terminal in a certain radio coverage area. The construction of base stations is an important part of telecommunication operators investment, and is generally carried out around the factors of coverage, call quality, investment benefit, difficult construction, convenient maintenance and the like.

In some possible implementations, the station 120 may be a master device in a base station, and provide various types of access services for the mobile terminal, such as access services of a second Generation wireless communication technology specification (2-Generation wireless telephone technology, 2G), a third Generation wireless communication technology specification (3-Generation wireless telephone technology, 3G), a fourth Generation wireless communication technology specification (4-Generation wireless telephone technology, 4G), and a fifth Generation wireless communication technology specification (5-Generation wireless telephone technology, 5G), so that the base station can provide signal coverage in a peripheral area.

The power backup device 130 includes a battery, and the battery is used to supply power to the station 120 when the utility power fails, and can charge the power backup device 130 to store energy when the utility power is normal.

In some possible implementations, the power supply system 100 also includes other companion devices. For example, other dc power supply devices, such as transmission devices in a machine room, home wide devices, etc., have higher priority for service provisioning. Taking the transmission device as an example, the transmission device has a trunk and a sub-trunk, and if the trunk node of the transmission device is powered off due to insufficient power supply, a large area of network disconnection will be caused, and the influence is very serious.

Under the backup scheme of the storage battery, the power supply capacity of the storage battery is generally planned according to the historical single maximum power failure duration of a station. If the historical single maximum power failure duration is longer, more batteries need to be purchased, and the corresponding equipment transportation cost, occupied land, auxiliary materials and the like are increased along with the increase of the energy configuration quantity of the station, so that the Return On Investment (ROI) is longer, and the investment positivity of a telecom operator is reduced.

Take a site configured for 3-frequency (2G/3G/4G) + 1-frequency (5G) service as an example. A typical average power consumption of such a site is 5 kw, and if a maximum single outage duration of 5 hours is used as a site power reserve requirement, a battery of about 750 ampere hours (Ah) is required. If the maximum single power failure time is 7 hours, the battery needs about 1050 Ah. The ROI is far larger than the ROI expected by telecom operators (2 years) no matter 5 hours or 7 hours, so that the positivity of investment of the telecom operators is reduced.

In conclusion, the station power supply planning is carried out by adopting the historical single maximum power failure time length, the method is too simple and violent, the historical single power failure time length is not subjected to subsection proportion statistics, and the method is not in linkage negotiation with the station, so that the applicability is poor, the application area is narrow, the ROI of the client investment income is long, and the enthusiasm of the telecommunication operator investment is low.

The power supply method comprises the steps of acquiring the current electric quantity of standby power equipment in real time when the mains supply is powered off, enabling a station to operate according to a target load if the current electric quantity is not enough to enable the station to operate to the target time point according to the target load, wherein the target time point is the time point when the target power-off time length is finished from the mains supply power-off, and the power consumption of the target load in unit time length is smaller than that of a lossless operation load, so that the operation time length of the station is prolonged, and the service loss degree of the station is within the acceptable range of users. Therefore, the required power capacity of the storage battery is smaller, the ROI is reduced, and the investment positivity of a telecom operator is improved.

To this end, please refer to fig. 2-1, which is a power supply method provided by the present application, including:

201. and determining the maximum standby power quantity of the standby power equipment according to the ROI.

In the embodiment of the present application, the ROI is the ROI desired by the user, and the user can input the ROI according to the user's own desire. In some possible implementations, the user may calculate the ROI according to a preset algorithm, or may input the ROI only according to the desire, which is not limited herein. For example, the ROI is 2 years, 3 years or 5 years. In the embodiment of the present application, the maximum power backup capacity is the power backup capacity of the power backup device required to satisfy the ROI.

Optionally, in some possible implementations, according to the ROI, the maximum power reserve may be determined through the following steps 2011-2014:

2011. and receiving a target return on investment period ROI input by a user.

For example, 2 years. The user may be a telecommunications carrier or other type of user, which is not limited herein.

2012. The total investment for purchasing batteries is calculated from the ROI.

In some possible implementations, ROI = deoiler investment site energy conversion Capex cost ÷ (annual oil mixing site Opex cost-post-deoiler site electricity cost consumed annually).

Wherein, the annual oil mixing site Opex cost = power maintenance cost + battery maintenance cost + other + oil engine cost + commercial power;

the power supply maintenance cost = routine maintenance, material replacement and abnormal overhaul, which are fixed values;

the maintenance cost = routine maintenance, material replacement and abnormal overhaul, which are fixed values;

other = routine maintenance + material replacement + abnormal overhaul, all of which are fixed values;

oil engine charge = oil charge + refueling cost + routine maintenance + material replacement + abnormal maintenance;

oil cost = oil consumption per day, L/D oil cost, $ 365 $ (1 + theft rate); (L for oil consumption, D for 1 day)

Oil consumption per day, L/D = degree electricity oil consumption, L/kWh (table look-up) oil engine electricity per day, kWh; (kWh is kilowatt-hour)

It should be noted that the fuel consumption per watt hour, L/kwh (look-up table) can be obtained by looking up a table according to "actual load rate,% = (load average power, kW + battery charge average current 53.5/1000)/0.9/oil engine capacity (kVA), 0.9 is ac-dc efficiency"; (kVA is kilovolt-ampere)

Battery stock charge average current = charge rate and battery stock capacity;

per day of electric quantity of the oil engine, kWh = per running time of the oil engine/d + average per running time, h + per h generated energy, kWh;

generating capacity per h, kWh = actual load factor,% oil engine capacity, kVA 0.8;

average operation time per time, h = average operation time of the oil engine per day, and h/operation times/d of the oil engine;

refueling cost = oil cost 0.1;

routine maintenance =50 maintenance count;

number of maintenance = annual run time/500;

annual operating time = average oil engine operating duration per day, h 365;

material change =200 × maintenance times;

abnormal overhaul =50;

remarking: the theft rate is 10% of the empirical value; and the L/kwh (lookup table) can be used for calculating the load ratio according to the total load of the station, other equipment and battery charging and the capacity of the oiling machine, and searching the oil consumption data of the oiling machine under different load ratios.

The commercial power cost = electric charge + routine maintenance cost + material replacement cost + abnormal overhaul cost;

electric charge = (24-average oil engine operating time per day, h) (load average power, kW/stock power efficiency) 365 electric charge, $/kWh;

the material replacement cost and the abnormal overhaul cost are fixed values;

the annual electricity consumption of the site behind the deoiler is the electricity consumption of the load operation of the site;

the investment cost of the oil remover for site energy source transformation Capex cost refers to the cost of site power supply transformation, wherein the cost comprises the power supply transformation cost of a site and the energy storage transformation cost of the site, and the two costs need to be estimated through a power failure model of the site and the load average power consumption of the site.

From the above equation, it can be deduced that: the degreaser investment site energy modification Capex cost = ROI × Opex cost of oil mixing station annually-electricity cost consumed by site after degreaser annually). Then, the user can calculate the energy reformation Capex cost of the investment site of the oil remover according to the expected ROI, namely the total investment of purchasing the battery.

2013. And determining the number of the batteries according to the total input and the price of the single battery in the standby equipment.

In some possible implementations, the total investment may be divided by the price of a single battery in the backup device to obtain the number of batteries, i.e.: total investment ÷ cost of individual cells/100 Ah = total number of cells.

2014. And determining the maximum standby power electric quantity according to the number of the batteries and the electric quantity of the single battery in the standby power equipment.

In some possible implementations, the number of batteries may be multiplied by the electric quantity of a single battery in the power backup device to obtain the maximum power backup electric quantity, that is: the total number of battery blocks × 100Ah = maximum standby power amount.

In the embodiment of the present application, through the steps 2011-2014, the maximum power backup electric quantity of the power backup device can be determined according to the ROI expected by the user. In some possible implementations, the maximum power backup capacity of the power backup device may also be determined by other manners, which are not limited herein.

202. And determining the target power failure duration of the station.

It should be noted that if the station standby power planning is performed by using the historical single maximum power outage duration, the planning is too simple and violent, the historical single power outage duration is not subjected to the segmental proportion statistics, and the planning is not in linkage negotiation with the station, so that the ROI of the user is relatively long, and the investment enthusiasm of the telecom operator is low. Therefore, in the embodiment of the application, the reasonable target power failure time length can be determined according to the actual situation.

Optionally, in this embodiment of the present application, the target outage duration of the station may be determined through the following steps:

2021. and acquiring historical power failure data of the station.

It should be noted that, in a scene with historical power failure alarms, historical single power failure information alarms within a certain period, for example, historical single power failure information alarms within 1 year, may be acquired from a user. Then, according to the historical single power failure information alarm, the power failure alarm clearing time can be used to subtract the alarm occurrence time, and the single power failure time length can be obtained.

The following actual network case (3 power failure alarm information of a certain operator station):

site name	Time of alarm occurrence	Time of alarm clearing	Duration of single power failure (hours)
				a	2020/12/8 15:27	2020/12/8 17:32	2.08
b	2020/12/8 17:47	2020/12/8 18:22	0.58
				c	2020/12/8 18:04	2020/12/8 21:26	3.37

2022. And determining the cumulative distribution of the power outage duration according to historical power outage data.

In the embodiment of the present application, according to the historical outage data of the site obtained in step 2021, as shown in fig. 2-2, a Cumulative Distribution Function (CDF) graph of the single outage duration may be obtained.

2023. A target probability input by a user is received.

It should be noted that the historical single blackout durations of different stations are different, and the probability of the over-long blackout is smaller. Therefore, the standby power configuration of the station can be carried out according to the approximate power outage duration, for example, the time length of 90% of the power outage probability can meet the power supply requirement of most intermittent power outages of the station, and the 90% probability of service is lossless. In some possible implementations, the user may enter 80%, or 95%, or other probabilities, without limitation.

2024. And determining the target power failure duration according to the target probability and the cumulative distribution of the power failure durations.

For example, as shown in fig. 2-2, if the target probability is 90%, the target power-off duration may be determined to be 4 hours; if the target probability is 95%, the target power failure duration can be determined to be 7 hours. Obviously, the higher the target probability, the longer the outage duration, the higher the maximum powered electricity, and the longer the ROI. For this reason, a target probability of 100% is not required, and a more reasonable target probability, e.g., 90%, may be set.

In the embodiment of the present application, the target outage duration of the station can be determined through the above steps 2021 to 2024. In some possible implementation manners, the target outage duration of the station may also be determined in other manners, which are not limited herein.

203. A target load for the station is determined.

In the embodiment of the present application, the load refers to various communication systems carried by a station, for example, 2G, 3G, 4G, 5G, and the like. The power consumption per unit time of the target load is less than the power consumption per unit time of the lossless operation load, the lossless operation load includes all communication systems of the station, including 2G, 3G, 4G and 5G, and the target load may include a part of the lossless operation load, for example, only 2G and 3G are reserved.

It should be noted that, in some possible implementations, the target load includes a load of a reserved cell, that is, a coverage cell that is preferentially guaranteed by a telecommunication operator when a mains power fails. The lossless operation load comprises the load of the unreserved cell, and the low-priority capacity layer cell is guaranteed for a telecom operator when the mains supply is powered off.

Optionally, in some possible implementations, from the ROI, the target load of the station may be determined by the following steps 2031-2032:

2031. unnecessary loads of the stations are determined.

In the embodiment of the present application, the unnecessary load may be a load of one or more of a 5G system, a 4G system, and a 3G system. For example, the unnecessary load is 5G system.

2032. And determining the target load as other loads except unnecessary loads in the lossless operation load.

For example, if the lossless operation loads are 2G, 3G, 4G, and 5G and the unnecessary loads are 5G, the target loads are 2G, 3G, and 4G. If the lossless operation loads are 2G, 3G, 4G, and 5G, and the unnecessary loads are 4G and 5G, the target loads are 2G and 3G.

For example, in a network of an actual telecommunications carrier, there are various systems, and each system has cells with different frequency bands, and the telecommunications carrier may perform priority guarantee selection of different cells according to a situation of a site, such as service priority or voice priority. For example, the user would use the 800M low frequency coverage of 4G as the backing cell for data service, and use the 900M coverage of 2G as the backing cell for voice service, and it is algorithmically necessary to reserve enough power for the two backing cells in advance, that is, the target load includes the loads of the two backing cells.

In other unreserved cells that can be turned off, even if the cells are turned off, the module still has a low static load, which consumes power all the time, so that enough power needs to be reserved for this purpose, i.e., the target load includes the static load of the unreserved cells.

It should be noted that, in addition to the main device, the station may also have other devices, such as a transmission, a home broadband, and a baseband processing unit (BBU), and also needs to reserve enough power for this purpose, that is, the target load includes the load of the transmission, the home broadband, and the BBU.

It should be noted that the power of the reserved cell has different values with the level of the service, and there is a risk in taking the average value, so the power under full service is obtained by considering the module configuration power, i.e. the power of the module transmission port, and combining the conversion efficiency, and this power is taken as the power of the reserved cell, i.e. the power of the target load. If a module emitting port is configured with power of 10 watts and has 2 ports, the power can be converted into 2 × 10/0.35, and 0.35 is the conversion efficiency of most modules. It should be noted that, for static load, it can be estimated according to the capability of the product. It should be noted that, for the power of Other devices (such as transmission, home broadband, and BBU), the calculation method is Other power = site level real-time total power — host device real-time power.

In the embodiment of the present application, the target load of the station can be determined through steps 2031 to 2032. In some possible implementations, the target load of the station may also be determined by other means, which is not limited herein.

204. And determining whether the station is a deoilable station or not according to the target power failure duration, the target load and the maximum standby power quantity.

It should be noted that, if the maximum power reserve capacity of a station can be operated for the target power outage duration, it indicates that the station does not need an oil engine, that is, the station capable of removing oil. In the embodiment of the present application, if a station operates according to a target load, if the maximum power reserve capacity of the station can maintain a target outage duration, the station is a deoilable station.

Optionally, in some possible implementations, according to the target outage duration, the target load and the maximum power reserve capacity, it may be determined whether the station is a deoilable station through the following steps 2041 to 2042:

2041. and determining the target power supply quantity according to the target power failure duration and the target load.

In some possible implementations, the target power outage duration may be multiplied by the target load to obtain the target power supply capacity. Note that the target power supply amount is the minimum required amount of power.

2042. And if the target power supply electric quantity is not larger than the maximum standby power supply electric quantity, determining the station as the oil removal station.

In the embodiment of the application, after the target power supply electric quantity is determined, whether the target power supply electric quantity is not larger than the maximum standby power electric quantity is judged, if the target power supply electric quantity is not larger than the maximum standby power electric quantity, the maximum standby power electric quantity is enough to enable a station to operate for the target power outage duration according to the target load, and then the station is determined to be the oil removal station. Otherwise, if the target power supply capacity is larger than the maximum standby power capacity, it is indicated that the maximum standby power capacity is not enough to enable the station to operate for the target power failure duration according to the target load, and then the station is determined to be a non-deoilable station. The website capable of being deoiled in the network is accurately identified through the ROI of the website by the user, and the blind investment of the user is avoided.

The following examples are given.

For example, as shown in fig. 2-3, when the power failure occurs at point 0, the upper graph shows that the station operates according to the lossless operation load, where the power (P) of the lossless operation load is P1, and the lower graph shows that the station operates according to the target load, where the power (P) of the target load is P2. As can be seen, the time length of the maximum standby power electric quantity available for the station to operate according to the lossless operation load is t0, that is, P1 is multiplied by t0, so as to obtain the maximum standby power electric quantity. And (4) setting the target power failure time length as t2, calculating the product of P2 and t2 to obtain the target power supply electric quantity. If the target power supply electric quantity is not larger than the maximum standby power supply electric quantity, determining the station as a deoilable station; and if the target power supply electric quantity is larger than the maximum standby power supply electric quantity, determining the station as a non-deoilable station.

Note that t0 is the maximum backup power amount calculated from the ROI in step 201, and the time length obtained by dividing the maximum backup power amount by the power of the lossless operation load is used. t2 is the target blackout duration determined by the target probability and the cumulative distribution of blackout durations in step 202.

It should be noted that, for the oil removal station, that is, if the target power supply capacity is not greater than the maximum power reserve capacity, the maximum power reserve capacity supplies the target power supply capacity for a surplus, the station can operate according to the lossless operation load when power is just cut off (point 0), and then start to operate according to the target load at t 1.

As shown in fig. 2-4, P1 is multiplied by t0 to obtain an area a, i.e., the maximum power reserve capacity; p1 multiplied by t1 obtains the area B, namely the electric quantity of the station operating according to the lossless operation load; and P2 (t 2-t 1) obtains the area C, namely the electric quantity of the station running according to the target load. As long as the sum of the area B and the area C is not more than the area A, namely P1 multiplied by t1+ P2 (t 2-t 1) is less than or equal to P1 multiplied by t0, the mobile terminal can operate according to lossless operation load within the time of t1, and the user experience of the mobile terminal is guaranteed to the maximum extent.

In the embodiment of the present application, the determination that the station is a deoilable station can be realized through the above steps 2041 to 2042. In some possible implementations, the site may be determined to be a deoilable site in other ways, and is not limited herein.

205. When the commercial power is in power failure, the enabling standby power equipment supplies power to the station and operates according to the target power failure duration, the target load and the enabling station.

After the station is determined to be a deoilable station through the foregoing step 204, when the utility power fails, the standby power equipment may be enabled to supply power to the station, and operate according to the target power failure duration, the target load, and the enabled station.

Optionally, in some possible implementation manners, according to the target outage duration, the target load, and the maximum standby power amount, the station may be enabled to operate through the following steps 2051 to 2053:

2051. when the commercial power is cut off, the current electric quantity of the standby power equipment is acquired in real time.

It should be noted that at t0 in fig. 2-3 or fig. 2-4, the current power amount of the power backup device is the maximum power backup power amount, and after t0, the power backup device continuously supplies power to the station, so that the current power amount of the power backup device gradually decreases. In addition, the current power of the backup power equipment is not always the maximum backup power at the time of power failure. For example, there are two power outages that are close in time, and the backup power device discharges a portion at the first power outage. When the commercial power recovers, the standby power equipment is charged, but before the commercial power is fully charged, the power is cut off for the second time, and the electric quantity of the standby power equipment is only one part of the maximum standby power electric quantity.

2052. And determining the target electric quantity according to the target load and the target power failure duration.

In the embodiment of the application, the target electric quantity is electric quantity which allows a station to operate to a target time point according to a target load, wherein the target time point is a time point when the target power failure duration is finished from the power failure of the commercial power.

2053. And if the current electric quantity is larger than the target electric quantity, enabling the station to operate according to the lossless operation load.

In the embodiment of the application, whether the current electric quantity is enough to enable the station to operate to the target time point according to the target load can be judged according to the target electric quantity. If the current electric quantity is larger than the target electric quantity, namely the current electric quantity is enough to enable the station to operate to the target time point according to the target load, the current electric quantity is enough, the station can operate according to the lossless operation load, and the user experience of the mobile terminal is guaranteed.

2054. And if the current electric quantity is not larger than the target electric quantity, enabling the station to operate according to the target load.

If the current electric quantity is not larger than the target electric quantity, namely the current electric quantity is not enough to enable the station to operate to the target time point according to the target load, the current electric quantity is not enough, the station is enabled to operate according to the target load, and the station operation time is guaranteed as much as possible.

For example, in some possible implementations, as shown in fig. 2-5, the above-described steps 2051-2054 may be implemented by the following control flow:

and S0, starting the function.

S1, judging the state of the commercial power.

The mains supply has two states, namely the mains supply is disconnected and the mains supply is normal. If the mains supply is normal, jumping to S2; and if the mains supply is disconnected, jumping to S3. Step S1 may be performed periodically, for example once in 5 minutes or 10 minutes.

And S2, enabling the site to operate according to the lossless operation load.

In the embodiment of the present application, the lossless operation load includes a target load and an unnecessary load, the target load includes a load of the reserved cell, and the unnecessary load includes a load of the unreserved cell. If the unreserved cell (i.e., unnecessary load) has been turned off, then the unreserved cell operation can be resumed. And if the unreserved cell is not switched off, the unreserved cell is allowed to continue to work.

And returning to S1.

And S3, acquiring the current electric quantity of the standby power equipment in real time. (corresponding to step 2051)

And S4, judging whether the current electric quantity is enough to enable the station to operate to a target time point according to the target load. (corresponding to step 2052, and conditions in step 2053 and step 2054)

And if the current electric quantity is enough to enable the station to operate to the target time point according to the target load, operating the step S5, otherwise, operating the step S6. This step S4 may be run periodically once, for example 5 minutes or 10 minutes.

And S5, enabling the site to operate according to the lossless operation load. (corresponding to step 2053)

And S6, enabling the station to operate according to the target load. (corresponding to step 2054)

It should be noted that, as shown in fig. 2 to 6, for the purpose of illustrating an embodiment of wireless energy linkage, the control device for performing the above steps may include an energy monitoring unit and a network manager. The energy monitoring unit reports the current electric quantity of the standby power equipment, including the current electric quantity of the lead-acid battery and the lithium battery, and also reports the state of the mains supply (whether power is off), the total direct current output power of the station and the like, and the current electric quantity is transmitted to a network manager through a baseband processing unit (BBU). The network manager, as a control brain, can combine the configuration list under the BBU, count the module quantity, target load (reserved cell and other device (other) configuration power) to judge, if the current electric quantity is not enough to let the site operate to the target time point according to the target load, the network manager enables the site to operate according to the target load (i.e. turn off the unreserved cell), realize the linkage of wireless energy.

As shown in fig. 2-7, when the utility power is cut off, the enabled standby power equipment supplies power to the station, the current electric quantity is enough to make the station operate to the target time point (t 2) according to the target load, and the enabled station operates to t1 according to the lossless operation load, wherein the lossless operation load comprises 5G@3.5G, 4G@2.6G, 3G@2.1G, 2G@1.8G, 4g @800m, 2g @900m, the static load, the load of BBU and the load of other equipment (other). At t1, the current electric quantity is not enough to make the station operate to the target time point (t 2) according to the target load, so that the station is enabled to operate according to the target load (reserved cell), namely 5G@3.5G, 4G@2.6G, 3G@2.1G and 2G@1.8G (unnecessary load) are turned off, and loads of 4g @800m, 2g @900m, static load, BBU and loads of other devices (other) (target load) are reserved.

In some possible implementations, 5G@3.5G, 4G@2.6G, 3G@2.1G, 2G@1.8G (unnecessary loads) may be turned off in steps without the need to turn off at the same time.

In some feasible implementation modes, in addition, for unexpected overlength power failure caused by unexpected overlength power failure such as current limiting, road repairing and other emergencies, the target power failure duration can be reset, unnecessary loads are turned off during power failure, only the target load is reserved, longer power failure duration is responded, and a battery does not need to be added.

Through the steps 2051-2053, the linkage between the standby power equipment and the station is realized, and when no commercial power is cut off, the load of the station is reduced (from lossless operation load to target load) according to the current electric quantity of the standby power equipment and the target time point, so that the purpose of prolonging the time for which the station can be cut off is achieved, and the probability of service loss of the station is within the acceptable range of customers. Meanwhile, due to the linkage of the standby power equipment and the station, the station energy consumption is reduced by controlling the station service according to the station energy storage condition under the extremely-long power failure condition with small probability, the station can still provide basic service functions in an extremely-long power failure time period, and the problem of accidental extremely-long power failure of the station caused by emergency is solved.

206. When the commercial power supplies power, the standby power equipment is charged in a self-adaptive mode.

In the embodiment of the application, after the mains supply is recovered, the switched-off unnecessary load recovers work, and the access limitation of the service of the unnecessary load in the site is removed. When the commercial power supplies power, the standby power equipment is charged. However, the utility power is required to charge the backup power device and supply power to the station, which causes an excessive power load, which may exceed the power supply capacity of the transformer and the power line at the front end of the power supply of the station, i.e. the utility power supply capacity of the station is insufficient or the cable bearing capacity is insufficient, which causes a high cost for the transformation of the user.

For the power supply capacity of a transformer and a power transmission line at the front end of power supply, the purpose of rectifying and reforming the mains supply in a short time is difficult, and the processes of rectifying and reforming the mains supply, examining and approving and the like need to be carried out. Based on the factor, the embodiment of the application also provides an adaptive quick charging function of the standby power equipment, and under the condition that the capacity of the commercial power is not exceeded, the charging multiplying power of the standby power equipment is adaptively adjusted.

Illustratively, when the commercial power is recovered to be normal, the charging rate of the battery can be dynamically adjusted by combining the power supply capacity of the station, so that the transformation of the power supply capacity of the commercial power is reduced to the maximum extent. The charging coefficient of the standby power equipment is adjusted in a self-adaptive mode according to the commercial power supply capacity, the service load of the station and the maximum charging capacity of the standby power equipment, and the standby power equipment is charged quickly, reliably and safely.

To this end, in some possible implementations, the power backup device may be adaptively charged by the following steps 2061-2063:

2061. and when the commercial power is supplied, acquiring the real-time power of the station.

It should be noted that the control of the adaptive fast charging function can be applied to the following two scenarios:

1. under the condition that the commercial power is normal, the current electric quantity of the standby power equipment is not enough to supply the condition that the station operates for the target power failure time according to the target load;

2. in the case that the capacity (transformer) of the commercial power is small, the required load (the load for the station to operate and the load for charging the standby power equipment) is larger than the capacity of the commercial power, and the impact on the commercial power is large.

For this reason, in the present embodiment, when the mains is powered, the real-time power of the station is first acquired.

2062. And determining the charging multiplying power of the standby power equipment according to the real-time power.

And after the real-time power of the station is obtained, determining the charging multiplying power of the standby power equipment according to the real-time power of the station and the commercial power capacity.

2063. And charging the standby power equipment in real time by using the charging rate.

Under the normal condition of commercial power, the commercial power needs to charge the standby power equipment, but the situation that the power supply energy is limited may exist, so through the linkage with the website, the real-time power of the website is obtained, the charging multiplying power of the standby power equipment is dynamically adjusted, and the impact on front-end equipment, such as commercial power or a cabinet power supply, is avoided.

For example, as shown in fig. 2-8, in some possible implementations, the steps 2061-2063 may be implemented by the following control flow:

and S0, starting functions.

S1, judging the state of the commercial power.

The mains supply has two states, namely, the mains supply is disconnected and the mains supply is normal. If the mains supply is normal, jumping to S3; and if the mains supply is disconnected, jumping to S2. Step S1 may be performed periodically, for example once in 5 minutes or 10 minutes.

And S2, closing the charging function.

And S3, acquiring the real-time power of the station. (corresponding to step 2061)

And S4, calculating the residual capacity according to the real-time power.

In the embodiment of the present application, remaining capacity = capacity value — real-time power of the station.

And S5, determining the charging rate of the standby power equipment according to the residual capacity. (Steps S4 and S5 correspond to step 2062 described above)

In the present embodiment, the charging rate = remaining capacity/voltage of the mains/total capacity of the backup device.

And S6, charging the standby power equipment in real time by using the charging rate. (corresponding to step 2063)

For example, the following table 1 is a charge power table between 00 and 23:

From table 1 above, fig. 2-9 can be obtained, where at 00.
