Description

Power system communication network deployment processing method and device

technical field

The present invention relates to the field of power system communication, in particular to a method and device for deploying and processing a power system communication network.

Background technique

The power communication network is an important technical support means of the power grid, and plays an important role in ensuring the safe operation of the power grid and modern enterprise management. With the rapid advancement of power grid intelligence and enterprise informatization, the power communication network urgently needs to expand Integrating and evolving in the direction of the electric power Internet of Things, it undertakes more arduous and comprehensive support and guarantee tasks.

However, in the prior art, the power communication network is a public network, and there are the following problems:

1. Single fiber coverage mode, lack of hybrid networking applications

At present, the power distribution business in core urban areas mostly uses optical fiber access, and the communication method is relatively simple. Moreover, the optical fiber network has problems such as long construction period and high cost, which cannot meet the full coverage requirements of business terminals. Lack of hybrid networking planning and solutions that can adapt to applications such as mobile operations, and cannot adapt to the extensive access and coverage of large-scale, multi-type ubiquitous terminals.

2. The quality of the wireless public network channel is difficult to guarantee, and there are security risks

1) Although the current wireless public network has been gradually improved in terms of coverage density and signal strength, in areas such as UHV line corridors, the signal coverage and strength still cannot meet the needs of power communication, and there are problems such as data delay and loss.

2) In principle, the capacity of the wireless public network is designed according to the premise of a certain amount of traffic (about 10%-30% of users use). In the event of emergencies such as floods and fires, major conferences, etc., the public network may be paralyzed by a large number of users. The information transmission of power equipment relies too much on the public network, so there must be unreliable factors.

3) After the power terminal business data enters the operator's base station through the wireless public network, the data needs to take a rather long route on the Internet to reach the ICT computer room of the city company where it is located. The power sector lacks management and maintenance authority over communication channels and equipment, and cannot guarantee communication quality.

3. The backbone communication network of prefectures and cities has the following problems

1) Performance degradation of old equipment

In some cities in Qinghai, there are a large proportion of old equipment in the transmission network. Most of the transmission equipment with a long operating life has been discontinued due to outdated versions. It is difficult to purchase spare parts, and there are problems such as low cross-connection capacity, performance degradation, and insufficient slots for low-level equipment. , which greatly limits the carrying capacity of the transmission network, and cannot meet the communication needs of the development of the power grid and the company's operation and management, and brings great hidden dangers to the stable operation of the transmission network.

2) Insufficient backbone ring network bandwidth

With the construction of the main network and distribution network in relevant areas and the development of the new energy industry, the bandwidth of the corresponding power data communication network has been rapidly increased. In addition to the planning and construction of the power wireless private network, the existing optical fiber backbone ring network has Unable to meet the increasing demand for transmission load, the bandwidth capacity is insufficient.

For the above problems, no effective solution has been proposed yet.

Fig. 1 is a flowchart of a power system communication network deployment processing method according to an embodiment of the present invention. As shown in Fig. 1, the method includes the following steps:

Step S102, determine the number and type of terminals in the predetermined area, wherein the terminal is a device that needs to use the power system communication network for data transmission, and the type is divided according to the demand for communication resources, that is, the type is based on the communication resources. The demand is divided;

The above-mentioned terminal includes a communication module, which is used to cooperate with the uplink and downlink data transmitted between the base station and the terminal. It should be noted that since the terminal is a device that needs to use the power system communication network for data transmission, the physical and protocol specifications of its communication module are required to comply with the State Grid Regulations. In practical applications, it can be directly embedded in the corresponding terminal, reducing Implementation complexity.

During the implementation process, the base stations in the predetermined area can be deployed according to the number and types of terminals. In order to make the deployed base stations more reasonable and meet the data transmission needs of each service terminal, the predetermined area can be divided into several sub-regions. In the predetermined area, base stations corresponding to the area are deployed according to the number and types of terminals in the sub-predetermined area. It should be noted that the above base station deployment solution includes but not limited to the number of base stations and the geographical location of each base station.

After completing the deployment plan of the base station, it is necessary to further combine the required capacity of the communication network to obtain the deployment plan of the core network. Wherein, the deployment plan of the core network includes, but is not limited to, the geographic address of the core network element to be deployed, the performance of the core network element to be deployed, and the quantity of the core network element to be deployed.

The above method builds a wireless private network applied to the power system. In the application, factors such as the predetermined area, the division of the power supply area of the predetermined area, and the status quo of the terminal communication access network can be fully considered, and the wireless private network is constructed based on the terminal, so that the wireless private network meets Power business development needs.

Through the above steps, it is possible to determine the number and type of terminals in the predetermined area, wherein the terminals are devices that need to use the power system communication network for data transmission, and the types are divided according to the demand for communication resources; according to the number of terminals and type determine the deployment plan of the base station in the predetermined area, wherein the deployment plan of the base station includes: the number of base stations and the geographical location of each base station; determine the deployment plan of the core network according to the deployment plan of the base station and the required capacity of the communication network, wherein , the deployment plan of the core network includes: the geographic address of the core network element to be deployed, the performance of the core network element to be deployed, and the number of the core network element to be deployed, and the corresponding base station is determined by the number and type of terminals The deployment plan of the core network is combined with the demand capacity of the communication network to obtain the deployment plan of the core network, which achieves the purpose of building a communication network of the power system, thereby realizing the technology of improving the safety and reliability of the communication network of the power system, multiple functions in one network, and high quality and efficiency The effect, and then solve the technical problem that the power system communication network in the related technology cannot meet the development needs of the power business.

Optionally, determining the number and types of terminals in the predetermined area includes: obtaining communication requirements of devices in the power system in the predetermined area; and determining the number and types of terminals according to the communication requirements.

It should be noted that the above-mentioned terminals are used to meet different service requirements, that is, communication requirements of devices in the power system, and can be specifically divided into basic services and extended services.

In the basic business, for example, the distribution automation terminal realizes the automatic monitoring and control of the operation of the distribution network. The distribution automation mainly covers distribution network equipment such as switch stations, ring network units, and pole-mounted switches, and the communication rate is not lower than 2.4kbps . The power consumption information collection terminal is to collect, process and monitor the power consumption information of power users in real time. The communication rate of power consumption data collection business is not lower than 1.05kbps according to different users. For load control instructions, the transmission rate is not lower than 2.5kbps . Distributed power supply terminal is to realize the automation of distributed power supply operation monitoring and control, and the communication rate requirement is not lower than 4kbps. The precise load control terminal is a system protection network with interruptible load as the specific control object. According to different control requirements, it is divided into a millisecond-level control system for fast load control and a second-level and minute-level control system. The communication rate requires millisecond-level control. No less than 22.4kbps, second and minute level control no less than 48.1kbps.

In the expansion business, the electric vehicle charging and swapping station terminals generally include various centralized charging stations, charging piles, shore power and system master stations, etc., which mainly realize gateway meters and automatic transmission control units (Transmission Control Unit, referred to as TCU) It is connected with the main station of the electricity consumption information collection system and the Internet of Vehicles platform, and the transmission rate is not lower than 8kbps. The power transmission and transformation status monitoring terminal is used for real-time monitoring of information such as temperature, weather, and on-site environment of power transmission and transformation equipment and lines. According to relevant power transmission and transformation standards, the transmission rate of a single video access point for power transmission and transformation status monitoring services shall not be lower than 2Mbps. The comprehensive monitoring terminal of the power distribution station is used for power distribution equipment/environmental state monitoring for power distribution state maintenance, mainly including station room (ring network cabinet, power distribution room, etc.) temperature measurement, live detection, etc., and a small amount of power distribution line state monitoring . The transmission rate of data collected by a single terminal should be ≥20kbps; when image services are included, the transmission communication requirements should be ≥256kbps; when video services are included, the transmission communication requirements should be ≥2048kbps. The environmental monitoring terminal of the opening and closing station monitors the working environment of the opening and closing station in real time through the application of collection and transmission technology. The transmission rate is not lower than 20kbps, the image transmission rate is not lower than 256kbps, and the video transmission rate is not lower than 2Mbps. The mobile operation business terminal includes functions such as on-site patrol operation, patrol check-in and patrol monitoring. The transmission rate requirements are 8-64kbps for voice services, 384kbps-2Mbps for video services, and 64kbps-2Mbps for data services. The warehouse management terminal establishes an intelligent management system covering the entire warehouse through the application of wireless private network, robot, radio frequency and other technologies. According to different business transmission rates, the range is: voice business 8-64kbps, video business 384kbps-2Mbps, data business 64kbps- 2Mbps.

By obtaining the communication requirements of the equipment in the power system in the predetermined area, the number and type of terminals can be determined according to the communication requirements, so as to facilitate the deployment of subsequent base stations.

Optionally, determining the deployment scheme of base stations in the predetermined area according to the number and types of terminals includes: obtaining coverage information of each base station, where the coverage information includes one of the following: single-site coverage area, single-site coverage redundancy coefficient , regional regularity coefficient, self-owned site deviation coefficient; obtain the coverage planning result according to the coverage information of each base station; use the coverage planning result as the deployment plan of the base station in the predetermined area.

It should be noted that, in the above coverage information, the coverage area of a single station is the coverage area of each base station, and the coverage area of a single station corresponding to different application scenarios is also different. For example, the application scenario can use 230MHz single-site coverage, specifically including 30m hanging height and 22.4kbps edge rate. In order to meet service reliability, the number of base stations in a predetermined area conforms to the redundancy coefficient through the coverage redundancy coefficient of a single station. The above-mentioned single-station coverage redundancy coefficient is a parameter for adding base stations in a predetermined area to ensure the reliability of the base station. The higher the level of the preset area, the corresponding single-station coverage redundancy coefficient. For example, the single-site coverage redundancy coefficient in the central urban area is higher than that in the remote suburbs. The above regional regularity coefficient is a parameter used to adjust the number of base stations based on the actual coverage area of a single station based on each base station being affected by environmental factors such as terrain and topography. In general, the predetermined area may involve mountains, waters, etc. The actual area is not regular, and the coverage area of a single station will be small to a certain extent, which can be adjusted through the area regularity coefficient. The precondition for single-site coverage area estimation is based on a uniformly distributed site layout, which is a balanced network structure. Generally, the location of self-owned property points is difficult to meet the requirements of a balanced network structure, so it is necessary to introduce the self-owned site deviation coefficient . That is, the self-owned station deviation coefficient is a parameter used to adjust the uniform distribution of base stations, and the calculated number of base stations can be made more accurate by using this parameter.

Further, the coverage planning result can be obtained according to the coverage information of each base station, and the coverage planning result can be used as the deployment scheme of the base stations in the predetermined area. Based on the above coverage planning results, the minimum number of base stations meeting the coverage requirements in the predetermined area can be obtained.

Optionally, the coverage planning result includes the number of base stations, and the coverage planning result obtained according to the coverage information of each base station includes: number of base stations=power supply area/single station coverage area×redundancy coefficient, where redundancy coefficient=self-site deviation degree coefficient × regional regularity coefficient × single station coverage redundancy coefficient.

During implementation, the coverage planning results include but are not limited to the number of base stations, where the number of base stations can be calculated by the following formula: number of base stations = area of power supply area / coverage area of a single station × redundancy coefficient, where redundancy coefficient = self There are station deviation coefficient × area regularity coefficient × single station coverage redundancy coefficient. Since coverage information of each base station is involved in the formula, the calculated number of base stations is more accurate.

It should be noted that, in practical applications, each base station has the same performance parameters, and the performance parameters of each base station can be adjusted according to actual requirements, so as to adapt to different application scenarios.

Optionally, the method further includes: determining the deployment scheme of the backhaul network according to the deployment scheme of the base station, where the backhaul network is used for data backhaul by the base station.

The above-mentioned determination of the deployment plan of the backhaul network according to the deployment plan of the base stations includes: obtaining the location information of each base station, wherein the location information includes at least the geographic location and a network address; establishing a network backhaul channel according to the location information of each base station; The backhaul channel determines the deployment scheme of the backhaul network. Furthermore, the service information of the terminal corresponding to the location information of the base station is transmitted through the backhaul network through the backhaul network, which not only satisfies the requirement for information resource transmission, but also realizes data sharing among base stations.

It should be noted that after determining the deployment plan of the core network according to the deployment plan of the base station and the required capacity of the communication network, it also includes: establishing a data channel between the core network and the background service system; determining the deployment plan of the bearer network according to the data channel . Wherein, the deployment scheme of the bearer network includes a first router and a second router, the first router is used to carry production control services, and the second router is used to carry management information services. Through this method, a safe transmission channel can be provided for different business needs.

An optional implementation manner of the present invention is described below.

Fig. 2 is a schematic diagram of the architecture of the power system communication network deployment according to an optional embodiment of the present invention. As shown in Fig. 2, it can be applied to construct a 230MHz wireless private network, and the specific functions of each component are as follows:

Core network equipment: responsible for terminal authentication and authentication, data encryption, IP address management, mobility management, etc., and communicates with the main business station through the backbone communication network.

Base station equipment: As the core network element of the wireless network, it provides main functions such as wired and wireless protocol conversion, wireless resource management and allocation, terminal access and control, etc.

Wireless private network terminal module: The communication terminal is connected with the power service terminal, and cooperates with the base station system to transmit the uplink and downlink data of the power terminal. The physical and protocol specifications of the communication module conform to the State Grid Regulations, and can be directly embedded in the corresponding power terminals to reduce the complexity of implementation.

In addition, the wireless private network management system is used for configuration management, performance management, fault management, software management, etc. of the wireless network; and configures an interface server with an amplitude modulation (Agile Manufacturing, AM) system.

Based on the above architecture, a power system communication network deployment processing method is implemented, and the specific steps are as follows:

(1) Base station planning

The base station planning is based on the terminal planning, comprehensively considering the coverage planning and capacity planning, to finally determine the planning scheme of the electric wireless private network base station. At present, the wireless private network mainly has limited coverage and low capacity utilization, so there is no need to consider capacity limitation in the planning stage.

1. Coverage planning

Coverage planning is an important method in network planning. Coverage planning needs to consider various path loss, link balance and coverage influencing factors in the propagation process. Based on this, determine the maximum possible coverage area of each base station, and then estimate the coverage requirements in the area. The minimum number of base stations.

In the implementation process, the coverage planning method is used to plan the specific power supply area, as follows:

(1) Single station coverage area

According to the top-level design guidelines, the specific power supply area is planned and calculated according to the theoretical coverage area of a single station in the typical scenario of "30m hanging height, 22.4kbps edge rate". The reference values are shown in Table 1:

Table 1

It should be noted that all the above specific power supply areas are covered by 230MHz.

(2) Single station coverage redundancy coefficient

In order to meet the requirements of high service reliability, according to the "Technical Guidelines for Planning and Design of Electric Power Wireless Private Network", the number of base stations requires a certain redundancy factor.

The single station coverage redundancy coefficients of various power supply areas are shown in Table 2:

Table 2

(3) Regional regularity coefficient

The area of the power supply area generally deducts mountains, waters, etc. The actual area is irregular, and the estimation of the area of a single station will lead to a small scale. Combined with the actual situation of each city, different areas and different scenarios in different cities, different types of power supply The coverage radius of the area is adjusted by a factor. Among them, the regional regularity coefficient is shown in Table 3:

table 3

(4) Own site deviation coefficient

The precondition for single-site coverage area estimation is based on a uniformly distributed site layout, which is a balanced network structure. Generally, the location of self-owned property points is difficult to meet the requirements of a balanced network structure, and the deviation coefficient of self-owned sites needs to be introduced.

During the implementation process, specific areas have their own site deviation coefficient values as shown in Table 4:

Table 4

(5) Coverage planning results

According to the number of base stations = power supply area / single base station coverage area × redundancy coefficient (in which redundancy coefficient = own site deviation coefficient × area regularity coefficient × single station coverage redundancy coefficient), it can be calculated based on coverage planning, Table 5 shows the number of planned base stations in various power supply areas in specific areas.

table 5

2. Base station planning conclusion

This time, there is no need to consider capacity constraints, and coverage planning is the final planning result.

(2) Core network planning

1. Configuration principles

The deployment method should be determined according to the business and construction scale of the electric power wireless communication private network, and it should be deployed in prefecture-level companies; it can be deployed in provincial (city) companies according to the scale and flow of business access.

For the area carrying millisecond-level load control services, two sets of core networks should be set up to respectively carry the business of the production control area (including load control business) and the business of the management information area.

The capacity of the core network should be reasonably determined according to the number of base stations planned in the coverage area and business demand forecasts.

The key units of the core network should be redundantly configured, and local or remote disaster recovery should be considered in areas with large network scales.

2. Number of configurations

In this embodiment, the core network is configured according to the prefecture-level deployment mode, and each prefecture-level city is configured with two sets of core networks.

(3) Backhaul network planning

1. Network principles

The backhaul channel of the base station should give priority to the company's own transmission resources. If the conditions are not available, the channel can be leased. The leased channel should meet the requirements of security, reliability and network management.

The end-to-end 1+1 or 1:1 protection mode is adopted on the line side of the backhaul channel, and the network where it is located needs to provide carrier-class service guarantee, and the end-to-end switching time of the service is less than 50ms in case of a failure.

2. Backhaul network solution

At present, some base station sites choose power supply stations or business halls, which do not meet the above-mentioned backhaul network channel requirements. Small transmission equipment needs to be deployed on site at the base station site, and through the nearby substation Synchronous Digital Hierarchy (SDH) equipment group At the same time, some sites need to be reinforced with optical cables to meet the dual routing requirements of the transmission line. With the construction of other communication network projects, this part of the deficiency can be made up at the same time as the wireless private network construction. Affect the construction of wireless private network. Therefore, the backhaul network only considers configuring two 155M optical port boards for each SDH equipment at the substation side for service access. FIG. 3 is a schematic diagram of a wireless private network deployment of a power system communication network according to an optional embodiment of the present invention. As shown in FIG. Necessary, effectively guarantee the development of various businesses.

(4) Bearer Network Planning

The wireless private network bearer network is used to provide the data channel from the wireless core network equipment to the background business system. During the specific implementation process, 20 new routers need to be added in each city of the bearer network, among which 4 routers are used to carry production control services, and 16 routers are used to carry management information services.

1. Production control area business

The corresponding business system for the control business carried by the electric power wireless private network is located on the city side. Add 4 CE routers on the city side (2 each for active and standby) and run the Virtual Router Redundancy Protocol (VRRP for short) to connect the core network equipment with the corresponding city-side business system.

2. Manage information business in large area

The management information business carried by the power wireless private network is subdivided into two sub-services: marketing and transportation inspection. The corresponding business system is located on the provincial company side, and the power data network provides a secondary virtual private network (Virtual Private Network, referred to as VPN) channel .

A single core network device cannot currently provide independent egress for multiple sub-services, and a router must be used to expand the number of ports to connect with the three VPN ports of the data network. Considering business isolation and possible future business access requirements, a total of 16 routers (8 for active and standby) are deployed on the city side.

Among them, 4 active and standby PE routers are connected to the core network equipment in the management information area through Gigabit links, which are used for the expansion of the core network ports, and distinguish various sub-services according to the IP address segment of the service terminal. The remaining 12 routers are divided into six groups (three groups for active and standby routers), and form a zigzag connection with the active and standby data network PEs. The six groups of CE routers are isolated from each other and are mainly used to expand service access, respectively carrying the business in the marketing area, the business in the transportation inspection area, and other services. Each group of active and standby CE routers is connected using the VRRP protocol to ensure that the backup mechanisms of each level are independent and do not interfere with each other. At the same time, in order to meet the port requirements for the newly added CE router to access the data network PE, two interface boards are added to the data network PE.
