Description

Emergency Repair Information Release System for Electricity Users

technical field

The invention belongs to the technical field of electric power dispatching, and in particular relates to a system module for a power supply service command platform.

Background technique

The distribution network, that is, the distribution network, refers to the power grid that receives electric energy from the step-down distribution substation and distributes it locally through the distribution facilities or distributes it to various users step by step according to the voltage. It is composed of auxiliary equipment on the side, and the power distribution equipment mainly includes switchgear, distribution lines and distribution transformers.

The management of the distribution network within the power enterprise generally deploys different information management systems according to different demand angles. These information management systems mainly include but are not limited to:

Smart grid dispatching control system is an automation system for smart grid dispatching and production business, providing technical support for power grid operation monitoring, operation control, safety analysis, planning, decision-making assistance, dispatching management and other businesses;

Distribution Automation System, or DAS, is an automation system that enables power companies to monitor, coordinate and operate power distribution equipment in real time at a remote location. Electrical geographic information system (GIS) and demand side management (DSM) parts;

Power equipment management system, namely PMS, is a set of basic business software platform for the power industry developed based on model-driven and component-based ideas. Its database includes the entire grid equipment account, and the equipment number in the equipment account can be retrieved through the interface. and device name;

The electricity consumption information collection system of electric power users is a system for collecting, processing and real-time monitoring of electricity consumption information of electric power users. Functions such as information release, distributed energy monitoring, and information interaction of intelligent electrical equipment.

The power supply service command platform is a power user service system deployed for the power supply service command center, which realizes the integrated operation of command, coordination, monitoring, analysis and other services in the process of power supply service work. The platform has at least the following two technical requirements: a. Centralize the data of various internal information management systems to achieve unified scheduling; b. Provide credible information disclosure to external power users to achieve unified release. At present, the response process of power distribution network fault maintenance in the power supply service command platform is as follows: 1. After the call center receives the user's repair report, the call center enters the fault report work order into the first information management system. The repair work order is in the unprocessed state; 2. The power supply service command center retrieves the unprocessed fault repair work order in the first information management system, and distributes the unprocessed repair team to the first emergency repair team responsible for the maintenance area where the unconfirmed fault address in the work order is located. 3. The first emergency repair team will trace back the power supply link of the distribution network to find the fault point according to the unconfirmed fault address. If the fault point is under the jurisdiction of the emergency repair team, the repair time will be evaluated and reported to the power supply service command center. If the fault point is not under the jurisdiction of the emergency repair team, report it to the power supply service command center, and the power supply service command center will assign the second emergency repair team to continue to confirm the fault point, and repeat this step until a emergency repair team confirms that the fault point belongs to the emergency repair team. The emergency repair team will report the evaluation and maintenance time to the power supply service command center; 4. After the power supply service command center receives the evaluation and maintenance time, it will change the fault repair work order to the maintenance state, and evaluate the power outage range and register it to the mobile phone within the power outage range. Electricity users send outage notifications.

There are at least the following problems in the current distribution network fault information processing process of the power supply service command platform: 1. The power user number included in the fault repair work order can only confirm the power supply station area to which the user belongs, but the power supply station area is not the same as the maintenance area. Therefore, It cannot be directly used for the backtracking of the power supply link, and it still needs to manually go to the backtracking investigation; 2. If the fault repair work order does not contain the power user number, it only contains vague unconfirmed fault address information, which is difficult to be used for manual sorting to determine the maintenance area. 3. The information acquisition of the power supply service command center itself lags behind, and the internal information management system cannot be directly opened to external power users. The emergency repair process is opaque, which is easy to cause adverse effects, and does not meet the technical requirements of the communication of the power supply service command platform; 4. Distribution substation operation status, distribution transformer and user meter status, distribution line switch status and fault repair work order status. They belong to different information management systems and each has a certain incompleteness. It cannot directly provide reliable scheduling advice to the power supply service command center, requiring manual processing and a large workload; 5. The distribution network automation equipment cannot be fully covered, and the transmission of the call and measurement system The equipment is incomplete. For example, the existing distribution network branch switches are not fully automated, and information-based real-time query cannot be realized.

Chinese patent CN104965150B discloses a distribution network fault location method based on incomplete operation and distribution information fusion. The method locates the fault by backtracking the power supply link and analyzing the weight of the alarm equipment in the power supply link. The premise of this method is to assume that the alarm equipment can be directly located on the specific line of the power supply station area, but the actual situation is that most of the power distribution network fault repair work orders only carry the approximate address information, which is almost irrelevant to the address itself of the faulty power distribution equipment. Generally, the line and specific number of the faulty power distribution equipment cannot be determined through the fault work order, so the system is difficult to be practically applied to the power supply service command platform.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of this application.

In the embodiment of this application, as shown in FIG. 1 , the power supply service command platform includes a plurality of interfaces for communicating with any information management system within the power enterprise, and the interfaces include support software for communication protocols such as 61850 and TCPIP, gateways, routers and other hardware communication equipment, the information management system includes software, a general-purpose computer running the software, and sensors and controllers that collect primary or secondary side distribution network information, or other forms of IoT terminals. In the embodiment of the present application, the power supply service command platform can at least obtain fault repair information from the first information management system through the interface, obtain equipment account information from the second information management system, and obtain the outgoing switch of the distribution substation from the third information management system. The operation information is obtained from the fourth information management system for distribution network branch switch operation information, from the fifth information management system for distribution transformer operation information and user meter operation information, and from the sixth information management system for power equipment geographic information.

According to the technical solution provided by the present invention, the power distribution fault information processing system, emergency repair information release system and distribution network fault information notification system of the power supply service command platform in FIG. 1 can realize the technical function of the power supply service command platform through the following information transmission relationships: The network fault information processing system simultaneously receives the information of all the information management systems about the power equipment of each node in the tree structure. The information includes the callable and testable information and fault repair information of the power equipment. The fault repair information determines the fault; after the distribution network fault information processing system judges the fault successfully, the power supply service command platform sends the relevant emergency repair information to the outside through the emergency repair information release system and the distribution network fault information notification system to ensure the transparent operation of the power supply service. The information release system is mainly used for power users and related personnel to actively query the dynamic information of emergency repairs from the power supply service command platform. The distribution network fault information notification system is mainly used for the power supply service command platform to timely notify power users and related personnel who will be affected by power outages or emergency repairs. The following embodiments can be applied simultaneously on the power supply service command platform, or can be applied in combination with each other, or can be applied independently, but the simultaneous use can provide the best effect.

First of all, it should be noted that any power equipment in the distribution network does not necessarily have the same unique identification code in different information management systems, and may have different classification attributes according to business categories. Also, the same power equipment is managed by different personnel depending on the business. For example, a distribution transformer has equipment managers, emergency repair teams, and station managers who are responsible for daily maintenance, temporary emergency repairs and power The user service field is managed, and the management of each field is handed over at different times. The system cannot simply determine the manager through time, location, and service type.

Example 1

The embodiment of the present application first provides a method for processing distribution network fault information. As shown in FIG. 2 , the method may include the following steps:

S101: Divide distribution transformers into multiple distribution transformer groups according to their installation locations and subordinate upstream branch switches, mark the installation location of each distribution transformer on a digital map and select a regional map, each regional map covering at least one complete distribution group.

In the specific implementation, the unique identifier of the distribution transformer is extracted from the operation information of the distribution transformer, and the unique identifier is used to obtain the installation location of the distribution transformer registered in the geographic information of the power equipment through the equipment ledger information, and mark each location on the digital map. The installation site of a distribution transformer; the distribution transformers that are geographically close and belong to the same upstream branch switch are divided into the same distribution transformer group, and a closed curve including all distribution transformer installation locations of a distribution transformer group is drawn on the digital map , the area enclosed by the closed curve is the power supply area of the distribution transformer group, and the power supply area is in one-to-one correspondence with the distribution transformer group; a partial map that at least completely contains a power supply area in the digital map is selected as the regional map. In a regional map, The power supply area that is completely covered by the area map is called the core power supply area, and the power supply area that is not completely covered by the area map is called the surrounding power supply area.

As shown in Figure 3, in this embodiment, the entity relationship diagram between distribution transformers, distribution transformer groups and regional maps, distribution transformers and distribution transformer groups in the distribution network are in a many-to-one relationship, and distribution transformer groups and regions The map is a one-to-many relationship, so the same distribution transformer may appear in multiple regional maps, especially for distribution transformers located near two adjacent power supply areas, it is more likely to appear on multiple regional maps . According to the above method, any address in the digital map appears on at least one regional map, and may also appear on multiple regional maps.

Those skilled in the art know that there may be multiple branch switches between any distribution transformer and the distribution substation. Therefore, when the distribution group is divided according to the branch switches, if the branch switch closer to the distribution substation is selected, the The more distribution transformers may be included in the distribution transformer group, and the selection of different branch switches will affect the granularity of the distribution transformer group. The local granularity can be chosen according to the specific distribution density of distribution transformers, but it should be noted that, no matter how grouped, any distribution transformer must have its own distribution transformer group and corresponding power supply area.

S102: Read the fault repair report information, make a corresponding relationship between the fault repair report information and the regional map according to the fault address information thereof, and generate a regional fault information table corresponding to each regional map.

During the specific implementation, marking is made on the digital map according to the street and community addresses of the fault address information. According to the constraints on each regional map in step S101, the address appears on at least one regional map. When all fault addresses are marked After the information, each regional map will contain the fault address information within its coverage, and organize all the fault address information covered by a regional map into a regional fault information table, which includes the information shown in Figure 4. The entity relationship of the fault warranty information and the necessary additional information fields mentioned above, those skilled in the art can add additional information fields to the table according to the specific description of this application, or compress the table by linking sub-tables. Both should describe the entity relationship shown in Figure 4.

For a piece of fault repair information, it can be a record with the following structure in the information management system.

message ID source System ticket number Repair address Repair content Electricity user number 358 95598 201809XXXXXX XX Street XX Community The wires are on fire, and many households have no electricity 103XXXXX509

As shown in FIG. 4 , in the entity relationship diagram between the fault report information and the area map in this embodiment, the address mark of any fault report information may appear in multiple area maps, and any area map may also contain multiple fault alarm information.

S103: Read the regional fault information table, mark the fault repair information carrying the power user number as the A-type fault repair information, and mark the fault repair information without the power user number as the B-type fault repair information; the fault repair information carries the fault Address information.

S104 , perform a graded retrospective recall test on the repair report information of the A-type fault, and determine the fault type.

In the specific implementation, firstly, the power equipment in the primary side of the distribution network needs to take the distribution substation as the root node, and establish a tree structure along the flow direction. Each node in the tree structure corresponds to a power equipment, and the power equipment includes the distribution substation outlet. Switches, distribution branch switches, distribution transformers, and power user meters, as shown in Figure 5, form a four-layer tree structure of stations, lines, transformers, and households. Among them, there can be multiple outgoing switches 1 and 2 in the distribution substation. The distribution branch switches 11, 12, 21, 22, 111, 112 may have multiple layers, and the distribution transformers 111, 112 to the user may also have three-phase intermediate layers. The corresponding relationship between the nodes of the tree structure and the power equipment is: the outlet switch of the distribution substation corresponds to the station layer, the distribution branch switch corresponds to the line layer, the distribution transformer corresponds to the strain layer, and the power user meter corresponds to the household layer.

In specific implementation, when the power equipment indicated by the distribution network fault information cannot perform the call test, the call test result of the power equipment is estimated by the call test result of its upstream equipment or/and the downstream equipment. The corresponding distribution transformer operation information is inquired through the power user number of the Class A fault repair information, and the relevant distribution transformer is called for testing. If the distribution transformer has power, the fault repair information is judged to be a low-voltage fault. If there is no electricity, it is temporarily marked as a high-voltage fault. If the distribution transformer does not respond, it will be transferred to the joint research and judgment unit for analysis. The electricity user electricity information collection system provides the call and test data of electric energy meters such as the line general meter, the station area general meter, and the power user meter. Combined with the call and test data of the line general meter, the station area general meter, and the power user meter, it can assist in judging nodes. Whether there is a fault, such as whether the line meter at the outlet of the outlet switch 1 of the distribution substation has current, it can be judged whether the outlet switch 1 of the distribution substation is closed to supply power, and the line meter or the station area meter at the outlet of the distribution branch switch 11 can be It is determined whether the distribution branch switch 11 is charged.

The above is equivalent to explaining an application method of estimating the call test result of the power equipment through the call test result of the upstream equipment or/and the downstream equipment. Regarding the estimation algorithm, either the algorithm disclosed in the patent provided in the background art can be used, or the The following methods: 1. Set the current equipment to a fault-free state; 2. If the upstream equipment is normal, the current power equipment or downstream equipment is considered to be faulty; otherwise, the current equipment is considered to be fault-free; 3. If the downstream equipment has normal test data, the side Judging that the current power equipment is normal; 3. Iteratively traverse all upstream equipment and downstream equipment related to the current power equipment; 4. If there is a confirmed fault judgment, set the current equipment to a faulty state and end the iterative traversal, and output the current equipment after iterative traversal. fault state. Obviously, those skilled in the art can optimize the unsubscribe algorithm according to the description of the present application to further improve the operation efficiency. S105, call and test the distribution transformer in the map of the area where the repair report information for the Class B fault is located, and determine the fault type.

During specific implementation, through the judgment method of the tree structure as described in S104, call and test the distribution transformer in the area map where the fault repair report information is located, and then judge the fault type.

S106 , if the fault type is a low-voltage fault, assign a low-voltage emergency repair team to a point in the area map where the density of fault repair information is extremely high to implement emergency repair; if the fault type is a high-voltage fault, send the high-voltage fault information to the high-voltage emergency repair team.

The emergency repair task information involved in the A-type fault repair information and the B-type fault repair information are respectively judged by the digital map and the test data. The emergency repair task information includes the information distribution network fault type and fault point location.

The call, test, and judgment unit 601 is used to establish a tree structure along the power flow direction for the power equipment in the primary side of the distribution network with the distribution substation as the root node. Each node in the tree structure corresponds to a power equipment. When the distribution network fault information When the indicated power equipment cannot perform the call test, the call test result of the power equipment shall be inferred from the call test result of its upstream equipment or/and downstream equipment;

The fault report and repair information processing unit 602 is used to divide the distribution transformer into a plurality of distribution transformer groups according to its installation location and the subordinate upstream branch switch, mark the installation location of each distribution transformer on the digital map and select a regional map, Each regional map covers at least one complete distribution and transformer group; read the fault repair information, make the corresponding relationship between the fault repair information and the regional map according to the fault address information, and generate the regional fault information table corresponding to each regional map;
