For clearer illustration, the application and advantages of the intelligent power distribution station management terminal of the virtualization technology are further illustrated by a power distribution station outage management application example.
Power supply enterprises are a special service industry engaged in the sale of electric power commodities. With the continuous prosperity of social economy, the improvement of the quality of life of people and the continuous improvement of the electric power dependence, the demand and the requirement of more and more electricity utilization customers on electric power service are continuously improved. How to promote the power supply service quality and improve, reduce the power failure maintenance time, realize that power supply time 98 promotes to two 9, even 3, 9, 4 9, the power supply service enterprise is puzzled always. At present, power failure repair service is realized, the management of repair personnel is comprehensively enhanced, the repair efficiency is improved, the work quality is improved, the bottleneck is reached, and the power failure repair time is difficult to shorten. And the degree of automation of current low pressure platform district is lower, and after the maintenance personal received the work order, need comb the circuit in platform district at first, when seeking the power failure reason, often this process will consume longer time. If the power failure maintenance time can be further reduced, the special change from passive emergency repair to active emergency repair is realized, and the self-healing capacity of the power supply event of the low-voltage transformer area is improved.
In order to realize the power failure management of the low-voltage transformer area, the intelligent distribution transformer area management terminal of the virtualization technology in the embodiment needs to be installed in the existing transformer area, the intelligent distribution transformer area management terminal of the virtualization technology installs the power failure management application of the transformer area in the functional application module through the virtualization module, and the power leakage protection switch of the transformer area is replaced by an intelligent power distribution transformer area management terminal with the function virtualization technology such as metering, controlling and communication. The external hardware interface of the intelligent power distribution station management terminal is connected with each power distribution device of the station area, the intelligent power distribution station management terminal is connected with each power distribution device through the power distribution device driving module, the station area topology generation is achieved through edge calculation, and the station area is fully collected.
In this example, the topology generated by the edge calculation is shown in fig. 3, and the platform area topology includes 1 distributor incoming line switch, 2-3 distributor outgoing line switches, and 4-10 low-voltage branch boxes.
The low voltage distribution blackout management principle is shown in fig. 4. The low-voltage power distribution power failure management is based on basic information such as a power grid model, real-time power grid operation data, equipment information and user information, received power failure information (distribution network fault information such as switch action information and distribution transformation alarm information, customer repair information, planned power failure information and marketing power failure information) is researched and judged, and if multiple pieces of power failure information are received at the same time, the processing sequence can be as follows: the system comprises switch action information, distribution transformer alarm information, customer repair information, planned power failure information and marketing power failure information. When a fault occurs, the fault information may be missed and mistakenly reported. By means of integrating different types of fault information generated by the same fault, calling and testing real-time operation data and the like, false reports are reduced. For the condition of failure report, the next-level fault information has a supplementary effect on the previous-level fault, so that the fault diagnosis is more comprehensive. The intelligent power distribution area management terminal is based on low-voltage power distribution area information full collection, after power failure alarm information sent by low-voltage switch action information or a user ammeter is received, the intelligent power distribution area management terminal can be matched with low-voltage topology according to the address of the user ammeter or the sent switch action information, the range of power failure influence is determined, and the power failure reason is determined to be application power leakage, overload or artificial cause according to collected fault information. After the edge calculation and analysis of the intelligent distribution station management terminal, a message of a power failure event is generated and sent to a distribution automation main station (the message contains the customers affected by the power failure, the level of a root node switch of the power failure is the level, and a reference geographical position and possible reasons causing the accident are given). The master station generates work order information according to the message, sends the maintenance work order to the hands of maintenance personnel, and then the maintenance personnel can quickly arrive at the fault point to analyze and maintain according to possible reasons. Based on the automation, before saving, after a power failure event occurs, a customer informs customer service personnel through a 95598 telephone, the customer service personnel records, then the customer generates a work order by the information input system, and sends the work order to a complex process of maintenance personnel, so that the power failure time is greatly shortened, and active repair reporting is realized.
The intelligent power distribution station management terminal performs topology generation every 12 hours and when power supply is returned after a power failure event occurs in the station. Generally, the topology of a cell is fixed, and only a few loads are increased by live-line operation, so the generation interval of the topology can be generally set to 12 hours, but the load may be increased when the cell is powered off, so the topology generation operation is performed once after the power off is recovered.
Based on the local topological graph stored in the intelligent distribution area management terminal, when a power failure event occurs, the on-off state of the power failure rear stage and the data of the user meter may fail to be read, or the data can be read, the voltage is read singly, and the current data is zero. Therefore, the power failure event of the transformer area cannot be judged only according to the switch information, and comprehensive analysis and calculation are carried out according to the fully-collected data of the transformer area. The flow of the determination is shown in fig. 5. The method comprises the steps of firstly, fully collecting data of a transformer area, then analyzing, judging an abnormal type if the data is abnormal, determining an abnormal switch position if a switch sends a remote signaling abnormality, then reading a switch rear-stage switch and a user table state, then judging a line communication state, determining an interrupted user table address if the communication is interrupted, searching a root node in a topological graph according to the address, judging a line short line, analyzing a phase line, judging the position of the front-stage switch and the rear-stage switch, performing abnormal recovery, determining the root node switch which sends the abnormality if the communication data is normal and partial voltage current is zero, analyzing the voltage state of the front-stage switch and the rear-stage switch, determining the damage condition of the switch and the condition of the phase line, determining an abnormal position, and performing the abnormal recovery. If the partial voltage current in the data is 0, determining a root node switch sending an abnormality, if the switch sends a remote signaling abnormality, determining the position of the abnormal switch, then reading the state of a switch rear-stage switch and a user table, then judging the line communication state, if the communication is interrupted, determining the address of the interrupted user table, searching a root node in a topological graph according to the address, judging a line short line, analyzing the phase line, judging the position of the front-stage switch and the rear-stage switch, and performing abnormal recovery, if the communication data is normal, judging that the partial voltage current is zero, determining the root node switch sending the abnormality, analyzing the voltage state of the front-stage switch and the rear-stage switch, determining the damage condition of the switch and the condition of the phase line, determining the abnormal position, and performing the abnormal recovery.
In one example, in order to determine the power outage occurrence position, data to be analyzed by the intelligent distribution substation management terminal is shown in table 1.

| 6 | | 230V | 3 | Combination of Chinese herbs | Is | 1xxxxx1 | |||
| 7 | | 230V | 1 | Combination of Chinese herbs | Is normal | 1xxxxx2 |
The power failure management application of the intelligent power distribution station management terminal can perform edge calculation on the table 1 data every 100mS according to process scheduling, when the voltage, current, remote signaling and communication are found to be abnormal, the edge calculation is performed rapidly according to the flow shown in the figure 5, the fault position and possible fault reason analysis are completed through calculation, and a message is generated according to the result and sent to the power distribution automation main station.
The situation that the emergency repair efficiency of a power supply service enterprise is low and the automation service level is backward is solved through the power failure management application, and the power supply reliability time is also prolonged. At present, data collected by an intelligent power distribution station management terminal is limited, a database is not generated for a plurality of fault types, along with the wide application of the intelligent power distribution station management terminal, data generated when various power failure faults occur are collected on a large scale, independent artificial intelligence learning is carried out on various events, a judgment basis is generated, data model comparison is carried out through edge calculation, reporting of a master station of the power failure events can be realized in the future, the types of the faults can be generated, and the types of the faults can be reported to the master station in the same time in a maintenance mode, at the moment, maintenance personnel can complete power failure repair in a shorter time, the power failure time is further shortened, and users can achieve high recognition on power supply enterprise services.
