At present, the power distribution self-healing protection technology can be mainly divided into a centralized control type and a master station local coordination type according to different implementation methods. The centralized control type distribution network self-healing mode is mainly characterized in that operation information and fault signals of a distribution network and distribution equipment are collected in real time according to a distribution automation terminal or a self-healing protection device, and switching of switching equipment is automatically calculated by a distribution main station or remotely controlled in an artificial mode, so that optimization of the operation mode of the distribution network, quick fault isolation and power restoration are realized. And the main station cooperation type on spot does not need the control of the distribution main station or the distribution substation when the distribution network has a fault, and realizes fault location or isolation through modes such as mutual communication, protection cooperation or time sequence cooperation of the distribution automation terminals. The power distribution main station takes an automatic switch protection signal and a switch tripping signal as criteria, combines the topology of a primary grid frame and the load distribution condition, comprehensively analyzes an optimal power recovery scheme, and remotely restores the power supply of a non-fault area.

Especially in the field test process, the test can not be carried out in many areas due to the restriction of communication blind areas.

The master station can be electrically connected or in communication connection with the tester, the tester can be electrically connected with the terminal to be tested, and the terminal to be tested can control the on-off state of a switch in the power circuit. The master station can be used for processing data, such as generating a test script, generating a self-healing test result and the like; the tester can output an analog voltage signal and/or an analog current signal to the test script, so that the terminal to be tested can be tested. The Terminal to be tested may be, but is not limited to, various Distribution automation terminals and various self-healing protection devices, such as FTU (Feeder Terminal Unit, Distribution switch monitoring Terminal), DTU (Data Transfer Unit, Data transmission Unit), and TTU (Distribution Transformer Supervisory Terminal).
In one embodiment, as shown in fig. 2, a power self-healing test method is provided, which is described by taking the method as an example for the master station in fig. 1, and includes the following steps:
The power line topological graph can be used for indicating the topological structure of each power distribution automation terminal in the power system, and the terminal to be tested can be part or all of the power distribution automation terminals in the power line topological graph. The target fault terminal is a power distribution automatic terminal simulating a fault; the target fault type is a specific type of fault which appears in a simulation mode; the target switch signal is a prediction remote control action for realizing fault self-healing of the terminal to be tested when the target fault terminal has a fault of a target fault type.
Specifically, the master station may respectively determine the test script corresponding to each terminal to be tested and the target switch signal corresponding to each terminal to be tested according to the power line topology, the target fault terminal, and the type of the target fault terminal by using a correlation algorithm. The test script can comprise a normal test time sequence, a fault test time sequence and an isolation test time sequence, wherein the normal test time sequence can be a voltage signal and/or a current signal of the terminal to be tested before a target fault terminal fails, and the voltage and current change of the terminal to be tested before the fault occurs can be simulated through the normal test time sequence; the fault test time sequence can be a voltage signal and/or a current signal of the terminal to be tested when a target fault terminal fails, and the voltage and current change of the terminal to be tested when the fault occurs can be simulated through the fault test time sequence; the isolation test time sequence can be a voltage signal and/or a current signal of the terminal to be tested when the target fault terminal is subjected to fault isolation, and the voltage and current change of the terminal to be tested when the fault is isolated can be simulated through the isolation test time sequence.
According to the self-healing protection technical principle, when the fault terminal and the fault type are known, each node in the test line can be calculated according to the self-healing protection technical principle, namely the voltage and current change of each terminal to be tested before, during and during fault isolation, and the action protection logic of the terminal to be tested.
The actual switch signal is a switch control signal transmitted to the switch when the terminal to be tested identifies that the power system has a fault.
Specifically, the master station transmits each test script to the corresponding tester, and the test scripts can be issued asynchronously or synchronously to each tester. Furthermore, the master station can be in communication connection with the tester, so that the test script can be issued to the tester through a network; the master station can also be electrically connected with the tester, so that the test script can be issued to the tester through a serial port and the like; the master station can also issue the test script through an intermediate device, such as a Universal Serial Bus (USB) Memory, a secure digital Memory (SD) card, and the like, and the master station can transmit the test script to the intermediate device, and the intermediate device can be electrically connected to the tester, so that the test script on the intermediate device can be transmitted to the tester.
The master station tests and transmits each test script to the corresponding tester, and the test scripts instruct the tester to respectively output a normal test time sequence, a fault test time sequence and an isolation test time sequence to the electrically connected terminal to be tested, so that the occurrence of faults can be simulated. And the terminal to be tested receives the normal test time sequence, the fault test time sequence and the isolation test time sequence, and outputs an actual switch signal according to the received test time sequence so as to complete the remote control protection action. The tester can receive an actual switch signal transmitted by the terminal to be tested, and further, the tester can transmit a corresponding switch feedback signal to the terminal to be tested according to the received actual switch signal so as to simulate the operation state of the switch, thereby reducing the influence of the electric self-healing test on the electric power system.

The self-healing test result may be used to indicate a matching result between an actual switch signal of each terminal to be tested and a corresponding target switch signal, for example, the self-healing test result may include a terminal to be tested where the actual switch signal matches the target switch signal, or may include a terminal to be tested where the actual switch signal does not match the target switch signal, or may include a matching condition of each terminal to be tested.

Specifically, each test script can comprise starting time, and the starting time of each test script can be the same, so that multiple testers can work at the same time, and synchronous testing is realized. Specifically, the test script is used for indicating the tester to respectively output a normal test time sequence, a fault test time sequence and an isolation test time sequence to the terminal to be tested when the satellite synchronization time reaches the starting time. According to the method, the testers are synchronized by satellite time according to the appointed time for issuing the test script, work simultaneously, and output analog voltage signals and analog current signals to the corresponding terminal to be tested according to the test script.
