Embodiment Construction

[0044] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0045] At present, in the testing process of the distribution network self-healing protection technology, it is necessary to rely entirely on the traditional relay protection tester and manually build a test environment for testing. Especially in the process of on-site testing, due to the constraints of communication blind spots, it is impossible to carry out testing in many areas.

[0046] The power self-healing test method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the main station can be electrically ...

Abstract

The invention relates to an electric power self-healing test method, device and system, a main station and a tester. The method comprises the following steps: respectively generating a test script anda target switch signal corresponding to each to-be-tested terminal according to a power line topological graph, a target fault terminal and a target fault type; wherein the test script comprises a normal test time sequence, a fault test time sequence and an isolation test time sequence; transmitting the test script to a corresponding tester; wherein 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 to-be-tested terminal, and acquiring an actual switching signal of the to-be-tested terminal; and receiving the actual switching signals transmitted by each tester, matching the actual switching signals with the target switching signals, and obtaining a self-healing test result according to a matching result. According to the invention, the test scripts and the target switch signals can be automatically generated and issued without manual calculation, and subjective errors are avoided, so that the test efficiency of the self-healing test and the accuracy of the self-healing test result are improved.

Description

technical field [0001] The present application relates to the technical field of power systems, in particular to a power self-healing test method, device, system, master station and tester. Background technique [0002] With the development of power technology, power distribution self-healing protection technology has emerged. Distribution self-healing protection technology uses automated terminals or automation systems to monitor the operating status of distribution lines, so that line faults can be detected in time, and faulty areas can be diagnosed and isolated, and power supply in non-faulty areas can be automatically restored. [0003] At present, according to different implementation methods, power distribution self-healing protection technology can be mainly divided into two types: centralized control type and master station local coordination type. Centralized control distribution network self-healing mode is mainly based on the distribution automation terminal or s...
