Test method of power distribution network self-healing system, electronic equipment and storage medium

Abstract

The invention discloses a test method of a power distribution network self-healing system, electronic equipment and a storage medium. The test method comprises the steps: dividing each node of a power distribution network into a plurality of minimum self-healing units according to a topological graph of the power distribution network and a preset division rule; determining a test scheme according to a fault self-healing process of network directed traversal, wherein the test scheme comprises a self-healing scheme corresponding to each minimum self-healing unit; constructing a power distribution network self-healing system model according to the test scheme, and determining an objective function and constraint conditions of the power distribution network self-healing system model; calculating the power distribution network self-healing system model according to a genetic algorithm and a particle swarm algorithm, and finally obtaining a test result of the power distribution network self-healing system, wherein the test result comprises branch closing, branch opening, switching action times and test time. The number of feeder lines needing to be traversed in the test process of the self-healing system can be effectively reduced, the measurement scale of terminal equipment in the self-healing process after a fault occurs is reduced, and the test speed is improved by reducing the test complexity.

Description

technical field [0001] The present application relates to the technical field of smart grid, in particular to a test method, electronic equipment and storage medium of a distribution network self-healing system. Background technique [0002] The structure of modern distribution network is changeable and the operation mode is complex, so the requirements for distribution automation are getting higher and higher. After a fault occurs in the distribution network, the self-healing system must focus on shortening the power outage time, improving the fault handling ability, minimizing the power outage loss, and improving social and economic benefits. The correctness and rapidity of the self-healing process are important indicators of the active distribution network. In the process of quickly restoring power supply, the relay protection function of the distribution network terminal quickly isolates the fault, and at the same time locates the fault location, starts the self-healing...
