The invention discloses a distribution network ground fault test system and method, comprising: a control terminal acquires a test request indicating a selected ground fault test in a ground fault test under a distribution network network with multiple structures, based on the The test request generates the first configuration data and sends it to the distribution network structure switching device, generates the second configuration data based on the test request and sends it to the ground fault test device; the distribution network structure switching device according to the first The configuration data switches the distribution network network to the distribution network network that meets the test request; the ground fault test device switches the ground fault to the ground fault that meets the test request according to the second configuration data, so as to realize the selection. Simulation of ground fault tests. The ground fault test based on the method and system of the present invention has good economy and applicability, and meets the assessment and detection requirements of various distribution network equipment in different distribution network environments.
Description
technical field [0001] The present invention relates to the field of distribution network test technology, and more specifically, to a distribution network ground fault test system and method. Background technique [0002] Single-phase ground fault is a line fault that often occurs during the operation of the distribution network. When a fault occurs, it is usually necessary to quickly find the fault point through line selection, section selection, and phase selection equipment. In order to effectively verify the correctness of these intelligent equipment fault handling , it is necessary to simulate the real fault situation in the line, but because the 10kV side voltage is high, and there are different grid structures and load levels in the real power grid, it is also necessary to simulate sand, cement, soil, grassland, ponds, etc. In such a grounding scenario, there are problems such as heavy workload of simulating faults, difficulties in implementation, and potential safet...
