A Circuit Impedance Measurement Method Based on District Area and Fault Pre-judgment

At present, the research work on the distribution network area mainly focuses on the research of its load prediction and line loss, and the research on the related aspects of the topology of the district area is still lacking. This paper mainly uses the simulation modeling software to estimate the impedance parameters of each branch under the known situation of the network structure of the district area. This paper adds small interference based on Gaussian distribution in the process of post-processing data to reach the actual measurement situation. Then the method is applied to fault location and elimination of distribution network, which has certain significance for the fault elimination of distribution network.
