Distribution Network Fault Location Based on Rough Set and Data Fusion

摘要

Under the background of the popularization of smart meters and the further upgrading of centralized reading equipment, relying on two-way communication system in some non-measurement and control areas of distribution network, power enterprises can also obtain users'multiple electricity values through smart meters in time or in real time. Therefore, for a given distribution network topology, in the non-measurement and control area of the distribution network where the user's meter information has been collected, the user's smart meter information, the user's telephone complaint information and the equipment alarm information are taken as the condition attributes of the fault classification to establish the fault decision table, and find the minimum reduction. Then, according to the three kinds of information, attribute matching of the reduced fault decision table is carried out to determine the fault section. The simulation results show that the proposed method greatly reduces the number of complaint calls needed for fault location and shortens the time of fault location.
