Voltage Sag Source Location based on Comprehensive Criterion and Neural Network Method

Abstract

In order to solve the disputes caused by voltage sag, this paper proposes a comprehensive criterion of voltage sag location based on the traditional voltage sag location method. This criterion combines the characteristic information of voltage sag, and trains the neural network with the comprehensive criterion to locate the voltage sag source. Compared with the traditional methods, the simulation results show that the proposed method has higher accuracy and immunity to voltage sags under various faults, especially under asymmetric faults.
