摘要
Abstract
A fault location method based on hybrid intelligent algorithm for high voltage direct current (HVDC) transmission line is proposed. It corrects the results of fault location method based on genetic algorithm by the way of neural network algorithm, with the ranging accuracy improved when there are faults at two terminals of transmission line. Inheriting the advantages of fault location method based on genetic algorithm, the proposed method can locate faults with two terminals’ voltage and current of line in the time domain and is free from the effect of fault position and transition resistance. What’s more, the influence on ranging accuracy by line parameters deviation is greatly reduced. The proposed method is simulated by PSCAD and MATLAB, the simulation results show that the proposed method is valid and the combination of neural network algorithm and genetic algorithm can locate the fault on HVDC transmission line accurately and quickly.关键词
