摘要：
Accurate fault location is significant to the city metro catenary fault investigation process. A theoretical analysis of the fault location method based on impedance calculation has been performed, using the voltage and current quantities from both end of the line, and the error sources were thoroughly studied. However, in practice the double-terminal electrical quantities used in the calculation may not be synchronous to one another, due to the different protection operating times at either ends of the fault. Another new location algorithm was proposed, which uses genetic algorithm to solve the problem. The simulation results show that the proposed new method has improved location accuracy.
