Simulation of transmission line to detect single line to ground fault location based on improved impedance method
In the power system, the frequency of transmission line failure is high, in a short time to determine the location of the failure of the power company is particularly important. Accurate fault location ensures the stability of the power system operation and also helps to analyze the specific grid. In this paper, an effective single line to ground fault location algorithm is used to determine the position of the fault point using fault current, fault voltage and line parameters. And the simulation is carried out by Matlab, that results are affected by the line reactance.
