Abstract
The small current grounding System fault if not removed in time, there may be a further expand the short-circuit fault for alternate with, to power System caused heavy loss based on the Matlab software Simulink and SimPower System toolbox for platform, in the small current grounding System non-ground neutral way one-phase ground fault model, and by using the amplitude of zero sequence current phase discrimination fault line and the fault phases, which testified the zero sequence current ratio than the method of photograph of non-ground neutral way one-phase ground fault the effectiveness of discrimination.关键词
