Abstract

Base on the research results of traditional harmonic direction leakage protection and combined with its shortcomings, proposes "Start at zero sequence voltage and its mutation, Alignment at the result of compared with amplitude and phase about 5th harmonic of zero sequence current" and take 80C196 as the core microcomputer application system. By selecting 6 kV high-voltage grid as a mine simulation object, simulating a leakage circuit of high-voltage power grid in arbitrary, the simulation results show the improvement of scheme\´s sensitivity and reliability.
