Abstract: Due to the high cable ratio of city grid，the harmonic pollution is aggravated. For the buses with high harmonic voltage content，it is necessary to evaluate the harmonic emission level of the utility side and customer side. Most of the existing evaluation methods are based on two assumptions：1）the harmonic ...
