Study of the distribution and suppression of power system harmonic
Abstract：The nonlinear load causes massive harmonics of power system,which leads to power system voltage and current waveform distortion,poor quality of power and serious harm to the power system security and economical operation.Through survey and analysis,the distribution situation of coal mine electrical harmonic is obtained.According to this,the harmonic equivalent circuit model of coal mine equipment is listed.The solutions of uses active power filter to suppress high-order harmonics are given.
