摘　　要：针对电力电子装置给电力系统带来谐波污染和功率因数下降的问题,建立了三相电流型PWM整流器在abc坐标系下的数学模型,并在该坐标系下通过控制三相电流型PWM整流器交流侧电流的基波和相位,进而间接控制网侧电流的间接电流。通过仿真和实验验证,该控制策略完全可以实现网侧电压电流单位功率因数,且直流侧电流趋于稳定。The electronic installation brings harmonic pollution to power system and descend power factor. In order to sovle the problem,mathematical model of 3-phase current-source PWM rectifiers are founded in abc stationary coordinate. The indirect current control strategy is adopted through controlling fundamental and phase of AC-side in 3-phase current-source PWM rectifiers. Computer simulation and experimental results show that unity power factor in network and stable current source in DC-link are obtained based on the control strategy.
