摘　　要：提出了一种瞬时无功电流全补偿控制策略,对瞬时无功全补偿装置进行建模,得出二阶的线性模型,并对三相瞬时有功电流进行定义,使网侧电流基频分量跟踪各相的瞬时有功电流,补偿后的电网侧电流与电源电压波形在相位上完全一致,实现瞬时无功全补偿。文中详细阐述了控制方法的原理。仿真结果表明了该方法的有效性及令人满意的性能。A control scheme which can realize the instantaneous reactive current full compensation is presented in this paper. We build a math model and obtain a second-order liner model due to the equipment of instantaneous reactive power full compensation .Then we de- fine the three-phase instantaneous active current, and make the current of the power source track the instantaneous active current of each phase .After compensation, the current waves have the same phase as the voltages in the side of power source, and the instantaneous reactive power full compensation is realized. The principle is expounded, and the simulation shows its effectiveness and satisfying performances.
