摘要
介绍了三相四线并联型有源电力滤波器的基本原理,谐波检测方法以及控制策略。本文采用电流闭环PI结合电压前馈控制补偿电流发生环节,建立了并联型三相四线制有源电力滤波系统的仿真模型并进行了仿真。仿真结果表明该并联型有源电力滤波器能有效地补偿三相电流及中线电流,论证了其补偿电流检测方法及控制方案的可行性。
The basic principle, the harmonic detection method and the control strategy of three-phase four-wire shunt active power filter are introduced. A simulation model of three- phase four-wire shunt active power filtering system based on current close-loop PI adjustment and voltage feed forward control strategy is built and simulated in MATIAB/ SIMULINK. Simulation results show that the active power filter can realize three-phase currents and the neutral line current compensation effectually. The feasibility of the compensation current detection method and the control strategy are verified.
