基于单周控制和i_p-i_q检测法的有源电力滤波器研究

Research of active power filter based on one-cycle control and i_p-i_q detection method

针对基于单周控制的有源电力滤波器只能同时补偿谐波和无功分量的问题,提出了一种基于单周控制和ip-iq检测法的有源电力滤波器的设计方案。ip-iq检测法检测出的含有谐波或无功分量或两者皆有的基波分量作为单周控制器的参考信号,电源电流信号作为单周控制器的输入信号,这2个信号通过单周控制器生成补偿电流,从而实现单独补偿谐波或同时补偿谐波和无功分量的目的。仿真与实验结果验证了该方案的可行性。

In view of problem that active power filter based on one-cycle control can only compensate harmonic and reactive component simultaneously,a design scheme of active power filter based on one-cycle control and ip-iq detection method was proposed.Fundamental components including harmonic or reactive component or the both detected by ip-iq detection method are took as reference signal of one-cycle controller,signal of power current is took as input signal of one-cycle controller.The two signals generate compensation current through one-cycle controller,so as to realize the purpose of compensating harmonic individually or compensating harmonic and reactive component simultaneously.The simulation and experiment results validate feasibility of the scheme.
