摘要
分析了并联型和串联型电能质量补偿器分别补偿负荷电流和电源电压的缺陷及原因 ,介绍了串并联复合有源电力滤波器 ( SPAPF)同时补偿电网畸变电压和抑制负载谐波电流的运行机理 ,提出了适合于 SPAPF的电源畸变电压参考量比较检测法、负荷谐波电流 dq0检测法以及一种改进的稳定直流电容电压的 PI控制策略。
The shortcomings and causes of shunt active power filter and series active power filter in compensating load current and source voltage are analyzed. The operation principle of series parallel active power filter (SPAPF) is introduced, which can compensate the source distortion voltage and restrain the load harmonic current at the same time. The methods for detecting the source voltage distortion, the load current harmonic based on dq0 transform, and an improved PI control strategy for keeping the voltage at the DC link capacitor, which are fit for SPAPF, are proposed. The simulation results verify the correctness of the analysis and the validity of SPAPF.
