本文借助于对称分量法分析和证明了瞬时无功理论方法在三相四线并联有源电力滤波器(SAPF)中的适用性,然后就电网电压发生畸变对SAPF的影响进行了讨论,最后从仿真和实验两方面证明了以上分析的正确性。
This paper analyzes and proves the applicability of instantaneous reactive power theory method in three-phase four-wire shunt active power filter (SAPF) by means of symmetrical component method, and then discusses the influence of grid voltage distortion on SAPF. Finally, The simulation and experiment prove the correctness of the above analysis.
