dq0 Transformation Used in the Series Active Power Filter

串联型有源电力滤波器是为解决用户端供电电压中存在的电能质量问题而设计的一种有源滤波器,谐波检测方法在有源滤波技术的研究中占有重要地位。本文基于dq0坐标系下三相电路广义瞬时无功功率的理论,提出了一种谐波电压检测方法,并把该方法成功地应用于串联型有源电力滤波器的补偿电路中。理论分析和仿真结果均表明,这种谐波电压检测方法是正确有效的。

The main goal of the series active power filter（SAPF） is to solve the various voltage distortions at custom terminal.The approach of harmonic voltage detection has an important role in the reseach of APF. This paper presents an approach of detecting harmonic voltage based on the generalized instantaneous reactive power in dq0 coordinates. It is demonstrated by theoretical analysis and simulation results that the proposed method of harmonic voltage is correct and valid.
