将有源电力滤波器与无源电力滤波器相结合，构成混合型电力有源滤波器（ＨＡＰＦ），可以降低谐波补偿系统的成本，改善滤波性能，提高实用价值．本文对利用ｄｑ变换计算谐波电流的方法作了分析，在Ｆ．Ｚ．Ｐｅｎｇ的串联ＨＡＰＦ的结构基础上，对其控制方案作了研究和改进，将两种有源滤波器的原理结合在一起，使其同时能对电网谐波电压和负载谐波电流进行有效抑制，并对高次谐波和低次谐波都具有很好的抑制效果．通过仿真分析证明了其可行性．
Combining the active power filter and the passive power filter to form a hybrid active power filter (HAPF) can reduce the cost of the harmonic compensation system, improve the filtering performance and increase the practical value. In this paper, the use of dq transform harmonic current calculation method was analyzed in F. Z. Peng based on the structure of the series HAPF, the control scheme was studied and improved, the principle of the two active filters together to make it at the same time on the grid harmonic voltage and load harmonic current effectively suppressed, And has a good inhibitory effect on higher harmonics and lower harmonics. Through the simulation analysis proved its feasibility.
