摘　　要：提出一种适用于高压大容量环境且投资成本较小的新型混合有源滤波器(HAPF)。在谐波检测方面,利用系统样机验证了基于坐标变换的离散傅里叶变换(DFT)滑窗迭代谐波电流检测算法;在谐波电流补偿输出的控制算法方面,总结出一种基于递推积分PI和离散滑模变结构控制的复合谐波电流控制算法,这两种算法均采用S函数来构建,通过了Matlab仿真验证,并应用在系统样机中。实验结果表明,新型HAPF的性能大大提高且能够达到改善煤矿电网电能质量的要求。A novel active power filter is proposed with the advantages such as large capacity,low-cost and low-loss.On the harmonic current compensation aspect,the system prototype test the discrete fourier transform（DFT） ;On the har monic current compensation aspect,a combined harmonic control al-gorithm is put out,which is combined with re cursive integral PI algorithm and sliding-mode control algorithm.The two algorithms are adopting S function to con struet.Finally,through Matlab simulation model establishment and used in system prototype ,the experiments show that the performance of the hybrid active power filter and grid power factor are greatly improved, and can meet require ment of improving power quality in coal mine.
