摘　　要：针对越来越严重的电网谐波污染问题,提出了基于混合有源滤波器的解决方案——电网谐波分析与治理一体化系统。介绍了其结构、原理和功能,重点阐述了谐波的检测与分析、系统控制信号产生等内容。实验表明,系统对各电量的检测误差均小于2％,电网三相电压总畸变率和电流总畸变率均大幅下降。电网谐波分析与治理一体化系统对于有效治理谐波、净化电气环境以及电网的科学化管理具有积极意义。Harmonic analysis and elimination system based on hybrid active power filter is proposed in this article to solve the serious problem oi harmonic pollution in power grid. The harmonic analysis software and the generation method of control signals of hybrid active power filter are introduced. The experimental results show that the detection error is less than 2% , the THDs of voltage and current of three phases have been greatly reduced.
