本文在分析抑制谐波常用方法的基础上 ,利用瞬时无功功率理论进行有源滤波器的仿真设计。该方法可以实现快速的高次谐波检测与滤波 ,并进行无功功率补偿。本设计用先进的仿真软件工具 MATLAB中的电力系统仿真工具箱对基于这种方法的有源滤波器进行仿真 ,仿真结果表明基于瞬时无功功率理论设计的有源滤波器装置能够有效检测出高次谐波分量 。

Based on analyzing the common way of harmonic restraint,this paper makes use of the theory of instantaneous reactive power to simulate and design active power filter.We use MATLAB,which is a simulation tool for power system,to simulate active power filter.Experimental result confirms that the device active power filter can inspect the higher harmonic component and reactive power immediately.
