基于改进型瞬时无功功率的有源电力滤波器的研究

Instantaneous Reactive Power Based on Improved Active Power Filter

供电系统谐波电流电压的出现对电网是一种污染,使得电力设备的工作环境恶化,对电网进行谐波治理迫在眉睫。使用一种改进的瞬时无功功率检测谐波的方法快速检测谐波电流,使用PSCAD/EMTDC建立了一个关于对三相整流电路谐波治理的动态模型,仿真结果显示达到了良好的补偿效果。

The emergence of current and voltage harmonics on the grid is a kind of pollution,which making the work of environmental degradation,on the power network harmonic treatment is necessary.This paper uses a modified instantaneous reactive power detection method for rapid detection harmonic harmonic current,Using PSCAD / EMTDC set up a harmonic treatment of the dynamic model,simulation results show that the compensation to achieve good results.
