| 摘 要： | 谐波电流对电网的污染日益严重,实时、准确地检测出电网中的谐波电流是谐波抑制和无功功率补偿的一项关键技术.本文对基于单位功率因数的谐波电流检测方法进行了改进,用移动窗积分法取代检测中常用的低通滤波器.使用MATLAB中的电力系统模型库对两种方法建立了仿真模型,并进行了计算机仿真.仿真结果证明,此改进方法原理简单、工程上易于实现,可以有效地改善由低通滤波器产生的检测延时问题,提高谐波电流检测的动态响应速度. |

| Abstract: | The problem of harmonic distortion becomes more serious,accurate and real-time detecting the harmonic of the electric network is very crucial to harmonic restraint and reactive compensation.This paper improved the harmonic current detection method based on UPF(unity power factor),using the slipped window integral to replace the LPF(low pass filter).The two method's simulation model is built in virtue of the Power Systems Blockset in MATLAB.Simulation result shows that the principle of the proposed method is simple easy implement,can efficientively solve delay problem of low pass and improve the dynamic respond speed of the detection. |
