摘要

参考电流在电能质量控制算法中起着决定性的作用。本文介绍了六种时域参考电流提取方法的原理，并应用MATLAB/Simulink软件对八种工况进行了仿真。结果表明，p-q理论方法具有高功率因数(PF)三相平衡和谐波抑制作用;Fryze-Buchholz-Depenbrock(FBD)方法反应性强，谐波大;延迟信号对消(DSC)方法对源电压和负载影响较小;单位功率因数(UPF)法适用于源电压，且PF = 1;完全谐波对消(PHC)方法有较大的超调量，在稳态方法上优于ip-iq方法。本文的研究结果为电能质量控制器件的设计和控制算法提供了依据。

Research of several reference current extracting methods in time domain

Reference current play a decisive role in power quality control algorithm. In this paper, introduce the principle of six reference current extracting methods in time domain, and applying MATLAB/Simulink software to simulate in eight conditions. The results shown that p-q theory method have a high power factor(PF) three-phase balance and harmonic suppression; Fryze-Buchholz-Depenbrock(FBD) method have large reactive and harmonic; delayed signal cancellation (DSC) method have little source voltage and load influence; unity power factor (UPF) method follow with source voltage well, and PF equal 1; perfect harmonic cancellation (PHC) method have large overshoot, in steady state approach to ip-iq method. The results of this paper provide the basis for power quality control devices design and control algorithm.
