摘要
电力电子技术的迅猛发展给人们带来方便的同时,也给电网注入了大量的谐波,污染了电网。为了提高电网质量,人们越来越关注谐波的检测与抑制方法。本文采用瞬时无功功率理论的ip-iq算法,并在算法仿真的基础上,以CPLD和DSP为平台,重点研究了实时、准确的检测电网谐波电流的理论方法与软硬件实现,实际应用结果表明该方法能够满足电网谐波检测的实时性、准确性要求。
The rapid development of power electronics injected unexpected harmonic into public power network,which polluted the power network,when it brought much convenience to life.In order to improve the power quality,more and more attention has been paid to harmonic detecting and restraining.This paper studies mainly on accurate detection of harmonic currency in real time,by means of instantaneous reactive power theory,based on DSP and CPLD,and the simulation of ip-iq algorithm.The results show that the method is suitable for harmonic detection in real time accurately.
