摘要
在现代电力系统中,由于电力电子技术的广泛应用,谐波污染问题越来越严重。谐波检测是谐波问题中的一个重要分支,是解决谐波问题的基础。介绍了几种主要的谐波检测方法,分析比较了各种方法的特性,并分析了谐波检测的发展趋势。
With the development of the power electronic technique, the pollution of harmonic wave has become more and more serious in modern power system. The harmonic detection is a very important part of this field, and also is a basic for solving harmonic wave problem. Several kinds of methods to harmonic detection are introduced in this paper. And the features of the methods are analyzed and compared. In addition, the development trend of the harmonic detection is analyzed.
