电力系统信号采集与谐波测量方法

Signal acquisition and measurement methods for harmonics in power systems

电力参数监测是电力系统中最基本的计算之一,对指导电力系统安全、经济和可靠运行起着关键的作用。本文回顾了近二十年来电力参数算法的发展进程,介绍了信号采样方法并作了简要比较和评述。对于谐波检测方法的发展方向,本文亦作了一些探讨。

The measurement of power parameters is one of the most basic calculation in power systems and plays a key role on running power systems in security,economy and reliability.This paper reviewed the development of algorithm of power parameters in recent twenty years,introduced the sampling algorithms of signal and gave brief comparison and comment.The new trend of the development of harmonic measurement was also discussed in this paper.
