电力系统谐波检测技术的现状与发展趋势

摘要

Harmonic test plays an important role and function in traction power supply system. Based on the basic requirements of power system＇s harmonic test, analysis and appraisal were made to harmonic measurement methods both at home and abroad. It is pointed out that under asynchronous sampling conditions, the new method to realize non-linear circuit dynamic harmonic analysis and harmonic electric energy measurement is the new requirements for power system＇s harmonic test technology development. Mu- tual combination and coordination of harmonic test, harmonic analysis and harmonic treatment, measurement and control integration, intelligentizing and on-line harmonic measurement have become new harmonic study trend.%在牵引供电系统中谐波检测具有重要的地位和作用,根据电力系统谐波检测的基本要求,对国内外谐波测量的方法进行了分析和评述,指出在非同步采样条件下实现非线性电路动态谐波分析与谐波电能计量的新方法是电力系统谐波测量技术发展的新要求;谐波测量、谐波分析、谐波治理相互结合与配合,测量与控制集成化、一体化、智能化以及在线谐波测量已成为谐波研究新趋势。
