摘要
近年,供电网谐波污染问题逐步成为关注的焦点。介绍了工业、商业和市政服务领域的典型非线性负载的谐波特性,建立电路模型,分析其工作原理,并利用仿真软件给出各种非线性负载输入侧电流波形及其频谱分析。结合现场调研测试,总结评估了典型非线性负载的谐波特性,并给出谐波治理的有效方案。
In recent years,harmonic pollution issues gradually become the focus of attention in power supply network.The harmonic characteristics of the typical nonlinear loads in industrial,commercial and municipal service fields are introduced.This paper establishes the circuit models and analyzes the working principles of nonlinear loads in detail.The input current waveforms of various nonlinear loads and their spectrum analysis are also given using the simulation software.Based on the site investigation and testing,summary and evaluation of the harmonic characteristics of typical nonlinear loads,and the effective solutions of harmonic elimination are presented.
