摘要
在电厂供电系统中，电力变流器和其它非负载向系统中“注入”谐波电流，引起一系列问题．本文讨论各种谐波问题，如供电电压畸变，功率因数降低，增加能量损耗，干扰通信系统等，并对解决谐波问题的各种方法，如增加整流器相数，正确配制电力电容器组，注入谐波电流和使用滤波器进行了探讨．
The power converters and other nonlinear load inject the harmonicscurrent into the power system and cause a series of problems. The harmonic problem,such as distorting supply uoltage,deereasing opwer facter, increasing energg loss,interfering with comunication system are discussed in first. The next pert discusses the solutions to the harmonic problems,including increasing converter phau,setting up new capaciter hank or relocating the existing one,injecting harmonic current and using shut filters
