【摘要】 由于电力电子技术在电力系统中的大量应用,使得电力系统中的电流电压波形畸变越来越严重。文章首先对电力系统谐波的来源、危害和检测做了简单的介绍,然后详细阐述了利用有源滤波器进行谐波抑制的方法,并有相应的电路和matlab仿真波形。更多还原

【Abstract】 because of a great deal of power electronic technology in power system, the aberration of voltage and current wave become more and more severe. In this paper ,the source and harm of power system harmonic and its detecting technolo gies are briefly introduced firstly,then a method that harmonic restraining that making use of APF is recommended in detail , finally corresponding electrocircu it and simulation made by matlab are given.更多还原
