重点介绍了主电路的设计方案、工作原理,并利用Matlab仿真平台,对装置进行了仿真分析。结果表明,该装置克服了传统有源电力滤波器功能单一的局限,使有源电力滤波器在进行谐波和无功补偿的同时还可以解决电压跌落、短时停电等多种电能质量问题。
The design scheme and working principle of the main circuit are introduced emphatically, and the simulation of the device is carried out by using Matlab simulation platform. The results show that the device overcomes the single limitation of the traditional active power filter and makes the active power filter not only compensate for harmonics and reactive power, but also solve various power quality problems such as voltage sag and short-time power outage.
