摘要
变频器的大量应用,使得供电电网的电流谐波污染变得较为严重,加重了电网中供电变压器的发热,电容器及电力电缆等设备的运行损耗随之增加。针对电流谐波带来的危害,利用有源电力滤波器对供电电网的电流谐波加以治理,既消除了电网的污染,又做到了节能降耗。介绍了滤波治理的基本原理及节能降耗的结果。
Because of the wide application of inverters, not only the current harmonic of power net becomes more and more serious,but also many equipments, such as transformers,capacitors,cables and etc,wasts lots of energy.In allusion to the dangers of harmonic ,Active Power Filter （APF） is widely used to reduce the harm of current harmonics.It not only eliminates the harmonic pollution on net but also reduces the waste of energy.In this paper,the definition,dangers of harmonic in power system are introduced, and the principle and result of the APF are introduced.
