电力有源滤波器特性研究

Active Power Filter Characteristic Research

随着电力电子技术的不断发展,电力电子装置在电力系统中的应用日益广泛,带来的谐波污染问题也严重的危害着电网的安全稳定运行。目前,无源滤波器是电力系统谐波和无功功率补偿的主要方法,但存在较多不足,有源滤波器具有较好的动态补偿效果,应用前景广泛,基于此,重点进行电力有源滤波器的特性研究。

With the continuous development of power electronic technology, the application of power electronic devices in power system is becoming more and more widely, the harmonic pollution is serious harm to the safe and stable opera- tion of the power grid. At present, the passive filter is electric power system the main method of harmonic and reactive power compensation, but many deficiencies, active filter has good dynamic compensation effect, the application prospect of extensive, based on this, the essay focuses on the characteristics of active power filter.
