摘要
有源电力滤波器(APF)是补偿电力系统谐波及无功功率的重要装置,有效的谐波检测方法和控制方法,将大大改善电力系统高次谐波污染,提高电网的供电质量。文章分别介绍了有源电力滤波器的谐波检测方法和有源电力滤波器的控制方法,阐述了这些方法在APF中的应用情况,并指出有源滤波器目前存在的问题。
The active power filter is an important equipment of compensated electric power system harmonic and reactive power, the effective detecting method of harmonic and control method will comparatively improve the higher harmonic wave pollution of power system. The paper introduces the detecting method of the active power filter harmonic wave and its control method application situation in active power filter, as well as points out the existing problem of active power filter.
