有源电力滤波的拓扑结构与检测控制策略

摘　要:各类大功率非线性、时变性负荷的广泛应用,使电网的谐波污染问题日益严重,电能的质量受到很大的影响,而且注入电网中谐波的性质不尽相同,为了对谐波源采取有效的抑制措施,降低造价、减少损耗、提高补偿效果,针对APF拓扑结构和检测控制策略等关键威廉希尔官方网站 的工程应用特性进行了研究分析,提出了优选方案.

关键词:谐波;抑制;结构;策略

Abstract :The application of every kind of high efficiency non2linearity with denatured load causes the overtone pollution of electrical network day by day , resulting in the tremendous bad influence on electrical energy quality because of the different nature of overtone
poured into the electrical network. In order to take effective suppression measures to the overtone sources , to reduce the construction cost and the reduction loses , to enhance compensation effect , the essay analyzes about the key technical characteristic in the view of
APF topology and examining control strategy and proposes the optimal plan.
