有源電力濾波的拓撲結(jié)構(gòu)與檢測控制策略

摘　要:各類大功率非線性、時變性負荷的廣泛應(yīng)用,使電網(wǎng)的諧波污染問題日益嚴(yán)重,電能的質(zhì)量受到很大的影響,而且注入電網(wǎng)中諧波的性質(zhì)不盡相同,為了對諧波源采取有效的抑制措施,降低造價、減少損耗、提高補償效果,針對APF拓撲結(jié)構(gòu)和檢測控制策略等關(guān)鍵技術(shù)的工程應(yīng)用特性進行了研究分析,提出了優(yōu)選方案.

關(guān)鍵詞:諧波;抑制;結(jié)構(gòu);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.
