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.
