Research On The Monitoring System Of Configuration Active Power Filter

This paper based on the current technology of harmonic restraining and VARoffsetting, presents configurations of APF with PPF or capacitors to solve theproblems of harmonic and VAR consumption. The paper introduces theconfigurations of APF with PPF or VAR, analyses the principle and main circuit ofthese configurations, compares the methods of current detections in theseconfigurations, and analyses the compensating characters and stability of theseconfigurations. The paper made a suit of monitoring system of HAPF in order tokeep the stability and reliability of HAPF, The monitoring system could make theoperation of HAPF more easily, and monitor the HAPF efficiently through a seriesof practical testing,The whole project attains the designing aim.
