Harmonic Magnification Mechanism and Suppression Method of Filter in Isolated Network System
摘要
Abstract
The general structure of the isolated network with rectifier load was analyzed. Harmonic amplification mechanism of the filter and the generator in this type of isolated network system was analyzed from three aspects:the equivalent circuit of harmonic amplification,the frequency drop of the isolated network and the frequency fluctuation. Starting with the mechanism of harmonic amplification,the regulation characteristics of the generator speed regulation system were studied. According to harmonic amplification frequency condition,the harmonic amplification suppression mode based on the optimization of filtering parameters and the speed of load increase was proposed,which had the advantages of simple and flexible. The correctness of the harmonic amplification mechanism of the isolated network and the effectiveness of the suppression strategy were verified by a ice-melting experiment.关键词
