The study of magnetic confinement fusion device TCR-SVC system has importance significance for the stable operation of regional power supply grid and the construction of future fusion substation. As for such problem of traditional compensation and filtering method for the fusion as long response time and low filtering and compensation accuracy

in this paper

related parameters of the filtering branch

phase-control reactor and thyristor valve are optimized and designed. Reactive power prediction-voltage feedback composite control method is proposed emphatically for the particularity of load. It is shown that response

compensation and filtering performance of reactive power compensation and filteringⅡ phase project for EAST reach good expected result.
