Optimization for Tokamak Reactive Power Compensation and Filtering System

The study of Tokamak reactive power compensation and harmonic filtering (RPC&HF) is of great significance for stable operation of electric power system and future nuclear fusion power station. Considering converter load’s features, performance and cost sufficiently, thyristor controlled reactor and fixed capacitor (TCR + FC) is recommended, which aims to solve long response time and low compensation precision with traditional methods of compensation and filtering in Tokamak. In this paper, filter branch and thyristor controlled reactor are optimized. Focusing on converter characteristics, the method of predictive reactive power–voltage feedback composite control is emphatically put forward. The shorter response time, better compensation and filter effect achieve expected effect in RPC&HF System II of EAST.
