摘要
Abstract
The cascade static synchronous compensator (STATCOM) with delta configuration is usually used to compensate negative sequence currents, and its reference value of circulating currents determines the stabilization of the capacitor voltages.Based on a comprehensive analysis of the current relationship of the cascade STATCOM with delta configuration, the negative sequence current components as well as active power of the bridge arms, the reference value can be mutually produced by the bridge arm capacitor voltage balancing control, load current negative sequence component and system line-to-line voltage phase angle.The simulation results by MATLAB/Simulink prove the feasibility and effectiveness of the control method by using this mutually produced reference values for the cascade STATCOM with delta configuration.关键词
