Study of 6kV Chain STATCOM Current Indirect Control Strategy

摘要

STATCOM can achieve the rapid and effective two-way reactive power compensation, which has incomparable advantages of past reactive power compensation modes. Aimed at 6kV grid reactive compensation, this paper establishes input-output model of cascade STATCOM, and improves the traditional indirect control method. The simulation in MATLAB/Simulink environment shows the better control effects of the control method presented by this paper.
