Abstract
In order to solve the capacitor voltage balance problem of cascade STATCOM , a voltage balancing control method based on single-carrier modulation is probed in this paper ..Aiming at the single-carrier modulation cascade STATCOM, the voltage decoupling control method is adopted to realize the control of overall active power .In terms of the voltage balancing control , a voltage balancing control strategy which combines the energy exchange method with circulation transposition method is proposed to realize the voltage dynamic balance process and improve the steady state balance precision at the same time .A switch control method is proposed to realize reliable switching of working mode.Finally, the effectiveness and feasibility of the proposed control method are verified by the simulation results .关键词
