Abstract

Capacitor voltage balancing is indispensable in normal operation for modular multilevel cascade converter- single star bridge cell (MMCC-SSBC) based static synchronous compensator (STATCOM). This paper proposes a novel individual voltage balancing scheme with dramatically reduced voltage sensors. First, zero-sequence voltage injection is enabled to regulate the cluster voltage based on only one voltage sensor in each phase; Then, through the additional inserted hardware units, individual voltage balancing can be achieved. Compared with conventional software voltage balancing method, the proposed balancing scheme has the advantage of simple implementation, lower transportation delay, fast balancing speed, and dramatically reduced voltage sensors. In addition, only some popular power modules are added to balance the individual capacitor voltage. The effectiveness of the proposed individual voltage balancing scheme is verified by simulation results in MMCC-SSBC based STATCOM. With the proposed scheme, the individual voltage balancing and reactive power compensation can be realized simultaneously.
