DC Capacitor Voltage Balancing Control for Cascaded STATCOM

Abstract:

Through the DC side capacitor voltage unbalance problem of cascaded static synchronous compensator. Put through a theory of active voltage average distribution to balance DC capacitor voltage, using master slave controller to realize controlling requirements. The main controller calculates each phase AC side of H bridge required total active and reactive voltage and grid voltage phase information etc, The slave controller complete each cascade module for active voltage average distribution control. The simulation results show that the method is feasible and effective.
