Abstract :
A delta-connected static synchronous compensator (STATCOM) is proposed for real-time load compensation of unbalanced load. The structure of the STATCOM is a multilevel cascaded full H-bridge inverter which is suitable for high-voltage, high-power applications. First, use of the symmetrical components method derives the control algorithm of the STATCOM. The STATCOM is then built in the Matlab/Simulink environment. Finally, simulation results indicate that the proposed delta-connected STATCOM is effective for real-time load compensation of unbalanced loads.
