Abstract :
A control method for SVPWM-based static synchronous compensator (STATCOM) using active-reactive current decouple under dq coordinate system is proposed. STATCOM with active-reactive current decouple based on dq coordinate system can precisely and quickly follow the reference current. It can lower switching frequency, enhance DC voltage utilization by proposing SVPWM. A simulation model based on this method is built in the Matlab platform. The simulation results show that, the proposed control method can make sure STATCOM precisely and quickly compensate reactive power, improve the power factor, stabilize the DC voltage. It has excellent dynamic and steady-state characteristics.
