Predictive Current Control of Distribution Static Condenser (D-STATCON) for Reactive Power Compensation in Flexible AC Transmission System(FACTS)

유연송전시스템에서의 역률 보상을 위한 배전용 정지형 동기조상기의 전류제어

This paper describes a modeling and current control techniques of Distribution static condenser (D-STATCON) for power factor compensation. The current control is based on the predictive and the space vector PWM scheme. The predictive current controlled PWM D-STATCON can maintain its performance with power factor compensation and fixed switching frequency. By using the space vector control low ripple and offset in the current and the voltage as well as fast dynamic responses are achieved with a small DC link capacitance employed.
