Abstract :
The circuit of DSTATCOM is analyzed. The dynamic model of DSTATCOM based on three-level voltage inverter is established by way of lead-in switch function. Control method of DSTATCOM is focal point of this research. The dissertation determines the detection means based on instantaneous reactive power. PWM control by tracking the current technology achieve to direct control. The simulating results prove the DSTATCOM put forward in the dissertation can realize dynamic var compensation effectively.
