Abstract：In the control of voltage source PWM converter, direct power control based on space vector PWM(DPC-SVM) has become research hotspots. For the generic DPC-SVM method, the transmission speed of transient active power is different between the two sides of converter . When the load varies fast and hugely, the unbalanced power can make the DC voltage rise up . This problem will damage equipment and cause loss. By analyzing the factors which influence the fast transient response, this paper concludes the relationship between power transient response rate and system parameter, then puts forward a new control scheme to improve power transient response rate by utilizing the reactive power in transient state. Simulation results show that the proposed control scheme has satisfactory steady-state characteristics and fast transient response. This control scheme possesses some practical values due to its simple implement.
