Given a new type of reactive current feedback control algorithm based on the DC bus voltage control and system control of Static Var Compensator (STATCOM), the three kinds of wind speed gradient , random gust , for example STATCOM the pensation characteristics of the simulation analysis, and pensation effect and the thyristor switched capacitor (TSC) were pared . The simulation results show that pared with TSC , STATCOM in the pensation process can be quickly and stable tracking of reactive changes and no significant impact of voltage and current pensation .
