Aimed at the voltage problems such as voltage sags in the wind power station, distribution static synchronous compensator （D-STATCOM） is applied. The paper introduces the structure of D-STATCOM which is applied to a wind power station and presents a design scheme of D-STATCOM controller. At the same time, designs of software and hardware of D-STATCOM are proposed in this paper. Taking DSP as the core of the controller, the speed of operation and the precision of control are improved. Experimental results show that the design of D-STATCOM controller is of excellent performance of control and practicability and has a good prospect in engineering application.
