Basing on the double closed loop control method of the Static Synchronous Compensator's performance improvement and simulation

This paper introduces the Static Synchronous Compensator, which installed in distribution network is generally called D-STATCOM. Firstly, we present the Structure chart of D-STATCOM. Then the control strategy were studied in the double Closed-Loop, we analyse the Mathematical model of three-phase voltage source rectifier, and the control Strategy. At last, the scenarios of time-varying power sourcer and modulation of the variable load are considerd in simulation investigations. The simulation results demonstrace that the control strategy applied ensures obvious dynamic and steady stage performance.
