Simulation of STATCOM Effect on the Dynamic Response Performance of HVDC

The transient mathematical model for the STATCOM is developed in d-q coordinates in this paper. It constructs a pseudolinear system of STATCOM, using the inverse system method which based on the nonlinear feedback linearization theory. Then, by synthesizing the pseudolinear system, a sliding mode variable structure controller is designed. This article focuses on the effect of dynamic response performance of the HVDC system failure, when using different reactive power compensation devices such as SVC and STATCOM, etc. It also compares STATCOM with conventional PI control with STATCOM with variable structure control. The simulation results indicate that the designed controller can enhance the static and dynamic performance of HVDC system failure better.
