The design of nonlinear control strategy for SSSC based on constant voltage control

Static-synchronous-series-compensator has a broad prospect of a controllable series compensation technology which can improve the performance of power system, arousing increasing attention, this paper from the angles of constant voltage control of SSSC analyzes its characteristic, then the three-order mathematical model is established in reference to the single machine infinite bus system with SSSC. The theory of inverse system and sliding mode control are used for the design of control strategy for multi-order nonlinear systems. Finial, the results of MATLAB prove the viability and robustness of the SSSC control strategy.
