Abstract
Static synchronous series compensator (SSSC) is a facts device that can compensate the reactive power of the line and improve the power oscillation damping. The excitation control is a conventional and significant control for the power system stability. This paper presents a new coordinated control scheme between SSSC and the excitation system of generator. First, three-order nonlinear model of generator and SSSC are established respectively. Then the direct feedback linearization method is used to make the nonlinear model linearized. Finally, the paper applies the optimal control theory to design the coordination controller. The proposed coordination controller shows good performance in damping out power oscillation and has a stronger robustness. The MATLAB simulation results verify the validity of the offered coordinated control scheme.
