The variety energy work topology structure of the modern power system puts forward higher requirements for the safe and stable operation of the power grid. ing of the Flexible AC Transmission System (FACTS) solved the problems of improving the transmission lines’ capacity and strengthening the stability of the power system. Static Synchronous pensator (SSSC), as the one of the most prospect application pensator member of FACTS, which is added a controlled voltage source to the transmission line by the voltage type converter, could improves the transmission power of lines, suppressions the system power oscillation and guarantees the safe and stable operation of power system. pensation characteristic of SSSC to system is determined by its internal controller, whose output performance directly affects pensation of SSSC. In addition, as more and more FACTS equipment put into operation to the grid, which is bound to cause more interaction among FACTS controllers that would endanger the safe and stable operation of power system. Therefore, it is a practical engineering significance research work to investigation the interaction between FACTS device and coordinate control their controller from the global system. To solve the control strategy of SSSC, a coordinate controller consisted of SSSC and generator excitation model was given in this paper. The nonlinear dynamic model of SSSC was formed by its basic structural features and operation principle. The controller was based on a single machine infinite bus power system and
