Design of nonlinear integrated controller for single-machine-infinite-bus system with static-synchronous-series-compensator
含静止同步串联补偿器的单机系统非线性综合控制器设计

For the interactions between the single-machine-infinite-bus system with static-synchronous-seriescompensator, the excitation and the stream valve control, we develop a 4th order nonlinear model with three inputs and three outputs. This model is decoupled and linearized by using the dynamic inverse system theory to obtain three SISO pseudo linear systems; with them we design three SISO controllers by using the variable structure control theory. Simulation results on MATLAB show the feasibility and effectiveness of this control strategy in stabilizing the power-angle, the generator terminal voltage and the transmission power.
