摘　　要：基于单机无穷大系统,建立了静止同步补偿器(static synchronous compensator,STATCOM)的数学模型,设计了变结构协调控制器。采用直接反馈对系统进行全局线性化,运用变结构控制方法,设计了STATCOM无功电流与发电机励磁、汽轮机调门的非线性滑模协调控制器,可以同时满足发电机励磁、汽机调门与STATCOM装设处电压稳定要求。对单机—无穷大系统进行了数字仿真,结果表明控制器能有效改善系统稳定性。A mathematic model of static synchronous compensator （STATCOM） as well as a controller using nonlinear variable structure control strategy is presented in the paper based on a one-machine infinite bus system. The system was global linear by using direct feedhaek linearization and the controller for the reactive current of STATCOM and the generator excitation, steam-valving system was designed by variable structure control method, which can meet the requirement of stability of generator power angle and that of STATCOM voltage. Numerical simulation of one machine-infinite bus system shows that the controller is effective and advantageous.
