摘　　要：从静止同步补偿器(static synchronous compensator,STATCOM)的内部结构入手,选用STATCOM的脉冲控制角??和STATCOM超前系统电压角???为控制量,提出一种新型的STATCOM控制模型,可有效克服以往STATCOM模型需假设强约束条件的缺点。基于微分代数系统,结合多指标非线性控制(multi-index nonlinear control,MNC)设计理念,完成STATCOM与凸极式发电机励磁的协调控制策略的设计,并通过单机无穷大系统对其进行暂态仿真。仿真结果同线性最优控制法进行对比,表明本文所设计的6阶协调控制模型是合理而有效的;利用MNC法设计的协调控制策略能有效提升系统的动、静态性能。In order to overcome the previous static synchronous compensator （STATCOM） model＇s strong constraints conditions, this paper established a new type of control model for STATCOM by Using the STATCOM＇s impulse control angle 0 and its advanced system bus voltage angle a as the control variables. The six-order nonlinear differential algebraic system （DAS） mathematical model was set up for the single machine infinite bus （SMIB） system which includes a STATCOM and a salient-pole generator excitation model Based on this DAS model, the coordinated controller was designed using multi-index nonlinear control （MNC） method. The simulation results show that the new coordination control method and nonlinear control law u presented in this paper can improve the power system＇s dynamic and steady-state performances which are more effectively than linear optimal control （LOC）.
