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θ和STATCOM超前系统电压角α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 θand its advanced system bus voltage angle αas 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).
