摘要
基于SPWM原理,推导了水轮机组励磁、调速系统与超级电容储能电气制动装置(Super Capacitor energy storage Brake Device,SCBD)的非线性微分代数模型,采用多指标非线性控制(Differential Algebraic Multiindex Nonlinear Control,DAMNC)法设计综合控制器。论述了输出函数的选取原则,并通过适当配置输出函数参数矩阵,使得非线性综合系统的特征根满足稳定的要求,从而使系统具备良好的控制性能。仿真结果表明:所设计的控制器能够很好地协调系统的动、静态性能,对改善系统的暂态稳定性效果显著。
Based on the principle of SPWM, the nonlinear Differential Algebraic Multi-index Nonlinear coordinate Control(DAMNC) law of the excitation, speed regulation system of the hydro-turbine unit and Super Capacitor energy storage Brake Device(SCBD) is designed.The selection basis of the output function is given. By properly configuring the output function parameter matrix, the characteristic roots of the nonlinear integrated system can meet the requirements of stability, so that the system has good control performance. The simulation results show that the designed controller can coordinate the dynamic and static performance of the system well, and has a significant effect on improving the transient stability of the system.
