中间再热式汽轮发电机组的多指标非线性综合控制器的研究

STUDY ON MULTI-INDEX NONLINEAR INTEGRATED CONTROLLER FOR REHEAT-TYPE TURBOGENERATOR UNIT

采用多指标非线性控制设计方法,对中间再热式汽轮发电机的高、中压缸以及励磁控制系统进行综合考虑,并计及中间再热器的动态过程,设计了一种大型汽轮发电机的多指标非线性综合控制器。仿真结果表明,该控制器能很好地兼顾受控系统多个状态量的响应特性,协调系统的动、静态特性,并使发电机具有满意的输出特性。

Using multi-index nonlinear integrated control theory, the high pressure valve, and the intermediate pressure valve and the excitation control are considered in a unified nonlinear frame, the dynamic process of the intermediate superheater is also taken into account. A multi-index nonlinear integrated controller for high power turbogenerator has been designed. The simulation results show that this controller can give consideration to the response characteristics of many state variables in the controlled system at the same time and can coordinate the dynamic and static characteristics of the system, and give the generator a satisfied output characteristic.
