摘　　要：燃气轮机实时动态优化问题,是燃气轮机控制系统校核的重要依据,目前通常采用传递函数模型,无法了解燃气轮机内部各参量的动态相互作用机理。针对实时非迭代建模的要求,利用容积惯性思想建立了燃气轮机模块化仿真模型库;在Matlab/Simulink仿真平台上搭建了某重型燃气轮机系统仿真模型,对动态特性进行了分析,并针对燃气轮机的转速调节和负荷控制建立了控制器模型,进行了初步仿真研究;考虑到燃气轮机的使用寿命以及安全性等,将排气温度限制加入燃气轮机控制环节,比较出系统控制性能,实现了燃气轮机控制系统的参数选择,从而为燃气轮机的控制系统设计提供参考和依据。The real time simulation model is the key point for the debug and checking of the controller for gas tur-bine engine. The conventional transfer function model can not reflect the interaction among different variables. Ac-cording to the volume inertia method and object-oriented technique, one nonlinear dynamic model of V94.3 gas tur-bines was built up based on Matlab/Simulink simulation platform and the dynamic characteristics were analyzed. In the light of the gas turbine speed regulation and load control, the controller module was established. Simulations were eventually performed for control performance, which can supply references to the design of control system of V94.3 gas turbine.
