摘　　要：随着燃气轮机性能的不断提高 ,其应用范围也越来越广。除用在燃气轮机电站及联合循环电站中外 ,同时也越来越多地用作变转速的机械驱动动力。本文给出了作为机械驱动动力的单轴燃气轮机及其控制系统模型 ,结合实际情况对其进行了简化 ,并在Matlab/Simulink环境下对升减负荷、升减转速以及甩负荷过程进行了模拟。模拟结果与实际物理过程相吻合 ,因此 ,此模型可以用于单轴燃气轮机及其控制系统的研究。With the continuous improvement in gas turbine performance its scope of applications is widening dramatically. Apart from its use in power generating units and combined cycle power plants there emerged ever more cases of its application as a variable-speed mechanical drive unit. Presented in this paper is a model of single-shaft gas turbine in mechanical drive service including its control system. The model has been simplified in light of specific conditions. Under a Matlab/Simulink environment a simulation was conducted of the process of load and speed increase-decrease as well as load rejection. The results of simulation agree quite well with actual physical processes. Hence, the proposed model can be employed for the study of a single-shaft gas turbine and its control system.
