摘　　要：通过建立高温气冷堆氦气轮机各部件的集总参数数学模型,利用Matlab/Simulink仿真软件构建仿真模型,对氦气轮机起动过程的瞬态运行特性进行了仿真研究,给出了高、低压压气机运行线以及压气机出口压力、堆芯进出口温度、涡轮功率、压气机功率、发电机功率等主要参数随堆芯功率的变化曲线。模拟计算结果表明,在氦气轮机起动过程中,主要参数曲线变化趋势与设计要求一致,瞬态特性的仿真结果合理、可信。By setting up the lumped parameter mathematic models of HTGR helium gas turbine and compressor device,and using Matlab/Simulink to build the simulation models,the transient operation characteristics of startup process of helium gas turbine were studied.The simulation results give the operation curves for high pressure compressor,low pressure compressor,and some key curves of compressor outlet pressure,core inlet and outlet temperature,turbine power,compressor power and generator power changing with core power.The calculation results show that,in the startup process,the trends of these main parameter curves meet the design requirements,and the transient characteristics simulation results are reasonable.
