为了提升三轴燃气轮机动态性能仿真分析效果，提出大型船舶发电用三轴燃气轮机动态性能仿真方法。计算大型船舶发电用三轴燃气轮机涡轮动态特性，以Simulink为开发工具，获取能够在计算机内运行的三轴燃气轮机动态性能仿真模型，仿真分析其动态性能。经过稳态分析可知，该方法在不同工况下获取的数据误差较小，均控制在5%以内，说明该方法构建的三轴燃气轮机动态性能仿真模型准确性较高；在负载连续突卸状况下，三轴燃气轮机的高低压压气机流量与高低压转子转速均呈梯度下降趋势；负载突卸时，燃油流量也迅速下降，负载稳定时，经过燃油控制器处理后，燃油流量略有上升趋势。
The dynamic performance simulation analysis effect of three-axis gas turbine is improved, and the dynamic performance simulation method of three-axis gas turbine for large ship power generation is proposed. The dynamic characteristics of three-axis gas turbine for power generation of large ships are calculated. Using Simulink as the development tool, the dynamic performance simulation model of three-axis gas turbine which can run in the computer is obtained, and its dynamic performance is simulated and analyzed. Through steady-state analysis, the data errors obtained by this method under different working conditions are small, all of which are controlled within 5%, which shows that the dynamic performance simulation model of three-axis gas turbine constructed by this method is accurate. Under the condition of continuous sudden load discharge, the flow rate of high and low pressure compressor and the speed of high and low pressure rotor of three-axis gas turbine show a gradient downward trend. When the load is suddenly unloaded, the fuel flow decreases rapidly, and when the load is stable, the fuel flow increases slightly after being processed by the fuel controller.
