| 摘要: |
| 建立了考虑涡轮入口和出口容积效应的涡轮动力学模型，利用该模型计算了燃气涡轮气瓶启动的动态响应过程，分析了影响涡轮动态特性的主要因素。计算结果表明：涡轮前容积对涡轮入口压力和出口背压的过渡过程均有显著的影响，涡轮后容积对涡轮入口压力的过渡过程影响不大，对涡轮出口背压的影响显著。 |

| Abstract: |
| A dynamic model of gas turbine, which takes both before-turbine and post-turbine capacity into consideration, is developed. The dynamic behavior of gas turbines in start-up by high-pressure gas is calculated by using the model, and its principal influence factors are analyzed. The calculated results show that the before-turbine capacity has notable influence on the transients of both entrance and exit pressures of the gas turbines, the post-turbine capacity mostly affects the dynamic processes of the turbines' exit pressures, and has little influence on the turbines' entrance pressures. |
