| 摘 要： | 湿空气透平(Humid air turbine,HAT)循环是当今最先进的燃气轮机循环之一,饱和器水温控制是HAT循环一种通过改变饱和器给水量维持进口水温的控制逻辑。基于上海交通大学HAT循环实验台建立HAT循环模型,分析饱和器水温控制对HAT循环系统稳态和动态性能的影响。仿真结果表明,饱和器水温控制可以提高系统变工况运行的效率。对于研究对象,系统效率在75%工况条件下提高0.071%。此外饱和器水温控制可以使得饱和器更快达到稳定,但对HAT循环系统功率调节特性的影响较小。

| Abstract: | Humid air turbine (HAT) cycle is one of the most advanced gas turbine cycles. Saturator water temperature control is a control strategy that adjusts the water flow rate to keep the outlet temperature at the designed value. A HAT cycle model based on the HAT cycle test rig of Shanghai Jiao Tong University is built to analyze the influence of water temperature control on both steady-state and dynamic performance of HAT cycle system. The simulation results show that system efficiency increases by 0.071% for the study object on 75% load. The dynamic response of output power changes little, while the saturator can achieve stable faster. |
