采用高级过程仿真软件APROS(多功能工艺模拟)软件对燃气轮机进行模块化仿真建模,将仿真结果与现场稳态数据进行对比,验证了仿真模型的准确性。以某PG9171E型燃气轮机为研究对象,定量分析了环境条件变化对燃气轮机性能的影响。结果表明:环境温度对燃气轮机的运行特性以及经济性影响较大,标准工况下,环境温度每上升1℃,燃机热耗率上升约0.2%;环境湿度对燃气轮机性能的影响程度会随着环境温度的上升而增加,当环境温度上升到40℃时,相对湿度每增加10%,燃机热耗率会上升约0.12%。
The advanced simulation software APROS (multi-function process simulation) was used to modularize the gas turbine. The simulation results were compared with the steady state data to verify the accuracy of the simulation model. Taking a PG9171E gas turbine as the research object, the influence of the change of environmental conditions on the gas turbine performance was quantitatively analyzed. The results show that ambient temperature has a great influence on the operating characteristics and economy of the gas turbine. The heat rate of the gas turbine increases by about 0.2% for every 1 ℃ ambient temperature increase under standard conditions. The influence of the ambient humidity on the gas turbine performance will vary with As the ambient temperature increases, the engine heat rate increases about 0.12% for every 10% increase in relative humidity when the ambient temperature rises to 40 ° C.
