摘　　要：为提高发电厂的自身竞争力,以前湾电厂M701F燃气—蒸汽联合循环为研究对象,对燃气—蒸汽联合循环机组启停过程的经济损失进行建模计算。通过计算热态、热温态、冷温态、冷态等不同状态启动时的耗气量、耗电量、耗蒸汽量、化学补给水耗量等经济指标及其费用,以及启动过程的发电收益,得到启动过程的净成本。在启动净成本的基础上,计算停机损失与启动多耗时损失,得出政策鼓励下的机组启停过程的经济耗费,形成一个较为完整的经济性分析模型,对同类型电厂有很好的借鉴作用。To improve the competitiveness of power plants, an economic computation module is established based on Qianwan LNG Power Plant M701F gas-steam combined cycle to analyze economic losses during unit start-up and shutdown. There are different states at the start-up process such as thermal state, thermal stable state, cold stable state and cold state. Economic indexes such as gas consumption, power consumption, steam consumption and water consumption under different states at the start-up process are calculated. As the generating incomeat thestart-up process is calculated, thenet cost of thestart-up process is figured out. General expenses caused by shut down and start-up time delay are calculated based on start-up net cost, and economic consumption on unit＇s start-up or shut down are worked out. Then, a complete economy analysis module is established, which contributes to power plants of the same type.
