摘　　要：对于热电联产机组而言,在电力现货市场环境下,当供电需求旺盛时,上网电价的增益是一笔不小的收益,但供热价格一般不随供热量的增加而上涨。当电价涨到一定程度时,可考虑利用启动锅炉等其他方式减少机组供热量,以增加机组上网电量,提升机组盈利能力。通过分析天然气价格、上网电价以及启动成本,找出燃气-蒸汽联合循环热电联产电厂利用启动锅炉辅助供热运行模式的边际收益点,可增加热电联产电厂的收益。For cogeneration units,in the electricity spot market environment,when there is a strong demand for power supply,the gain in grid electricity prices is a significant benefit,but heating prices generally do not increase with the increase of heating volume.When the electricity price rises to a certain extent,other methods such as starting a boiler can be considered to reduce the heat supply of the unit,increase the grid power of the unit,and improve the profitability of the unit.By analyzing natural gas prices,grid electricity prices,and start-up costs,we can identify the marginal revenue points of gas steam combined cycle cogeneration power plants using start-up boiler assisted heating operation mode,which can increase the revenue of cogeneration power plants.
