摘　　要：天然气冷热三联供项目运行的经济性受天然气价格、电价等多种因素的影响,由于天然气价格一般执行固定单价,而电价执行峰谷平电价,所以不同电价时段三联供项目的盈利能力不同。当天然气价格一定、电价低到一定程度时,三联供项目可能不仅不能盈利,反而亏损。因此有必要确定一个盈亏平衡电价,以方便地指导天然气冷热电三联供项目运行,确定项目最经济的运行模式。The economics of natural gas combined cooling,heating,and power(CCHP)project is affected by natural gas prices,electricity prices,and many other factors.Since the price of natural gas generally adopts a fixed unit price,and the price of electricity adopts the peak-to-valley price,the profitability of the CCHP project is different in different electricity price periods.When the price of natural gas is fixed and the price of electricity is low to a certain extent,the CCHP project may not only fail to make a profit,but lose money.Therefore,it is necessary to determine a break-even electricity price to guide the operation of the CCHP project and determine the most economical operation mode for the project.
