摘　　要：以某微燃机为动力的冷热电联产成套系统为研究对象,分别对简单循环和回热循环微燃机进行性能匹配、经济测算和节能分析。当天然气价格越低,平均电价越高时,CCHP系统投资回收期越短,经济效益越好,相对于传统供能方案节省的运行费用越多。在目前国内常规能源价格条件下,简单循环比回热循环微燃机CCHP系统投资回收期更短,经济效益更优。简单循环微燃机CCHP系统年平均余热利用率、年平均能源综合利用率和节能率都高于国标要求值,系统节能性较好。回热循环微燃机CCHP系统除年平均余热利用率高于国标要求值外,年平均能源综合利用率和节能率略低于国标要求值,系统节能性一般。Taking a complete set of CCHP system powered by micro-gas-turbine as the research object,the performance matching,economic calculation and energy saving analysis of simple cycle and regenerative cycle micro gas turbines were carried out respectively.When the price of natural gas is lower and the average electricity price is higher,the payback period of CCHP system is shorter and the economic benefit is better,and the operation cost is saved more compared with the traditional energy supply scheme.Under the current condition of domestic conventional energy price,the payback period of CCHP system with simple cycle micro gas turbine is shorter than that of regenerative cycle micro gas turbine,and the economic benefit is better.The annual average residual heat utilization rate,annual average comprehensive energy utilization rate and energy saving rate of CCHP system with simple cycle micro gas turbine are higher than the national standard requirements,and the system has good energy saving performance.In addition to the annual average residual heat utilization rate higher than the national standard requirement,the annual average comprehensive energy utilization rate and energy saving rate of CCHP system with regenerative cycle micro gas turbine are slightly lower than the national standard requirements,and the energy saving performance of the system is general.
