摘　　要：分别采用燃气内燃机和燃气轮机发电机组为主机,结合逐时负荷特性,提出2套分布式供能系统方案,并对供能系统在能源利用率、节能减排和经济性方面进行分析比较。研究表明,天然气价格对各供能系统收益率的影响最大,其次为电价、资产投资,而售冷价格和售热价格的影响相对较小。燃气内燃机供能系统在区域型用户负荷热电比小的应用场合比燃气轮机供能系统更具优势,且与燃气轮机供能系统相比,燃气内燃机供能系统具有较高的项目抗风险能力,对分布式供能系统技术选择和方案配置具有一定的参考价值。Two sets of distributed energy supply systems are presented by using the gas engine and gas turbine units as the main generators, and combining with the hourly load characteristics, and their respective energy efficiency, ener- gy saving and emission reduction and economy are compared. Research shows that the price of natural gas yields the greatest impact on both the energy systems, followed by electricity price and asset investment, but cold and hot selling price produces minor influence. Gas engine energy supply system has more advantages in regions with lower user load heat/power ratio, and has higher project anti-risk capability. The research results can provide reference to the techni- cal selection and scheme configuration of distributed energy supply system.
