摘　　要：燃气分布式能源系统(CCHP)可实现能源的梯级、循环、高效利用,并有效避免了多次转换、传输损失,接近负荷侧的“直供”特性,具备高的能源利用效率和经济效益。为满足负荷侧与源侧的科学匹配,以S医院为用能研究对象,对其用能负荷数据和气象数据进行为期1年的检测,并对采集的数据进行统计、整理、分析,获取S医院的负荷特征。拟定3种供能方案,按“以热定电”的设计原则,以年综合费率法选取最佳方案。测算表明:项目装机容量为0.6 MW,初始投资671.8万元,财务内部收益率15.98%,投资回收期6.63年;市场、经济、政策、技术及其他风险可控。针对冷热电均有需求,且负荷稳定、能耗规模小的场景,适合采用燃气分布式供能。The Gas Distributed Energy System(CCHP)can realize the cascade,circulation,and efficient use of energy,and effectively avoid multiple conversions and transmission losses.It is close to the“direct supply”characteristics of the load side,and has high energy utilization efficiency and economic benefits.In order to meet the scientific matching between the load side and the source side,the S Hospital was used as the research object,its energy load data and meteorological data were tested for one year,and the collected data were counted,sorted,analyzed,and obtained Load characteristics of S hospital.Three energy supply schemes were drawn up,and the best scheme was selected according to the design principle of“using heat to determine electricity”and the annual comprehensive rate method.Calculations show that:the installed capacity of the project is 0.6 MW,the initial investment is 6.718 million yuan,the financial internal rate of return is 15.98%,and the investment payback period is 6.63 years;the market,economy,policy,technology and other risks are controllable.For this reason,for scenarios where there is a demand for cooling,heating,and electricity,and the load is stable,and the scale of energy consumption is small,it is suitable to use gas distributed energy supply.
