针对以天然气为燃料、以合同能源管理为运营模式的高温磷酸燃料电池三联供系统经济性问题,基于瞬时系统模拟程序(Trnsys)对南方某三甲医院进行容量优化配置和经济性分析。研究表明,在充分挖掘冷、热、电需求后,年发电小时数达6 000,系统自耗电率约为5%,净发电效率为40.9%,能源综合利用率达75%,目前进口设备价格约1.2 万元/kW,系统总投资约为6 900万元,项目投资回收期为18.73年,需大力补贴才能实现示范落地。系统日常处于较高负荷率,如遇停电,系统能够在不间断电源提供的过渡时间内迅速爬升负荷,作为重要负荷的保障电源,为医院节省柴油发电机房投资约250万元。结合其他类型燃料电池国产化进程,若磷酸燃料电池造价降至0.6 万元/kW,项目全投资收益率将达5%以上,在低息贷款条件下,此类项目将成为经济性良好的清洁、高效分布式供能新形式。
To address the economic issues of a high-temperature phosphoric acid fuel cell trigeneration system taking natural gas as fuel and taking an energy management contract as operation model, capacity optimization configuration and economic analysis were conducted for a tertiary hospital in southern China based on an instantaneous system simulation program (Trnsys). The results showed that after fully tapping into the demands for cooling, heating, and electricity, the system achieved 6 000 h of power generation per year, with a self-consumption rate of about 5%, a net power generation efficiency of 40.9%, and an overall energy utilization rate of 75%. Currently, the price of imported equipment is around 12 000 yuan/kW, with a total system investment of about 69 million yuan. The project's investment payback period is 18.73 years, and substantial subsidies are required for successful demonstration and implementation. The system typically operates at a high load factor. In the event of a power outage, it can rapidly ramp up the load within the transition time provided by the uninterruptible power supply, serving as a crucial backup power source. This helps the hospital save about 2.5 million yuan in investment for diesel generator rooms. Considering the localization process of other types of fuel cells in China, if the cost of phosphoric acid fuel cell drops to 6 000 yuan/kW, the project's rate of return on investment will exceed 5%. Under the conditions of low-rate loans, such projects will become a cost-effective, clean, and efficient new form of distributed energy supply.
