摘要
提出耦合太阳能的固体氧化物燃料电池–微燃机–冷热电联供系统(solid oxide fuel cell-micro gas turbine-combined cooling,heating and power system,SOFC-MGT-CCHP),建立SOFC-MGT-CCHP系统与太阳能热水系统模型,并将二者耦合。以某旅馆用户为例,根据不同季节用能特点提出3种典型运行策略。并根据以电定热、以热定电以及是否耦合太阳能等系统运行方式进行对比研究,研究结果表明:耦合太阳能的SOFC-MGT-CCHP系统按照以热定电方式运行最为节能。在满足用户用能需求情况下,相较于不利用太阳能的以热定电运行方式,系统日均一次能源节约率、一次能源利用率、CO_(2)减排率最高提升2.88%、14.2%、3.76%;相比于不利用太阳能的以电定热运行方式,三者最高分别提升26.31%、83.05%、26.53%。
This paper proposed a solid oxide fuel cell-micro gas turbine-combined cooling,heating and power system(SOFC-MGT-CCHP)coupled with solar energy,the models of both the SOFC-MGT-CCHP system and the solar hot water system are established and coupled together.Then,taking a hotel user as an example,three typical operating strategies were proposed according to the energy consumption characteristics of users in different seasons.And comparative studies were made based on system operation modes such as heating by electricity,electricity by heat,and whether to couple with solar energy,etc.The research results show that the SOFC-MGT-CCHP system coupled with solar energy is the most energy-efficient when it operates at the mode of heating by electricity.In the case of meeting the energy requirements of users,compared to the operation mode of electricity by heat that without integration with the solar energy,the system’s average daily primary energy saving rate,primary energy utilization rate and carbon dioxide reduction rate are increased by 2.88%,14.2%and 3.76%respectively.And compared with the operation mode of heat by electricity that without integration with the solar energy,they are increased by 26.31%,83.05%,and 26.53%respectively.
