【摘要】 为解决可再生能源存在的利用率低等问题,本文结合太阳能热利用技术、太阳能光伏技术、燃料电池系统、地源热泵系统等一系列技术,设计了一套多源热电联产系统。通过计算建筑负荷,在Trnsys仿真平台中建立仿真模型,对系统各部件进出口温度等进行相关分析。同时,为了对比分析系统的性能,在Simulation Studio中,通过连接各个功能不同的模块,建立了单一PV/T系统仿真模型。仿真结果表明,单一PV/T系统的全年平均光电效率为0.082 5,全年发电量约为1 745kW·h;带有冷却循环多源系统中的PV/T集热器,其全年平均光电效率为0.123 8,比单一系统提高了50.06%,发电量为2 560kW·h,提高了815kW·h。说明带有冷却循环的多源系统,比单一PV/T系统在发电量及光电效率等方面均有显著提升。该研究可提高再生能源的利用率。更多还原
