摘　　要：针对常规能源供电系统能耗大,以及太阳能供电系统利用率低、供电可靠性差等问题,文章设计了光伏/光热与沼气联合发电系统,并建立该发电系统的仿真模型,以此来研究太阳辐射强度、环境温度及进水流量对该发电系统性能的影响。研究结果表明:当进水流量在一定范围内时,CPC-PV/T系统的热效率随着进水流量的增加呈先急剧升高而后又逐渐降低的变化趋势,并随着太阳辐射强度的降低而降低,当进水流量为0.012 kg/s时,CPC-PV/T系统的热效率最高;当环境温度为0℃且进水流量较大时,CPC-PV/T系统的热效率为0;光伏/光热与沼气联合发电系统综合发电效率的最大值为21.79%,约为单一CPC-PV/T系统的2倍。In order to solve the problems of large energy consumption of conventional energy sources,low utilization efficiency of solar power supply and low reliability of power supply,the photovoltaic/thermal with biogas unit power generation system is designed.At the same time,the corresponding simulation model is established to analyze the performance of the system,on which the influence of the system performance coused by the irradiance,environmental temperature and the water mass flow rate is based.We drew the following conclusions：Within a range of water flow rate,the thermal efficiency of the CPC-PV/T electric heating device increases sharply and then decreases gradually,and decreases with the decrease of irradiance under the condition of a certain influent flow rate.When inlet water flow rate is 0.012 kg/s,the thermal efficiency is the highest.When the ambient temperature is 0 ℃and the influent flow rate is large,the thermal efficiency of the device is 0.The overall efficiency of the system is about 21.78%,which is about twice as large as the efficiency of the stand-alone photovoltaic/thermal power generation system.
