Design and simulation of the photovoltaic/thermal with biogas unit power generation system
摘要
Abstract
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.关键词
