摘要
根据光伏/光热(PV/T)系统的能量平衡和能量转换原理,建立了PV/T系统的热电模型,针对PV/T系统的热电效率、电池板温度间的耦合问题,通过MATLAB迭代求解法,解决了PV/T系统中热电参数耦合求解问题,得到了PV/T系统的效率曲线,分析计算了系统组件长度和工质流速等参数对性能曲线的影响;同时,针对PV/T系统与普通光伏组件进行了实验研究,试验测试了两系统的电压、电流、功率、板背温度等特性参数,并与仿真结果进行了对比。
Based on the energy balance and conversion principle,a thermal and electrical model for the solar photovoltaic/thermal (PV/T) system is developed to solve coupled thermal and electrical parameters by using the iteration method of MATLAB.The variation of thermal and electrical efficiency is given and the influence of the PV/T system assembly length and working medium velocity change on the performance curve of the PV/T system is analyzed.Experimental study is conducted to compare the simulated results with the experiment data of general photovoltaic assembly including voltage,current,power and temperature of the back panel.
