摘要
研究复合抛物面聚光器(CPC)型太阳能光伏/光热联合利用(PV/T)系统中太阳能换热系统的机理建模问题,针对电池板的初始温度、光照强度以及下层流道流体流量对电池板温度的影响,分别采用分布参数法和集总参数法,根据能量守恒定律对换热系统进行机理建模,最终得到系统的传递函数。利用Matlab对所得函数进行仿真,得到系统的特性曲线,验证了所建模型的可行性和合理性。
This paper studies the mechanism modeling problem of Solar Heat Exchange Systems which is part of compound parabolic concentrator （CPC） solar photovoltaic-thermal （PV/T） system. According to the law of conservation of energy, the mechanism model which reflects the influence of the solar cells＇ initial temperature, the solar radiation and the mass flow rate of the fluid on the temperature of solar cells is established by using the distributed parameter method and lumped parameters method respectively. The transfer functions of the system and thecurvesimulated by Matlab have been got, the dynamic characteristic of the system is analyzed. The feasibility and ratimality of the proposed model has been verified feasibleand rational.
