【摘要】：以光伏组件的传热机理分析为基础,从传热学的角度建立了一种光伏组件的一维热模型。该模型同时考虑了光照辐射、环境温度与风速等气象因素,可实现对太阳能电池温度的在线预测,其有效性得到了实验结果验证。针对传统的光伏组件输出特性评估中仅考虑光照度与环境温度、不计及风速影响的缺陷,提出了基于热模型的精确在线评估方法。该方法为光伏电站的建站选址、改造设计提供理论依据,同时有助于光伏组件的运行状态监测与故障诊断。
[Abstract]:Based on the analysis of heat transfer mechanism of photovoltaic module, a one-dimensional heat model of photovoltaic module is established from the point of view of heat transfer. The model also takes into account meteorological factors such as light radiation, ambient temperature and wind speed. The on-line prediction of solar cell temperature can be realized, and its validity is verified by experimental results. Aiming at the defects of traditional photovoltaic module's output characteristic evaluation, only light intensity and ambient temperature are considered, and the influence of wind speed is not taken into account. An accurate on-line evaluation method based on thermal model is proposed, which provides theoretical basis for site selection and retrofit design of photovoltaic power station, and is helpful for monitoring and fault diagnosis of photovoltaic modules.
