多因素耦合对光伏组件表面温度影响的试验研究
|
摘要
低温条件(0℃以下)对光伏发电量影响的相关研究较少,为进一步研究温度对发电量的影响,该文首先研究各个因素对光伏组件表面温度的影响。运用灰色关联分析定量分析影响光伏组件表面温度的多种因素,分析得到各影响因子与光伏组件表面温度的最佳关联顺序为太阳辐照度>环境温度>风速>湿度。并采用多元线性回归方程分析各影响因素与光伏组件表面温度之间的关系,结果为太阳辐照度每升高1 W/m~2,光伏组件正面温度增加0.037℃;环境温度每升高1℃,光伏组件正面温度增加0.851℃;风速每升高1 m/s,光伏组件正面温度降低0.421℃;湿度每升高1%,光伏组件正面温度增加0.248℃。其次,根据太阳电池转换特性还研究了光伏组件表面温度对光伏组件输出电压、电流及发电量的影响,并采用一元线性回归方程分析其关系,结果为光伏组件正面温度每升高1℃,发电量增加0.016 Wh。
The research on the effect of low temperature(below 0 ℃)on photovoltaic power generation is relatively fewer. In order to further study the influence of temperature on power generation. The effect of each factor on the surface temperature of PV module is studied in this paper. The factors were analyzed quantitatively by using the grey relational analysis. The optimal relevance order is solar irradiance,the ambient temperature,wind speed and humidity. Further,the relationship between the factors and the surface temperature of PV module were analyzed by using multiple linear regression analysis. The results showed that the PV module positive temperature increase 0.037 ℃,when the solar irradiance increases 1 W/m~2,increase 0.851 ℃ when the ambient temperature rise 1 ℃,decrease 0.421 ℃ when wind speed increases 1 m/s,increase 0.248 ℃ when the humidity increase 1%. Secondly,according to the characteristics of photovoltaic cells conversion,the effect of the surface temperature of PV module on output voltage,current and power generation was also studied experimentally. And the relationship was analyzed by using the linear regression equation.The result showed that the power generation increased by 0.016 Wh when PV module positive temperature increase 1 ℃.
