中文摘要:

      沙漠环境下，测试积沙条件下光伏组件的输出功率与温度和积沙量的数值，通过运用相关系数的方法，进而分析在不同季节时积沙、温差、功率损耗率的相互关系。结果表明秋季时的积沙量高于其他季节，夏季的温差波动最大，冬季的功率损耗要高于其他季节。三者的相关系数在不同季节时相差较大，对组件的作用存在着较大的差异，在秋季时的影响作用要大于其他季节，积沙与温度相关系数为-0.862，温度与功率损耗率相关系数为-0.866，而积沙与功率损耗率相关系数达到了0.852。得出相关规律，对沙漠环境下光伏电站在不同季节的清洁规划提供一定的参考。

英文摘要:

      In the desert environment, the output power of photovoltaic modules was tested under the condition of sand accumulation. The relationship between sand accumulation, temperature difference and power loss rate in different seasons was analyzed by using the correlation coefficient method. The results show that the sediment accumulation in autumn is higher than that in other seasons, the temperature difference in summer fluctuates most, and the power loss in winter is higher than that in other seasons. The correlation coefficient of three varies greatly in different seasons, and there are great differences in the role of components. In autumn, the influence is greater than that in other seasons. The correlation coefficient between sediment accumulation and temperature is -0.862, the correlation coefficient between temperature and power loss rate is -0.866, and the correlation coefficient between sediment accumulation and power loss rate is 0.852. The relevant laws are obtained to provide some reference for the clean planning of photovoltaic power plants in different seasons in desert environment.
