摘要
对于有均衡或非均衡负载的独立光伏系统,在计算最佳倾角b时,可先计算出不同倾角下各月倾斜面上的辐射量占该倾角下全年总辐射量的比例以及各月负载耗电量占全年总耗电量的比例。将以上两种比例进行比较,取使得各月辐射比例与负载比例最匹配的倾角为最佳倾角。匹配程度可用最小二乘法计算。文章辐射数据使用上海市1961-1980年的太阳光辐射月平均数据,对均衡及非均衡负载计算了最佳倾角,并做了分析。
In order to calculate the optimum angle of solar battery system for both even and uneven load , this paper calculated the radiation on the incline in each month and divided the value of each by it of the whole year to get the ratio. Then got the load ratio in the same way. After that compared the two ratios to judge whether the angle is suitable for the load by using least difference square .This paper selected the city of shanghai to exam the above theory, the data of radiation of shanghai are the monthly average direct and diffuse radiation. In the example , calculated both the even and uneven load and analysed them.
