个性化光伏布置在多坡向复杂山地中的应用

Application of customized PV solar system layout in complex mountainous terrain characterized as multi slope faces

根据已建成的某光伏电站实际运行数据与前期可研阶段理论计算结果进行的对比分析,验证所采用的个性化光伏设计对多坡向复杂地形场地的适用性。考虑到资源偏小年景及设备调试、故障,认为光伏电站实际发电量与可研阶段成果相对一致。经过对不同发电单元的发电量差异进行对比分析,认为造成不同发电单元发电量差异的最大原因是东西向顺坡布置光伏组件占比的不同。各发电单元的实际发电量与其光伏组件东西向顺坡布置占比有极强的正相关。

Based on the comparative analysis between the practical operational data and the theoretical calculation results in feasibility study stage of a PV solar station, the applicability of customized PV solar system design in complex terrain with multi slope faces was checked and tested. It was showed that the practical output Was consistent with the feasibility study results considering the fact of solar poorer year and equipment maintenance and failures. By comparing and analyzing the output of different power units, it was found that the output difference was caused by the different proportion of east - west consequent PV arrays. It revealed that there is a strong positive correlation between the practical output of power units and the proportion of east - west consequent PV arrays.
