摘要:

摘要:光伏电站前期设计中需要对汇流箱的安装位置进行选择,选址的准确与否关系着能否使方阵内部各个光伏组串直流电缆与汇流箱的距离总和最小,对于光伏系统设计而言,做好汇流箱选址优化非常重要。以电缆使用量最少为优化目标,不仅可以节省光伏电缆用量和成本,而且能减少电缆压降损耗,提高系统效率。结合光伏电站的实际情况与特点,根据曼哈顿距离算法对汇流箱的选址优化问题建立数学模型,得出了目标函数关系式,初步给出了汇流箱的最经济点位置(即直流线缆用量最省)和验证过程,并通过实际案例进行了分析。

Abstract:During photovoltaic power plant design, the position of combiner box is critical. Less cable usage will not only save cost, and will also reduce cable voltage drop loss. Combines with the facts and features of photovoltaic power plant, the mathematic model of combiner box site selection was built bases on Manhattan distance. The objective function was indicated. The most cost efficient point was provided and proved.
