光伏电站电缆布局优化设计

Optimal Design of Cable Routing for Photovoltaic Plants

在能源需求和环境污染的双重压力下,太阳能光伏发电受到了大力支持,光伏产业得以迅速发展。建设经济高效的光伏电站一直都是光伏产业发展的重要目标,因此,研究如何优化光伏电站设计并降低光伏项目造价具有重要的意义。本文从光伏电站电缆排布对光伏电站造价的影响出发,利用改进的广度优先搜索邻居(broadfirstsearchneighbors,BFSN)合理排布直流汇流箱和逆变器的位置,对光伏阵列的电缆路径进行了优化。通过和人工布线方案比较,表明该方法可以快速获得合理的电缆排布及汇流箱和逆变器安装位置,有效减少光伏电缆使用量,降低了光伏电站造价成本,减少设计人员的工作量,为光伏电站设计提供合理和有效的解决方案。

Under the dual pressure of energy demand and environmental pollution,photovoltaic generation is strongly supported.And the photovoltaic industry is rapidly developed.Constructing economic and efficient photovoltaic power station is always one of the important goals of the development of the photovoltaic industry.Therefore research on how to optimize the design of photovoltaic power station and decrease the cost of photovoltaic project is of great importance.The paper set about from the effect of cable arrangement on the cost of photovoltaic power station construction,using improved broad first search neighbor algorithm to arrange reasonably combiner box and inverter for the optimization of cable path of photovoltaic arrays.Compare to the manual wiring,the method proposed in the paper can quickly get reasonable cable layout and the installation location of combiner box and inverter,thus effectively decreases the cost of photovoltaic power station construction and lessening the workload of the designer,provides rational and effective solutions for photovoltaic system design.
