大型渔光互补光伏电站场区总体布置优化研究

Research on the Optimal Overall Layout of Large-Scale Fishing-SolarComplementary Photovoltaic Power Station

对于大型渔光互补光伏电站项目,场区的总体布置方案对项目的经济性起着决定性的作用。针对以往主观定性分析的不足,提出了一种定量分析确定大型渔光互补光伏电站场区最优布置的方法。该方法基于标准化方阵的设计思路,合理确定组件、箱变、逆变器(汇流箱)布置及电缆桥架路径和运维检修通道,使高低压交直流电缆和配套电缆桥架等材料和建安总造价最低。结合当涂光伏项目实际案例证明,该方法显著提高了项目的经济效益。

The overall layout of the site plays a decisive role in the economy of the large-scale fishing-solar complementary photovoltaic power station.To improve the shortcomings of previous subjective qualitative analysis,this paper puts forward a quantitative analysis method to determine the optimal layout of large-scale fishing-solar complementary photovoltaic power stations.Based on the standardized square matrix,this method determines the layout of components,box-type substations,inverters(combiner boxes),the paths of cable bridge and the operation and maintenance channels to make the overall cost of high and low voltage AC and DC cables,cable bridges,and construction and installation work minimized.This method can increase the economic benefits significantly with the proof of Dangtu photovoltaic project.
