摘要
由于光伏电站的特点和经济技术发展对经济电流密度计算参数的影响,现有的手册、标准和规范上的经济电路密度曲线已不能满足光伏电站经济电流截面的选择。考虑相关因素的影响,通过实例对大型光伏电站的集电线路进行经济电流密度计算,进而根据集电线路的载流量选择其经济截面,对该截面进行压降检验,均满足了规范要求。
Since features of photovoltaic station and economic technology development have impacts on economic current density cal- culation parameters, the existing economic current density curves of hand-books, standards and regulations could not meet the selection of photovoltaic station economic current section. In consideration of impacts of related factors, this paper carried out economic current density calculation for large-scale photovoltaic station＇s power collecting lines via actual case, then according to carrier flow, its economic section was selected, voltage reduction test was carried out, to meet regulation requirements.
