高海拔地区光伏场高低压交直流电缆选型的研究

Study on selection of high and low voltage AC/DC cables in high altitude area

高海拔地区光伏场地形较为复杂,其集电线路的造价比重相对也较大,而且光伏上网电价较高,其电能损耗也较大,因此电缆截面的选择较为重要。本文通过经济电流密度及压降计算得出最优的电缆截面,为光伏电站电缆设计提供了参考。

Through the calculation of economic current density and pressure drop, the optimal cable cross section is obtained, which provides reference for the design of photovoltaic power station cable.
