摘要
电力电缆在光伏电站中起着电力传输的重要作用，本文首先分析了电缆在水上漂浮光伏电站运行特点，通过对比铜芯电缆与铝合金电缆在性能上的差异，在电缆选型中推荐采用弯曲半径较小、抗疲劳性能更优的铝合金电缆。同时综合考虑电缆敷设安全可靠以及造价因素，本文介绍一种新型电缆桥架结构形式，以抵消水面波动引起的桥架横向及纵向的形变。
Abstract
power cable plays an important role in the transmission of power in photovoltaic power station. Firstly，this paper analyzes theoperating characteristics of the cable in floating photovoltaic power station on water，and compares the performance difference between copper corecable and aluminum alloy cable. Aluminum alloy cable with small bending radius and better fatigue resistance is recommended for cable selection. Atthe same time，considering the safety and reliability of cable laying and the cost factors，this paper introduces a new type of cable bridge structureto counteract the lateral and longitudinal deformation caused by water surface fluctuation.
