水面光伏电站柔性连接电缆敷设方案探讨

Exploration of Flexible Connection Cable Laying Device for Surface Photovoltaic Power Stations

水面光伏电站建设在水面上,需要承受水面波浪荷载及风荷载,产生结构疲劳应力。当电缆疲劳应力或疲劳循环次数超过材料限值时,电缆则会产生疲劳破坏。通过对产生该问题的原因进行分析,并针对此提出了用于水面光伏电站的新型柔性连接电缆敷设装置,并在工程中进行了运用,结果表明柔性连接电缆敷设装置能够有效减少电缆的疲劳破坏,降低其检维修成本。

The surface photovoltaic power station is built on the water surface,which needs to withstand wave and wind loads,resulting in structural fatigue stress.When the cable fatigue stress or fatigue cycle number exceeds the material limit,fatigue failure of the cable will occur.By analyzing the cause of this problem,a new flexible connection cable laying device for water surface photovoltaic power station is proposed and applied in the project.The results show that the flexible connection cable laying device can effectively reduce the fatigue damage of cables and reduce their maintenance costs.
