漂浮式开关站平台锚固系统分析

An analysis of the anchorage system for floating switch station platform

本文以安徽省濉溪县采煤塌陷区光伏发电项目的漂浮式开关站平台为例,介绍了对漂浮式开关站平台稳定性和系泊系统的分析方法。根据此方法对平台在所在水域中承受的各种环境载荷进行分析,并以此作为条件,用AQWA软件对平台在水中的稳定性和运动响应进行计算分析,根据计算结果找到造成平台晃动最大的极限波浪数据,在这极限工况下,进一步进行系泊响应分析,计算出平台随锚固位置不同,锚绳受力和平台晃动幅度的变化,根据计算结果总结出漂浮式开关站平台锚固效果随着锚固深度的增加逐渐下降,同时随锚绳和水平面夹角的减小逐渐增大等平台锚固系统设计需要注意的问题。

This paper introduces an analysis method of the stability and mooring system of the floating switch station platform based on the photovoltaic power project in the mining subsidence area of Suixi,Anhui Province.Based on this method,it analyzes various environmental loads for this project,it analyzes the stability of floating switch station platform in water with AQWA,it finds the limit environment condition of the wave in this area that causes the floating switch station platform drift.Further it analyzes the mooring system and calculates the anchor force and the drift amplitude with different anchoring positions.According to the calculation results,it is concluded that the anchoring performance of the switch station platform decreases with the increase in the anchoring depth,and it is increase with the decrease in the angle between the anchor line and the horizontal plane.
