摘　　要：海上风电用气体绝缘金属封闭开关设备(GIS)通常安装于海上升压站中,GIS在吊装、运输及正常运行时会受到风浪、潮汐等振动载荷的长期影响。为保证GIS能够满足海上振动工况,在GIS设计阶段需要对其结构强度进行相应的抗振计算或仿真校核。目前,国内关于海上风电用GIS抗振计算的相关规范较少,本文结合多个海上升压站GIS设计经验,对海上风电用GIS安装、运输及运行时的受力特点进行研究,并结合相关标准设计一种用于海上风电GIS抗振仿真的计算方法,为相关设计人员提供参考。Gas insulated enclosed metal switchgear(GIS)for offshore wind power is usually installed in offshore booster stations.GIS is subject to long-term impact of vibration loads such as wind waves and tide during hoisting,transportation and normal operation.In order to ensure that GIS can meet the offshore vibration conditions,it is necessary to carry out the corresponding anti-vibration calculation or simulation check on the structural strength of GIS in the design stage.At present,there are few relevant specifications on anti-vibration calculation of GIS for offshore wind power in China.Combined with the GIS design experience of several offshore booster stations,this paper studies the stress characteristics of GIS for offshore wind power during installation,transportation and operation,and designs a calculation method for anti-vibration simulation of offshore wind power GIS in combination with relevant standards,so as to provide reference for relevant designers.
