摘　　要：本文提出了一种基于代理模型的海上换流站结构与气体绝缘开关设备(GIS)的一体化耦合分析方法,以提高对GIS设备在复杂海洋动力作用下的评估效率及准确性。通过精细化模型及基于响应面法代理模型的建立,在验证了代理模型的动力特性准确性的基础上,建立了结构-设备一体化耦合模型,并深入分析了GIS设备在海上运输、浮托对接、波浪振动和地震作用等关键工况下的基底响应及强度水平。研究结果表明:GIS设备动力响应与结构型式紧密相关,一体化耦合分析是准确求解设备振动的有效手段,且其中的浮托对接和地震工况是服役和在位中的关键工况,为GIS设备的适海性研究和设计优化提供了思路。An integrated coupling analysis method of offshore converter station structure and gas-insulated switchgear(GIS)based on the agent model is proposed to improve the efficiency and accuracy of the assessment of GIS equipment under complex ocean dynamics.Through the refinement model and the establishment of the proxy model based on the response surface method,the integrated structure-equipment coupling model is established on the basis of verifying the accuracy of the dynamic characteristics of the proxy model,and the base response and strength level of the GIS equipment under the key working conditions of marine transportation,floating bracket docking,wave vibration and seismic action are deeply analysed.The results show that the dynamic response of GIS equipment is closely related to the structural type,and the integrated coupling analysis is an effective means to accurately solve the vibration of the equipment,and the pontoon docking and seismic conditions are the key conditions in service and in position for the study of the seaworthiness and design optimisation of GIS equipment.
