Vibration model simplification of converter valve in offshore HVDC substation based on response surface method
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.
