Seismic Performance Analysis of Offshore Flexible DC Converter Station
摘要
Abstract
Offshore Converter Station Platform is the most critical offshore engineering structure in flexible DC transmission projects for offshore wind power.This study investigates the seismic performance of a specific offshore converter station platform using general-purpose finite element analysis software SAP2000 through time-history analysis.The research results indicate:when the site's seismic fortification intensity is 8 degrees,the seismic performance level of the jacket structure is classified as Level 4,while the converter station platform structure achieves Level 2.The maximum dynamic response amplification coefficient of the platform floors reaches 1.75.For seismic verification of electrical equipment,it is recommended to use either the floor spectrum or floor wave corresponding to the equipment's location for re-evaluation.关键词
