摘要

对于海上变电站的结构设计,在满足其安全性的同时,也要注重提高构件的材料利用率。针对如东海域的某海上变电站,采用SACS软件建立其整体有限元模型,结合Matlab自编程序,开展变电站结构各关键部位承载能力的控制工况研究,在此基础上对整体结构进行多工况下的集成优化,同时以变电站所有构件和导管架主节点为对象,提出海上变电站结构全工况综合定量评价指标——综合UC值（unity check ratio）。与传统方法相比,优化后变电站结构所有构件和导管架主节点强度的综合UC平均值均明显增大,表明构件的材料利用率显著提高。

Abstract

Both the security and material utilization improvement of members should be paid attention to in the structural design of offshore substations. For an offshore substation located in Rudong sea area, a complete finite element model is built in SACS and a Matlab program is also used to investigate the bearing capacity control load case of key positions of the substation. In addition, the whole structure is optimized under multiple load cases. Considering all members and main jacket joints, a comprehensive quantitative index——comprehensive UC（unity check ratio）, is proposed for the offshore substation under all load cases. Compared with conventional methods, the comprehensive UC of all members and main jacket joints is increased significantly after optimization, indicating that the material utilization is improved obviously.
