世界各国海底电缆输电工程发展概述

摘要

介绍国内外电网互联海底电缆输电工程的现状,对各区域跨海联网工程发展趋势,以及典型工程的海底电缆保护方式进行了归纳总结。基于海底电缆工程采用输电电压方式,提出了直流输电用于海缆工程的优点与固有缺陷,以及VSC HVDC应用于海缆工程的优势。%The article introduces the present situation of the power grid connection of submarine cable projects home and abroad. It summarizes the development trends of cross ocean power grid connection projects in difference regions and sums up the protection method of typical submarine cable projects. Based on the way of power transmission of submarine cable project, it points out the advantages and shortcomings of the direct current applied in submarine cable projects, and the strong point that VSC HVDC used in the submarine cable projects.
