不同敷设环境下高压直流海缆的温度场分析
Analysis on Temperature Field of High Voltage DC Submarine Cable in Different Laying Environment
摘要
Abstract
Professional finite element software COMSOL Multiphysics is used to establish temperature field models for land section,tidal flats section and seabed section of single-core DC submarine cable,as well as carry out simulation calculation on conductor temperature of the submarine cable.It is verified validity of applying finite element algorithm in engineering practice by comparing simulation result of finite element algorithm and that of IEC 60287 analytical method,and concluded that bottleneck section of carrying capacity of the DC submarine cable with buried laying mode is land section.Finite ele-ment method is used for analyzing influence on temperature field distribution of buried submarine cable by factors such as buried depth and bipolar spacing of the cable,ground air temperature,convective heat transfer coefficient,and so on.关键词
