摘要
利用CDGES软件建立了高压交流电缆对海底管道交流干扰计算模型,通过模拟计算考察了交流电缆与管道并行间距、并行长度、电缆电压等级等因素对管道交流干扰参数的影响规律,通过分析计算数据得到了海缆与管道在不同电压等级和并行长度下可避免交流腐蚀发生的安全距离,可为海底管道交流干扰的评估以及海管与电缆的路由选择提供一定参考.
Abstract
Software CDEGS was used to build an AC interference model for submarine pipeline interfered by high-voltage AC cables and numerical simulations were conducted to study the effects of parallel spacing,parallel length and voltage grade on the interference parameters of pipelines.Based on the calculation results,the safe distances between cables and pipelines under different voltage grade and parallel length conditions were determined,which could provide reference for AC interference evaluation and routing selection of submarine pipeline.
