摘　　要：中国电力与油气输送网络发展迅速,为了研究超高压直流输电线路对埋地油气管道的电磁影响,针对金中直流工程与中缅油气管道进行建模仿真。基于工程设备参数与走廊规划,利用CDEGS软件建立了直流输电线路与埋地油气管道平行和交叉的仿真模型。针对直流线路正常运行、单极接地故障、雷击杆塔3种工况,仿真研究了平行和交叉段管道金属电压及管道防腐层电压分布。结果表明,所选超高压直流线路在各工况下对油气管道的电磁影响均符合限值要求。该研究结果对超高压直流输电工程和埋地油气管道共走廊时的安全运行具有重要实际意义,并可为相关工程设计提供一定参考。To reveal the electromagnetic influence from UHVDC transmission line on buried oil/gas pipeline, mod- eling and simulations are conducted for the China-Myanmar oil/gas pipeline and the Yunnan-Guangxi HVDC trans- mission line. According to the engineering parameters and common corridor design, computational models of the transmission line and pipeline in respective cross arrangement and parallel arrangement are established using the software CDEGS. Then the voltage distributions on the pipeline and its coating induced by the transmission line are calculated for the two arrangements in the conditions of normal operation, single-pole grounding fault, and lightning strike accident of the transmission line. The results show that the electromagnetic influences on the oil/gas pipeline are all smaller than the limited values. This research may be helpful for safe operation of UHVDC transmis- sion line and oil/gas pipeline in common corridor, and may provide a reference for design of relative engineering.
