摘要随着城市电力的扩张以及电力需求的增大,为解决地下电缆传输空间用地紧张的问题,新建的直流电缆将敷设在原有的交流隧道中,从而使电缆隧道内电磁场变得更为复杂。该文针对±320kV直流电缆和220kV交流电缆共沟敷设隧道建立电磁场仿真模型;计算隧道内的电磁场分布以及交流电缆在直流电缆上产生的感应电压;分析交直流电缆之间的距离、交流电缆和直流电缆的敷设方式以及单相交流电缆故障对电缆隧道电磁环境的影响,最后根据计算结果提出交直电缆间的最小距离以及交直流电缆的最优敷设方式。

Abstract：With the expansion of urban power and the increase of the power demand, the alternative current (AC) and direct current (DC) cables will be laid in the same tunnel to solve the shortage of underground cable transmission space, which makes the electromagnetic field of the cable tunnel more complicated. In this paper, the electromagnetic field simulation model was established for ±320kV DC cables and 220kV AC cables co-laying tunnel. Then the electromagnetic field distribution in the tunnel and the induced voltage generated by AC cables on DC cables were calculated. The influence factors of electromagnetic environment in the cable tunnel were analyzed, such as the distance between AC and DC cables, the laying methods of AC cables and DC cables, and single-phase AC cable faults. Finally, the minimum distance between the AC and DC cables and the optimal laying method of the AC and DC cables were proposed.

Key words： AC and DC cable electromagnetic field laying method
