城市220kV主变对地铁控制中心电磁干扰分析

Analysis on Electromagnetic Interference of Urban 220kV Main Transformer to Metro Control Center

地铁建设是缓解我国城市交通运输压力的最为有效的手段,近年来得到了飞速发展。为了有效地利用城市地块、统筹城市规划,建设单位或政府部门有时希望将同地段的楼房及其设备、功能需求进行集成及整合,随之而来的高压交流电气设备与地铁控制系统之间的相互影响问题也显现出来。本文结合武汉赵家条地块的轨道交通及规划情况,重点、分析了220kV城市主变电所对地铁控制中心的电磁干扰影响,其研究结论对能否将两者同楼集成建设具有现实指导意义。

Subway construction is the most effective means to relieve the pressure of urban transportation in China and has been developed rapidly in recent years.In order to make effective use of urban land and coordinate planning of the city,construction units or government departments sometimes hope to integrate and incorporate the buildings and their equipment and functional requirements in the same area.The problems of interaction between high-voltage AC electrical equipment and subway control system are also appeared.Combining the rail transit and planning of zhaojiatiao in Wuhan,this paper focuses on the electromagnetic interference impact of 220kV urban main substation on the metro control center.The conclusion of this research has practical significance for the integration of the two buildings.
