Influence Research on Induced Voltage and Current of Multi AC Transmission Lines to the Power Line Under Construction in the Same Corridor

  • Multi power transmission lines arranged in the same corridor can avoid the land division, and reduce the adverse effect on the local planning and development, but the personal safety of operators in the process of towers and conductors erection of subsequent power lines should be seriously considered as a result of the induced voltage and current of the energized transmission lines in the corridor. One DC line under construction taken as an example, induced voltage and current generated from multi AC transmission lines in the same corridor were calculated and studied with ATP-EMTP electromagnetic transient program. The influence factors including the operating mode of the system, the distance between power lines and length of stringing conductors were analyzed at the same time. The research shows that the induced voltage and current are not significant because of lines under construction far from energized lines in the same corridor, while the induced voltage along the stringing conductors will be paid much attention to when the length of stringing conductors are much longer. The research results also have guiding significance to power lines′ construction which is adjacent to live lines.
