Abstract: In order to promote the smooth construction of 1 000 kV UHV transmission line, reduce the impact of UHV transmission
line on the surrounding environment and reduce public environmental complaints, the model prediction of the typical 1 000 kV
UHV transmission line with the same tower and double circuit was carried out to analyze the electromagnetic environment
influence. The results show that: when the minimum distance between the conductor and the ground as required by the design
specification passes through non-residential areas, the power frequency electric field strength at a height of 1.5 m above the
ground below the line can meet the relevant requirements of GB 8702-2014 Controlling limits for electromagnetic environment;
when the line passes through residential areas, the minimum distance between the wire and the ground should be raised to 36 m,
and the power frequency electric field strength and power frequency magnetic induction strength at a height of 1.5 m above the
ground below the line can meet the requirements of public exposure control limits in GB 8702 -2014 Controlling limits for
electromagnetic environment. In addition, it is suggested that UHV transmission line should be far away from residential areas as
far as possible during site selection stage; In the design and construction stage, the distance between conductor and ground should
be increased to reduce the influence of UHV transmission line on the surrounding environment.
