Research on the electromagnetic environment of 110kV six-circuit transmission line on the same tower

In order to provide guidance for construction and operation of 110kV six-circuit transmission line on the same tower, the electromagnetic environment of transmission line is researched intensively. Firstly, the model of 110kV six-circuit transmission line on the same tower is established in MATLAB. Secondly, the power frequency electric field intensity, the power frequency magnetic field density and radio interference value under different phase sequence arrangements are calculated. Finally, the impacts of different phase sequence arrangements on electromagnetic environment around transmission line are analyzed. The results show that the empirical phase sequence arrangement is the better optimized layout, and the most optimized one theoretically is found out by travelling all phase sequence arrangements.
