Analysis on the Electromagnetic Environmental Factors of 500kV Double Circuit Transmission Line

Abstract:

This paper calculates frequency magnetic field strength by the Ampere's law, and analyzes the main factors affecting the electromagnetic environment of the 500kV Double Circuit Transmission Lines. In the same electromagnetic transmission line calculation parameters, optimization of phase sequence can effectively reduce the frequency magnetic field strength; with the increase of the distance, the line frequency magnetic field strength significantly reduces away from the center line within 25m. Finally, the paper obtains the phase sequence arrangement with minimal impact on the electromagnetic environment and the minimum ground clearance meeting the environmental requirements.
