3D-MoM analysis of radio frequency noise radiation from HVDC converter station

Radiation of radio frequency noise from power transmission lines has been analyzed using a three dimensional method of moments (MoM) considering towers and buildings at a DC-to-AC converter station. The towers and the buildings reflect the electromagnetic waves. A 1/400-scale reduction model of the station has been fabricated for measurements to confirm the MoM analysis. Both results were confirmed by the measurements on site, and have a good agreement in the electromagnetic field distribution.
