Radio frequency performance analysis of high voltage DC converter stations

High voltage DC converter station operation generates radio frequency electromagnetic noise which could interfere with adjacent communication, computer, and carrier system operations. This paper discusses the parametric studies of RF noise characteristics of a typical HVDC converter station. The studies were performed by using a generic computer program for calculating the RF noise from a converter station. The program was developed as part of a series of studies sponsored by the Electric Power Research Institute (EPRI, USA). The calculations provide insight into the EM performance of converter stations and show the effects of individual components within the station.
