Analysis of Electromagnetic Field Compatibility (EMC) Compliance of HVDC Converter Station

Power stations have a very complex electromagnetic environment. The situation is typically worse in an HVDC converter station, because the electromagnetic field (EMF) levels are more severe in proximity to HVDC equipment. Therefore, it is very important to address electromagnetic compatibility (EMC) issues and compliance in the design and operation of HVDC converter stations. This article analyses and discusses in detail HVDC convertor station EMC concerns by focusing on three aspects of the overall design process: analysis method, computer model simulation and EMF calculation. The main purpose of this work is to evaluate the impact of the HVDC station electromagnetic environment on personnel safety and specific equipment by examining the electromagnetic field of the entire converter station under various operating conditions. The analysis methods and procedures introduced in this article can provide guidance and reference for similar EMC analysis and design of offshore and onshore AC/DC converter stations.
