Versatile and transparent model to estimate the disturbance potential of overhead transmission lines in the context of HVDC transmission using voltage source converter

Estimating the disturbance potential of an overhead transmission line (OHL) on radio services in the context of HVDC transmission using voltage source converter (VSC) is a crucial part in the process of electromagnetic compatibility compliance evaluation. Although the multilevel VSC technology is regarded as the solution for future direct current (DC) grids, a model to estimate the disturbance potential of such a system is still missing in international standards. This paper presents a versatile and transparent approach to quantify the disturbance potential by describing the relevant parameters as statistical quantities derived from available information on the basis of CISPR 16-4-4. In the end, the presented procedure is applied on an exemplary use case.
