Abstract :
This paper analyzes dc cable transient modelling issues for voltage source converter (VSC) based high voltage direct current (HVDC) transmission systems, as proposed for large-scale renewable power integration, for example, offshore wind farms. Detailed dc cable models with different degrees of accuracy are analyzed for utilization in the analysis and simulations of dc fault conditions. This fault study is helpful for the protection system design of large-scale renewable energy power systems to realize a reliable dc transmission system for the future.
