A novel grounding mode for enhancing current rating of AC submarine cables

What is it about?

This paper proposes a novel grounding mode to suppress the circulating currents and to enhance the permissible current rating of general submarine cables. To achieve the best performance, the optimal grounding impedances of the novel grounding mode for general submarine cables are given. Theoretical analyses and numerical results validate the good performances of the novel grounding mode in reducing the power loss and short-circuit overvoltage.
