Analysis of Electric Fault in a MV DC MgB 2 Transmission Line Cooled by Liquid Hydrogen
Abstract
A submarine superconducting cable for the hybrid transmission of electricity and liquid hydrogen from a wind and solar offshore plant is under investigation in the frame of a project funded by the Italian Ministry of University and Research. The DC MgB2 line is designed to connect the 300 MW offshore plant to the Ravenna port (Italy), approximately 22 km away, at an operating voltage of 30 kV. In this work, an electric model based on a lumped-parameter circuit of a DC medium voltage (MV) line including a MgB2 conductor is coupled with a fluid-dynamic model suited to simulate fast thermodynamic transients in liquid hydrogen.
