ANALYSIS OF THE INFLUENCE OF DIFFERENT INSTALLATION CONDITIONS ON AMPACITY OF HVDC SUBMARINE POWER CABLES BY USING CYMCAP SOFTWARE

Abstract

The high voltage direct current (HVDC) using submarine power cables is the optimal solution that carries out the offshore wind source into onshore power systems because of its advantages such as greater stability and less power loss than the high voltage alternating current (HVAC). Currently, there are no guide standards for calculating the ampacity of HVDC submarine power cables according to installation conditions subsea regard to topography, geology, temperature difference …etc in the world, the factors that affect to continued rating current of HVDC submarine power cables. The paper analyses the influence of installation conditions on the ampacity of HVDC submarine cables by using CYMCAP software. The simulation results indicate the influence of installation conditions on the ampacity of HVDC submarine cables in different scenarios and applications for HVDC submarine projects in the future.
