Life and reliability modelling and simulation in COMSOL Multiphysics and MATLAB environments applied to HVDC cable system projects
Deadline: 04/05/2026
Scientific-Disciplinary Group
09/IIND-08 - Electrical Energy Engineering
Description
The activities of the researcher shall include: 1) the development in COMSOL Multiphysics environment of a simulation tool for the distribution of temperature and electric field in HVDC cable system joints under transients of load current and voltage; 2) the refinement of an existing comprehensive algorithm developed in Matlab environment for life and reliability modelling of HVDC cables under typical service stresses (load current cycles, temporary overvoltages, voltage surges, damped oscillating transient voltages), using both a macroscopic approach to electrical conductivity (based on analytical relationships fitted to conductivity measurement results) and a microscopic approach, based on a bipolar charge transport model. 3) Measurements of space charge and electrical conductivity on flat specimens of insulating materials for HVDC cable systems as an experimental support to the activities listed at previous points 1) and 2)
