Modelling and simulation activities play a central role in the analysis and development of high-voltage direct-current (HVDC) systems, which are used to transmit large amounts of power over long distances. For this purpose, reliable numerical tools that can deal with complex geometries and various (usually non-linear) materials are needed. The NEWGEN article ‘’FEVER – Fem Electrothermal solVER: application to an HVDC joint’’ discusses the simulation of temperature and electric field distributions in an HVDC cable-joint configuration. The authors of this work are researchers at the University of Bologna, Department of Electrical, Electronic and Information Engineering (DEI) which is one of the NEWGEN consortium partners. They have developed a finite element open-source MATLAB code called FEVER – Fem Electrothermal solVER to solve thermal, electric and magnetic stationary problems on plain or axially-symmetric domains discretized using triangular meshes. In this work, a 540 kV HVDC joint-cable system was considered and the results obtained with FEVER were validated through comparisons with both analytical formulas and simulations from COMSOL Multiphysics. The results are also discussed in terms of thermal and electrical stress for the system, which are crucial factors in the reliability and efficiency of HVDC transmission apparatuses. This paper was published in the 2023 IEEE International Conference on Environment and Electrical Engineering and 2023 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe).
