PhD Rayane Mourouvin: “Converter control in a power system with high penetration of renewable energy”
This work focuses on the transmission grid level and investigates the control of VSCs interfacing renewable sources in hybrid power systems where PE and SG coexist.
PhD Paul Verrax: Transient-based fault identifcation algorithm for the protection of meshed HVDC grids
The present thesis investigates the concept of a single-ended fault identification algorithm based on the estimation of the fault parameters.
PhD Pascal TORWELLE: “Development of a HVDC grid protection strategy based on hybrid OHL and cable lines”
This thesis identify the major challenges when considering the application of non-selective fault clearing strategy to hybrid grid structures and to propose solutions.
PhD Piotr DWORAKOWSKI “Modelling and analysis of medium frequency transformers for power converters”
The modelling and analysis are essential in the development of the MFT technology which is attracting lots of research and industrial interest.
PhD Hadiseh Geramirad “EMC study of a 1.7 kV SiC MOSFET gate driver”
The proposed gate driver achieves a better trade-off between losses & conducted emissions compared to the classical series-connected passive resistors for SiC MOSFET gate drivers.
Phd Paolo ERRANTE “Liquid Spray Injection inside the expansion volume of a CO2 High Voltage Circuit Breaker”
In the framework of the research activities of the High Voltage Substation Equipment program of SuperGrid, it has been proposed to introduce such species by means of an evaporative liquid spray. The interaction between injected droplets and the mixture of hot gases successively flowing into the chamber and vented outside the chamber during the mechanical separation of the electric contacts should allow spray evaporation and transport of the modified gas mixture towards the arc region.
Phd Majed Eddine MOUSTAID “Experimental development of a thermosiphon loop for thermal regulation of power electronic devices”
The work of this thesis focuses on the experimental development of a passive and biphasic cooling system to cool down power electronics. Some of those modules are mean voltage power converters developed by Supergrid Institute. Some constraints have been imposed upstream to this project. While some limitations are of the technological nature, other constraints are related mainly to the environmental and biological aspects. The first part of this thesis was to find a suitable cooling system that could be adapted to the project specifications. After some research, we decided to build a loop thermosiphon filled with NOVEC 649.
