This morning, SuperGrid Institute presented at the second conference on Power Transmission in Africa (Johannesburg) its vision on new transmission technologies and architecture, shaping the future grids. With emphasis on the fantastic opportunity that the latest HVDC technologies and solutions represent for a robust and interconnected power system in Africa, able to address major issues linked to energy transition.

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”

By |January 16th, 2020|Categories: Phd, Power Electronics & Converters|

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.
