SULPHUR hexafluoride, SF6, is the most common compressed gas used in high voltage power equipment since the 1950s and in HV transmissions and substations applications (GIS, GCB, GIL …), SF6 holds a prominent place because of its dielectric and chemical performance (high dielectric strength, non-toxicity, low condensation temperature, thermal stability, non-flammability, chemical inactivity with the other constituent materials of the apparatus, availability and moderate cost). It is one of the best insulators gas known today.

TM1 test rig renovation

Why do we stil need experimental test-rigs in hydraulic sciences? We use extensively computatinal sciences to estiate performances of runners. Although it is accurate, Computatinal Fluid Dynamics (CFD) need to be checked with experimental data especially for cavitatin and transients. For that reason when prototype machines are greater than 5 MW or larger than 3 m of diameter it is mandatory to estiate on reduced scaled model with a great accuracy performances according to IEC 60193.

SuperGrid Institute Part of H2020 European Project PROMOTioN

2018-07-09T10:22:55+00:00 January 18th, 2017|Funding, Supergrid Architecture & System|

PROMOTioN is a 4 years project starting January 2016, with a 40 M€ EU funding, involving 35 Industrial and Academics Participants. It aims to develop meshed HVDC offshore grids on the basis of cost-effective and reliable technological innovation, in combination with a sound political, financial and legal regulatory framework.

A platform for real time modelling & simulation of HVDC electricity systems

2018-07-09T10:22:43+00:00 January 3rd, 2017|Supergrid Architecture & System|

Supergrid Institute is deploying real-time modelling and simulation facilities applied to the analysis of emerging HVDC electricity networks, in collaboration with OPAL-RT. The new platform is aimed at testing and assessing the grid architectures, the control and the protection strategies proposed by our research teams.
