SuperGrid Institute is going global! Next week, Arthur Boutry will be crossing the Atlantic to collaborate with the Center for Power Electronics Systems (CPES), a laboratory at Virginia Tech (listed by The Times as one of the top 300 universities in the world in 2019!). During his time in the USA, Arthur will continue his work on designing MMC sub-modules for HVDC applications as part of his PhD which he began in 2018 at SuperGrid Institute, in collaboration with the Laboratoire Ampère. Arthur received a grant from the American government for his exchange year in the form of a Fulbright scholarship, one of the most prestigious and competitive fellowship programs in the world. An impressive accomplishment!

SuperGrid Institute hosts the 11th Quarterly review of NanocompEIM 2

Since October 2016, SuperGrid Institute has been involved in the NanocompEIM 2 project. The goal of the project is to develop nanocomposites (Nanocomp) for electrical insulation materials (EIM) in order to reduce CO2 emissions and improve system reliability and availability. Financed at 50% by Innovate UK, a government organisation dedicated to research and innovation in the United Kingdom, the overall budget of the project is around 1M£ (1.1M€).

SuperGrid Institute collaborates with Edouard Branly School’s undergraduate students for their end of year project!

2019-07-26T09:39:54+02:00July 18th, 2019|All|

Last year, SuperGrid Institute signed a framework agreement with the Digital Department of Edouard Branly School with the aim of developing educational modules in the field of electrical engineering. This year for their final project the undergraduate students from the Digital Department worked on an interactive learning application based on High Voltage Direct Current cable systems and junctions. The final project counts for a significant proportion of the students’ overall credits for the year.

Michel MERMET-GUYENNET’s keynote speech at PEDS 2019

2019-07-26T09:39:55+02:00July 12th, 2019|Event, Power Electronics & Converters|

This Tuesday the 10th of July, Michel MERMET-GUYENNET presented a keynote speech at the 13th IEEE International Conference on Power Electronics and Drive Systems (PEDS 2019) in Toulouse, following the invitation of Bernado COGO from the Antoine de Saint Exupéry Institute of Technology (IRT Saint Exupéry). In his paper, Michel MERMET-GUYENNET presented power electronics technologies for MV and HV grids.

Phd Priscillia DANIEL “Electrical properties study of cross-linked polyethylene insulated cables in presence of gaseous cavities aged under DC or DC with harmonic voltages”

2019-07-26T09:39:55+02:00July 5th, 2019|HVDC Cable Systems, Phd|

This study aims to examine possible impact of these harmonics in presence of microcavities. Depending on their size and on the electrical field, partial discharges (PD) can occur in these microcavities. Two types of cables have been aged: a medium voltage AC (MVAC) cable with millimetric cavities induced artificially and a model cable with an HVDC XLPE grade.

SuperGrid Institute’s has a significant presence at Jicable19

2019-07-26T09:39:56+02:00June 28th, 2019|Event, HVDC Cable Systems|

Jicable is an international forum relating to insulated power cables and accessories, ranging from low voltage and special cables to ultra-high voltage cables and new technologies. The forum provides the perfect environment to exchange information on progress in research, industrial development, cable installation, operation & diagnoses. SuperGrid Institute was highly involved in this 10th edition of the conference, with 4 presentations and 1 participation as a “rapporteur”.

SuperGrid Institute’s participation at AGP21

2019-07-26T09:39:56+02:00June 27th, 2019|All, Conference, Event|

The Association Grand Projects 21 – Major Programmes and Projects for the 21st Century (AGP21) met this Thursday in Versailles to discuss the development of interconnected electricity networks on a global scale. SuperGrid Institute was invited to present its vision and discuss the appeal of multi-terminal HVDC technologies in the design and construction of future energy highways. The subsea node concept developed at SuperGrid Institute was also introduced as an essential building block for extending offshore networks and integrating renewable energies on a wide-scale.

LISORE consortium plenary meeting at SuperGrid Institute

2019-07-26T09:39:57+02:00June 26th, 2019|All, Event|

SuperGrid Institute was pleased to host the LISORE consortium plenary meeting this Wednesday. This 15-month project that began in January 2019 aims to explore the feasibility and develop a technological roadmap from which innovative low-cost substations can be developed, thereby enabling the integration of marine energies by 2025. By participating and organising this day, SuperGrid Institute has increased its visibility and positioned itself as an expert partner in the domain of innovative electrical systems. The visit of our test platforms enabled us to demonstrate to the project participants how we are supporting the development of the sector through our expertise and state of the art facilities.

Follow up of space charge distributions in HVDC cable during a Pre-Qualification test using the Pulse ElectroAcoustic technique and the Thermal Step Method

2019-07-26T09:39:57+02:00June 26th, 2019|HVDC Cable Systems, Publications|

In order to better understand the evolution of space charge and electric field distortions during the application of electro-thermal stresses to a HVDC cable system, the present paper shows the follow up of periodic space charge characterizations on a HVDC cable during part of a Pre-Qualification test using both the Pulse ElectroAcoustic technique and the Thermal Step Method. The focus is on the evolution of space charges distributions during load cycles and high load sequences according to the Cigré TB496 recommendation.
