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.

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.

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”

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 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.

Electro-thermal simulation methodology for HVDC cable GIS termination

Communications2021-08-11T16:53:04+02:00June 26th, 2019|Appareillage électrique haute tension, Publications, Systèmes de câbles haute tension|

This paper presents a simulation methodology that can be used to evaluate the electric stresses in GIS/cable termination under different operating conditions including polarity reversal and superimposed impulses.

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

Communications2021-08-11T16:53:12+02:00June 26th, 2019|Publications, Systèmes de câbles haute tension|

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.
