SuperGrid Institute’s has a significant presence at Jicable19

2019-07-04T11:58:45+02:00June 28th, 2019|Event, HVDC Cable Systems|

This year, for the first time our presence at PCIM Europe 2019, was noticeable with our stand from 6th to 9th May. At the conference, and as power electronics is at the heart of our innovations, SuperGrid Institute was invited to present during the « Smart Transformers » special session.

LISORE consortium plenary meeting at SuperGrid Institute

2019-07-10T11:19:25+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.

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.

SuperGrid Institute involved with the National Congress of Dielectric Spectroscopy

The national congress of dielectric spectroscopy (SDM2) took place at LyonTech on the 6th and 7th of June at the La Doua academic campus. A number of our materials experts attended to present some of the innovative studies that are under way at SuperGrid Institute.

Effect of the Surge Arrester Configuration in MMC-HVDC Systems under DC and Converter Fault Conditions

2019-06-24T10:24:43+02:00June 18th, 2019|Publications, Supergrid Architecture & Systems|

Different surge arrester configurations are studied for a modular multilevel converter (MMC) in a symmetrical monopole configuration. Each configuration is analyzed under fault conditions including DC side faults and faults inside the converter station. The configurations considered are compared in terms of overvoltages, current levels and energy dissipation.
