This paper presents an overview of the DC-DC power converters dedicated to HVDC proposing a classification based on their structure.
Since 2016, SuperGrid Institute’s program 4 has intensely worked on the specification of a test platform with the capability to go up to 40bars of internal pressure and validate subsea node, a SuperGrid Institute concept for offshore meshed networks. Beside its imposing size, the particularity of this platform is that it allows combined testing functions on subsea high-voltage cable systems including water pressure, di
Multi-terminal high voltage direct current (MTDC) grids, or supergrids, are considered an interesting solution to integrate large amounts of renewable power and release congestion of existing AC power grids. Nonetheless, safe and reliable operation of such grids require the development of new DC protection systems.
Comparison between numerical and analytical methods of AC resistance evaluation of medium frequency transformers : validation on a prototype
In the future, medium-frequency transformers (with a frequency range of 5-100 kHz) will be major components in dc-dc converter applications, for both medium-voltage direct current and high-voltage direct current networks.
Analysis of voltage and current unbalance in a multi-converter topology for a DC-based offshore wind farm
High Voltage Direct Current (HVDC) is increasingly being used for electric power transmission over long distances.
Gate-drive power supplies in medium voltage and high voltage direct current (MVDC / HVDC) applications require medium to high voltage insulation.
The scope of this thesis includes control and management of the Modular Multilevel Converter (MMC)-based Multi-Terminal Direct Current (MTDC).
PhD Swann GASNIER “Decision support framework for offshore wind farm electrical networks: Robust design and assessment under uncertainties’’
Large offshore wind farms will be important players within the future energy landscape. What is the expected benefit for a project is an essential issue from Investor side, considering both technical and economic aspects. Levelized Cost Of Energy - LCOE - is a standard economic indicator which allows to assess the economic viability of a project.
For 40 years, the biannual conference ISH (International Symposium on High Voltage Engineering) has permitted to researchers all around the world to meet and share their research in the high voltage field. The 2017 edition took place from August 28 to September 01 in Buenos Aires, Argentina.
New high-voltage power electronic converters and facilities for transmission grids tend to have multiple power switches at different floating potentials. Moreover, the trend goes towards the use of power switches with higher operating voltages (up to 10kV), in order to reduce the number of switches by system.
