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.
Participation of SuperGrid to the ISH 2017 Conference
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.
Supplying Power to HV (≥10kV) control and measurement boards: a challenge to overcome
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.
Influence of Electric Field on Space Charge Distribution in Alumina-filled Epoxy Resin for Application in HVDC GIS
The present paper deals with space charge in alumina filled epoxy resin for HVDC applications.
Evolution of the Cathode Spot Distribution in an Axial Magnetic Field Controlled Vacuum Arc at Long Contact Gap
The evolution of the cathode spot distribution is an important aspect of the behavior of vacuum arcs controlled with an axial magnetic field.
Measurement and Analysis of Partial Discharges in HVDC Gas Insulated Substations
The measurement of Partial Discharges (PD) in Gas Insulated Substation (GIS) enables to identify and analyse various types of defects that can result in electrical breakdown.
Effective ionization coefficients and limiting field strength of Fluoronitriles-CO2 mixtures
The density normalized Effective ionization coefficients and critical breakdown electric field of the Heptafluoro-iso-butyronitrile (Fluoronitriles), and Fluoronitriles-CO2 mixture are investigated using the steady state Townsend (SST) experimental setup, over a range of the density normalized critical electric field (E/N) from 200-1066 Td (E is the electric field and N the gas density).
Nonlinear Control of a Fully-Fed Variable Speed Pumped Storage Plant
This paper presents the nonlinear control of a Fully-Fed Synchronous Machine based Variable Speed Pumped Storage Plant (FFSM PSP).
Influence of thermal treatment on space charge in alumina-filled epoxy resin for HVDC GIS
A Gas Insulated Substation (GIS) consists of a high-voltage conductor maintained by spacers placed in a metal enclosure filled with a dielectric gas.
