This agreement covers lifelong learning, technology research and the provision for scientific and technical proficiency.

25 kV-50 Hz railway power supply system emulation for Power-Hardware-in-the-Loop testings

2019-01-08T10:53:47+00:00January 8th, 2019|Power Electronics & Converters, Publications|

This paper presents a methodology to consider the impedance of a grid in power hardware in the loop (PHIL) experiments to validate power converter control in presence of harmonics or resonances in the network impedance. As the phenomena to emulate are in a large frequency range, the skin effect in conductors has to be taken into account. A procedure is developed to model the network.

PhD Quentin MOLIN “High Voltage SiC MOSFET Robustness study: threshold voltage shift and short-circuit behaviour”

This manuscript is a contribution to reliability and robustness study of MOSFET components on silicon carbide “SiC”, wide band gap semiconductor with better characteristics compared to silicon “Si” material. Those new power switches can provide better switching frequencies or voltage withstanding for example in power converter. SiC MOSFET are the results of approximately 10 years of research and development and can provide increased performances and weight to some converter topology for high voltage direct current networks.

SuperGrid Institute’s project selected for Grid2030

2018-12-06T17:47:18+00:00December 6th, 2018|Event, Supergrid Architecture & Systems|

SuperGrid Institute and IMDEA joint forces with the support of REE, and created a consortium. This consortium was selected from more than 80 projects. Through the "Reduced Inertia Transient Stability Enhancement" (RITSE) project, SuperGrid Institute will strive to improve the transient stability of the AC networks by coordinating the use of batteries and HVDC links.

2018-11-09T13:52:00+00:00November 9th, 2018|Phd, Supergrid Architecture & Systems|

This work proposes a method for the full development, from conception to implementation, of the supervisory control of a multi-terminal HVDC (MT-HVDC) system.

Study of Turn-to-Turn Electrical Breakdown for Superconducting Fault Current Limiter Applications

2018-11-06T16:01:51+00:00November 2nd, 2018|High Voltage Substation Equipment, Publications|

The rational insulation design of a resistive superconducting fault current limiter (r-SCFCL) requires data gathered from experimental setups representative of the final apparatus. Therefore, an experimental study was performed to characterize the electrical breakdown (BD) of liquid nitrogen (LN2) in the peculiar conditions of a quenching superconducting device.

Arc appearance and cathode spot distribution in a long gap high-current vacuum arc controlled by an external axial magnetic field

2018-11-15T16:33:23+00:00October 31st, 2018|High Voltage Substation Equipment, Publications|

An experimental study of a high-current vacuum arc (VA) generated between two static CuCr25 contacts spaced 20 or 30 mm apart was conducted to characterize the arc appearance and the cathode spot (CS) distribution.
