KN2. Innovation and Sustainability - Presentation of the High Speed Train TGV M

– DATE & TIME

TBD

– SPEAKER

Didier Frugier after his electrical engineering degree at university of Grenoble (ENSIEG), Didier Frugier started to work for French Railways (SNCF) in 2000 as power semiconductors specialist at Lyon’s locomotives engineering centre. He was in charge of reliability improvement of semiconductors devices with various technologies (diodes, thyristors, GTO, IGBT, Bipolar transistors…) for whole SNCF rolling stock’s power converters. Since 2005, he is located in Le Mans at Rolling Stock Engineering Centre. After many tasks focused in electric traction on rolling stock acquisition or transformation projects and homologations processes, he was involved in resolution of electrical interaction disturbances between rolling stock and power supply, signalling or telecommunication systems (overvoltages, low frequency instability, perturbations due to harmonics…). Since 2023, he is the senior expert of the “Electrical Traction Energy HV Components” Department for electric traction chain and EMC for railway system.

– AGENDA

During ESARS 2024 conference, SNCF will unveil the key innovations of the new French High Speed Trains, “TGV M”, which contribute to a significant reduction in energy consumption. The aerodynamic design of the train plays a crucial role in decreasing drag, leading to lower energy consumption. The optimized motors, coupled with power converters and a high-efficiency transformer, make it possible to improve the overall efficiency of the traction chain by 4 to 5%. Athermic glazing reduces the effect of solar radiation, thus limiting the load on the air conditioning system. Air conditioning regulation, adjusted to the number of travellers, ensures optimal management of the CO2 level and fresh air, contributing to better energy efficiency. These technological advances places TGV M as a leader in the evolution towards more sustainable rail transport. The keynote will be an opportunity to highlight these advances and discuss their positive impact on the environment and the traveller experience.
