High-speed traction studies need to carry out detailed equations for formalising a complete electromechanical model, representing the dynamic coupling of electrical and mechanical phenomena. Starting from Lagrange and Park theories, and after recalling the general criteria for the set-up of the two distinct mechanical and electrical sub-systems, the new formalisation of a complete dynamic model is presented, with specific reference to a train dedicated to high-speed services. Simulations are carried out in case of three-phase short circuit faults at a speed of 100 km/h. Representative of the dynamics of each single component, the investigation focuses in particular on the components of transmission (rotor, cardan joint, gearcase ) and the relevant torques associated to the short circuit dynamics.

Abstract
High-speed traction studies need to carry out detailed equations for formalising a complete electromechanical model, representing the dynamic coupling of electrical and mechanical phenomena. Starting from Lagrange and Park theories, and after recalling the general criteria for the set-up of the two distinct mechanical and electrical sub-systems, the new formalisation of a complete dynamic model is presented, with specific reference to a train dedicated to high-speed services. Simulations are carried out in case of three-phase short circuit faults at a speed of 100 km/h. Representative of the dynamics of each single component, the investigation focuses in particular on the components of transmission (rotor, cardan joint, gearcase ) and the relevant torques associated to the short circuit dynamics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
