Continuité de service d'une chaîne de traction ferroviaire asynchrone répartie

Abstract : This study focuses on the benefits that can be induced by a Distributed Induction Machine Railway Traction. This is obtained through the additional degrees of freedom it provides, on the one hand across the cooperative controls of the multi-converter/multi-machine systems which constitute the distributed traction and on the other hand by exploiting the Natural Structural Redundancy available in this system. The main objective we want to reach through these two aspects, cooperative controls and structural redundancy, is to ensure service continuity of the distributed railway traction. This study leads to design a supervising automaton which allows ensuring service continuity of the studied system in the case of external disturbances by making the necessary adjustments and drive control commutation. The analysis of cooperative controls leads to the improvement of the Average Differential Control and to propose a new anti-slip strategy. The structure redundancy advantage of a multi-converter/multi-machine system is used in order to compensate the speed sensor fault. Finally, the different strategies which have been proposed are experimentally validated on a test bench that emulates a traction bogie composed by a dual-inverter/dual-motor system.
