Abstract:
Sustainable operation of electric railway systems represents a significant purpose nowadays in the development of high power and high speed locomotives and trains. At present, high speed electric vehicles mostly work with three-phase induction motors or three-phase synchronous motors as traction motors. The two electric machine types have different efficiencies at different operation points, and experience differences with respect to safety, speed and power, energy use and exergy efficiency. An important issue that correlates these aspects is the electromagnetic torque developed by an electric traction motor. Under the vision of sustainable development and industrial ecology, the key points of sustainable operation of electric railway systems nowadays are related to the high electromagnetic torque developed by traction motors, energy savings and environmental impact mitigation, particularly through high exergy efficiency. In order to provide an overview of the sustainable operation of nowadays electric railway systems, an analysis is presented of the electromagnetic torque capability of AC electric motors utilized as traction motors in modern locomotives of high power and/or high speed. The results may enhance understanding that integrating technical and ecological aspects should represent a significant challenge to humanity within the present industrial world, particularly for optimising the safe and sustainable operation of electric railway traction systems.
