Description
This module allows students to develop the knowledge, skills and knowhow that are necessary to specify and assess the requirements for the traction system for a particular type of train, the specific topology of the line or network to be served and the associated service pattern. The module covers the arrangements for the supply of energy to the train from a national grid or another power source, e.g., diesel, hydrogen or, battery etc., the onboard control and conditioning of the power to be supplied to the traction machines, the facilities for storing energy onboard and trackside, as well as the transmission of traction and braking forces. The module also deals with the fixed infrastructure needed to convert power from a national grid and to distribute it to AC or DC trains, using either overhead or ground-level electrification. Students learn to dimension both traction and braking systems to achieve the necessary acceleration and deceleration rates, creating digital models to validate the choices made. They acquire the knowhow to review the safety and sustainability of traction systems and supplies.
The module is delivered through standard and interactive lectures, case studies, interactive lectures, and team activities provided by University staff, to develop knowhow and skills, with support from guest lecturers from industry and other relevant educational establishments.
Learning Outcomes
By the end of the module students should be able to:
Evaluate different drive train arrangements for their efficiency and environmental acceptability, with a clear focus on economic sustainability;
Identify and model digitally the power and energy requirements for a particular train, as well as its duty cycle and service specification and provide a robust justification for the choice;
Select the appropriate prime mover, power source and, where required, the type of power transmission system that are necessary to provide the specified performance for a given context;
Create a model of a train and its operation and simulate the power use, efficiency and performance of the traction and braking systems;
Choose appropriate sensing, monitoring and control tools and algorithms to ensure efficiency and the safe operation of infrastructure and trains;
Identify and mitigate the risks to systems and their environment that are associated with electro-mag¬netic fields, as well as manage electrical hazards due to touch voltages and similar effects.
