Recommended Prerequisites

Basic knowledge about electric machines and power electronics

Teaching Methods

Theoretical lectures in the black board and with the aid of Powerpoint slides, pictures and videos, for the presentation of the concepts, principles and fundamental theories related to the topics covered in the curricular unit. These lectures include case-studies about the use of electric drives in different areas of application, being occasionally complemented with classes where the simulation tool Matlab/Simulink is used. Laboratory classes to validate the theoretical-practical concepts covered in the curricular unit.

Learning Outcomes

Acquisition of competences for an adequate selection of an electric drive for a given application, and identification of the typical solutions for the most common industrial applications, considering their specificities. Understanding and awareness for the problems associated to the use of inverters feeding the motor and knowledge about the solutions to mitigate them. Finally, it is also aimed to show the state-of-the-art and future trends in the field of electric drives.

Work Placement(s)

No

Syllabus

Electric drives for applications in the cement industry, steel industry, pulp and paper industry and mines. Electric drives for ship propulsion systems, submarines, aircraft carriers and high-speed trains. Electric drives for very high powers. Electric drives for wind generation systems. Traction systems of electric vehicles. Problems inherent to the use of variable speed drives (VSDs): motor insulation efforts; long cable effects; bearing currents and techniques to mitigate them. Efficient operation of electric drives. Electric drives and industrial automation: integration of the VSD in an industrial network; communication protocols between VSDs and PLCs. VSD ladder programming; the VSD as an element of the industrial internet of things (IIoT). Future trends: predictive control of electric drives; predictive control of synchronous reluctance motors (SynRMs).
