Electrical Energy Conversion and Transport - entry

This module has been designed to develop the candidate’s basic knowledge of Electrical Energy Conversion and Transport. It gives an introduction into electrical machines including DC, synchronous and induction, and provides an introduction into instrumentation and control techniques. Building upon the previous knowledge gained from the Electrical and Electronic Principles module, the module provides a fundamental course in electrical engineering for the BEng Mining Engineering degree and BSc in Renewable Energy degrees. It is also a pre-requisite for the Network Engineering, Modelling and Management module (3^rd year Renewable Energy only).

This course employs a theoretical, practical and multidisciplinary approach to enable students to develop a broad understanding of electrical machines, measurements and control of electric energy. At the end of this module students will gain confidence in their fundamental understanding, applications and practical knowledge of electrical machines, electrical energy conversion and transport, along with gaining a further insight into instrumentation and control systems.

On successful completion of this module you should be able to demonstrate:
