Electrical Energy Conversion and Transport - 2021 entry

This module aims to develop your basic knowledge of topic, by introducing you to electrical machines, including DC, synchronous and induction, and to instrumentation and control techniques. Building upon the previous knowledge you gained from the Electrical and Electronic Principles module,  this is a fundamental course in electrical engineering for the BEng Mining Engineering degree and BSc in Renewable Energy degrees. It is also a prerequisite for the Network Engineering, Modelling and Management module ( third year Renewable Energy only).
 

This course  takes a theoretical, practical and multidisciplinary approach, to enable you to develop a broad understanding of electrical machines, measurements and control of electric energy.  By the end of this module, you will  have confidence in your fundamental understanding, applications and practical knowledge of electrical machines, electrical energy conversion and transport. Furthermore, you will have  an improved insight into instrumentation and control systems.
