DESCRIPTION - summary of the module content

This module has been designed to develop your knowledge of power electronics and power systems, data acquisition and automation. The future grid will see more integration of renewable energy sources (RES) and, thus, it is vital to understand power electronics, which is the enabling technology for integrating RES to the Grid. You will also learn the basic skills for modelling and analyzing the power network. Additionally, this module will allow you to gain hands-on experience in the practical aspects of data acquisition and control and associated software in the context of power electronic converters. You will have ‘hands-on’ interaction with sensors, data acquisition systems and control equipment. You will then be working in small groups on a chosen project to select sensor components data loggers, and actuators to assemble a data logging and control system for your project that could then be deployed ‘externally’. This is theoretical and practical course using lectures and laboratory-based exercises, and resulting in individual design and group design exercises.

Prerequisite module: CSM2177 or equivalent

AIMS - intentions of the module

The objective of this module is to consolidate and further develop your core knowledge and understanding of electrical power systems engineering, particularly the issues associated with the connection of renewable energy projects to electricity distribution grids. The overall expected level of attainment is a capability of conducting sensible dialogue with specialist electrical engineers that have been commissioned to complete grid connection studies. Furthermore, the module covers data acquisition and automaton which influence the design and operation of power electronic converters.
