This module aims to introduce you to the principles of operation of power systems, and enhance your knowledge of electrical machinery, power electronics and renewable energy. It will also allow you to consider the interaction between these system components.
A power network typically integrates power generators, distribution grid, transformers, transmission lines, and loads. This module provides you with an introduction to power system structure, and the principles of electrical machines. Moreover, low-carbon energy sources have increasingly contributed to the current power network, and power electronics play a key role in energy conversion. Therefore, the module also provides you with an introduction to renewable energy, and power electronics. Specifically, you will learn the following from this module:
POWER SYSTEMS (30%):
Principles and construction of single-phase transformers, equivalent circuits, efficiency and regulation, open and short circuit tests, connections of 3-phase transformers, and vector groups. Basics of powers, and power flow. Per unit systems and fundamentals of balanced fault level calculations.
ELECTRIC MACHINES (30%):
Principles and construction of DC machines, equivalent circuit, starting and speed control. Principles and construction of induction machines, expressions for speed of rotating field and slip, rotor power balance, torque-slip curve, and modern control techniques.
POWER ELECTRONICS (20%):
Fundamentals of power electronics and converters (AC-DC, DC-DC, and AC-AC etc.), and PWM control.
RENEWABLE ENERGY (20%):
Application of the knowledge of power systems, power electronics and power machines to a variety of renewable systems, such as hydro, photovoltaics, wind, combined heat and power, fuel cells, tidal and marine power plants, and illustration of their operating principles, types, characteristics and comparisons. Overview of electricity generation technologies from new and renewable energy, current contributions and future prospects. fored heat and power, fuel cells, tidal and marine power plants.
