BEng Electrical and Electronic Engineering

The unit is divided into four main topics.

1. Power Flow Analysis

i)   Introduction to the power flow problem. Review of nodal analysis and production of the admittance matrix

ii)  Nodal analysis for power flow, power balance, type of buses

iii) Three-bus example, implicit/explicit equations, introduction to Newton-Raphson

iv) Newton-Raphson for power flow, multiple-bus power flow, generalisation to N buses, Jacobian matrix, applications of the power flow

v)  Reactive power and voltage control in the context of power flow analysis.

2. Power System Control

i)   Introduction to generation, generation control and frequency regulation, frequency regulation intervals (primary, secondary and tertiary)

ii)  Primary regulation, turbine-governor control, frequency response to changes in load, area frequency response characteristic

iii) Primary regulation, control models (generator, load, prime mover, governor)

iv) Primary regulation, control models (droop, tie-line, interconnected areas)

v)  Secondary regulation, automatic generation control, area control error

3. Asymmetrical faults

i)   Theory of symmetrical components

ii)  Development of sequence networks

iii) Asymmetrical fault analysis

4. Power System Stability

i)   Introduction to power system dynamics, classification, dynamic effects, definitions

ii)  Power system stability problems/types, swing equation, types of rotor angle stability

iii) Equal area criterion, critical clearing time, improving stability

The course unit aims to: Prepare students for a career in electrical power engineering. It covers a spectrum of important aspects of electrical power systems analysis and operation. Produce graduates with a systematic knowledge and understanding of the mathematics and engineering science required for the analysis of electrical power systems. Develop the analytical and practical skills appropriate for a career in electrical power engineering. Equip students with the knowledge and skills needed to design and analyse electrical power systems that are fit for purpose, cost effective, compliant with relevant legislation, safety criteria and environmentally sustainable.

On the successful completion of the course, students will be able to:

ILO 1: Select appropriate data for different types of power system studies and explain the impacts of variations in parameter values on the outputs of the studies.

ILO 2: Describe the models and control schemes used for frequency containment in interconnected power systems and perform frequency disturbance calculations.

ILO 3: Perform hand-based large-disturbance rotor angle stability analysis of single machine power system models and synthesise knowledge about the underlying stability mechanisms to explain how the stability will be affected by changes to the system.

ILO 4: Formulate and solve power flow for a simple power system model using hand-based and computer-based methods.

ILO 5: Describe the basic control and operational processes within power systems and how they are used to keep the power system within acceptable limits and to ensure system security and stability.

ILO 6: Perform unbalanced fault analysis on simple power system models by hand and explain the assumptions and conditions for which the results are valid.
