 SHE Level 4 SCQF Credit Points 20.00 ECTS Credit Points 10.00 Module Code MHH623556 Module Leader Mohamed Emad Farrag School School of Computing, Engineering and Built Environment Subject Electrical Power Engineering Trimester B (January start)

### Pre-Requisite Knowledge

-5 Electrical Machines and Power Distribution Systems or equivalent

### Summary of Content

-2 This module examines electrical power systems technology. An understanding of power plant systems, power -3 components and their application will be developed. Special emphasis on the interaction and integration of plant is given. The student will apply modern analytical modelling techniques to evaluate the operation and performance of a power system. Power system security and protection issues will be covered.

### Syllabus

-4 The taught syllabus covers the following areas: Overview of interconnected power system: -3 General requirements of power system, description of plant (generators, lines, cables, transformers, switches, reactors, motors, protection devices etc.), power (real and reactive), voltage, current and their relationship, integration and -4 interconnection of system. Modelling of Power System: -3 Line diagrams, per-unit system, introduction to application of models for -4 fault, load, stability and protection studies. Load Flows: -3 Radial and ring feeder load flow calculations, interconnected system load flow analysis, computer-aided analysis. Series and shunt compensation techniques -4 Fault Studies: -3 Types of faults (short circuit, open circuit, balanced and unbalanced), plant representation, symmetrical components, influence of reactors and transformers, fault injection from generators and motors, computer methods. -4 Protection: -3 Function of protection system, design/selection criteria of protection systems, components of protection systems, zones of protection, protection schemes, primary and backup protection, protection of transmission lines/transformers/generators. -4 Stability: Synchronous machine modelling-3 . Instability in power systems, swing equation, machine steady-state and transient stability, equal-area criteria, computer -4 aided models. Power System Control: -3 Frequency, voltage and power control, Load Frequency Control (LFC), Governors, -4

### Learning Outcomes

On completion of this module the student should be able to: 1. Demonstrate an understanding of the concepts and operation of electrical power systems and plant items. 2. Analyse a power system, including the application of appropriate computer-based tools, to determine fault level, load flow, and stability. 3. Critically evaluate the performance of a power system under different types of faults. 4. Design and evaluate a range of protection schemes. 5. Outline and critically evaluate methods of controlling a power system.

### Teaching / Learning Strategy

-3 The university "strategy for learning" documentation has informed the learning and teaching strategy for this module. The module material will be introduced through lectures, while practical exercises, based on the lecture material, will be given to students for their practical sessions. Tutorials will be used to help explain and elaborate on both the lecture material and the practical exercises and provide opportunities for tutor led formative feedback to students. This is detailed as follows; -360b7 Policy of staff access for students, programme and library induction pack and supporting tour, module handbook providing detailed information. -360b7 Support of a module leader and programme leader, in addition to student representatives - these reflect students' views and concerns at staff-student liaison committee meetings and programme committee meetings. -360b7 Underpinning support is provided from central university support services including: online study skills facility, student counselling service, LDC, IT support using e-mail and/or on-line resources). -357b7 Knowledge and skills: the module develops knowledge and skills, and uses tools, techniques and methods which are immediately useful to employers, both in the UK and overseas. -357b7 Strong emphasis in the module on industrial or research projects with direct industrial input into the module, including the use of visiting lecturers and industrial visits. b7 The module is designed with very strong professional emphasis, informed directly by industrial expertise of staff and industrial liaison committees and professional body requirements as appropriate to enhance the career opportunities of the students in industry and academia. b7 The lecture delivery will be enhanced by a variety of forms including, where appropriate, videos, computer based models and other multimedia forms. b7 On line learning materials to be available electronically, discussion boards will be used to encourage teacher and peer-to-peer dialogue on certain topic areas where this form of communication would be regarded as effective. b7 Academic staff and the Learning Technologists will continue to work together to develop and operate the module on GCU Learn to ensure student support and information sharing. b7 Students are provided with formative and summative feedback via a variety of mechanisms. Feedback on coursework is provided within 3 working weeks of submission providing information on strengths, weaknesses and suggestions for corrective action. b7 Student feedback on teaching, learning and assessment will be sought at the end of the semester through a module evaluation questionnaire. -3 -357
