Summary of Content

-55 This module examines various aspects of power plant generation, commissioning, maintenance and reliability. An understanding of the concepts on power generation, commissioning, maintenance and reliability will be developed. Appropriate analytical techniques will be imparted to the students and they will be encouraged to develop skills to apply them to power plant generation, commissioning and maintenance. Methods to compute power system reliability with redundancy will be developed. Reliability of power grid systems and statistical methods of load forecasting will be developed. In addition, these skills will also be applied for reliability assessment and evaluation for the GCC countries grid. (case studies)

Syllabus

The taught syllabus will cover the following areas: Overview Of Interconnected Power Systems General requirements of power system, description of plant (generators, pilot-plants, operation procedures, lines, cables, transformers, switches, reactors, motors, etc), integration and interconnection of systems. Plant: Diesel and Gas based generating stations, Thermal and Nuclear generating stations: Major components of generating stations, basic functions and operations including turbines, condenser, cooling towers, environment, examples of typical generating stations with their capacities and energy flow diagrams, general and specific operation, shut down and maintenance aspects.

Reliability Evaluation: Techniques and Methods, Computation of fault rates and average repair times for power system equipment, Customer Interruption and Customer hours lost; reliability evaluation of interconnected system.

Learning Outcomes

On completion of this module the student should be able to:1. Develop an outline design for a reliable power generation system (AM1)2. Explain the procedures for power plant commissioning.(AM1)3. Develop maintenance strategies and procedures for power plant after commissioning.(AM1)4. Assess the reliability of HV circuit breakers in power systems.(AM1)5. Analyse an electrical power plant system to determine component and overall system reliability in both stand-alone and interconnected systems. (AM1,AM7,AM8)

Teaching / Learning Strategy

Study pack, study area in design, lectures and tutorials, guest lecturers from industry, Industrial visits to power stations, web based resources are the sources for learning the module. The main teaching method will be based on lectures. The students will be expected to perform directed reading exercises and self-learning exercises on topics related to Power Plant Commissioning & Maintenance. Tutorials will be used to reinforced the module material and to discuss the issues raised by the directed reading.
