EEE3014 : Power System Operation
- Offered for Year: 2019/20
- Module Leader(s): Dr Haris Patsios
- Owning School: Engineering
- Teaching Location: Newcastle City Campus
Semester 2 Credit Value:
To provide students with a systematic understanding of the operation of a modern electricity network, operating under balanced steady-state and fault conditions.
The course is designed to be of value to students who are considering a career in the electricity supply industry or any large industrial user with their own network.
Outline Of Syllabus
1. The Electricity supply system
Requirements of the electricity supply system. Generation, transmission and distribution. Distribution network configurations. Auxiliary systems.
2. AC power & reactive power
Power and reactive power. Complex power, voltamperes. Power factor.
3. Three-phase systems
Revision of three-phase systems, star and delta connections, line and phase variables. Single line representation of a balanced system.
4. Transmission lines and cables
Physical basis of the distributed parameter model, relationship between the physical layout and equivalent circuit parameters of transmission lines and underground cables. Line models (T and pi), short line model, selection of appropriate line model according to line length and load. Line real and reactive power calculations. Maximum line power. Power losses. Calculation of line sending end and receiving end voltages.
5. Power system calculations
The per-unit system, choice of base values. Fault level calculations. Simple load flow calculations.
6. Steady-state stability
Steady-state operation of synchronous machines. Phasor diagram representation of the synchronous generator connected to the infinite busbar. Power / load angle relationships. Steady-state stability limit. Transfer reactance.
7. Transient stability
Generator short circuit transients. Transient stability from the power/ load angle characteristic, the Equal Area Criterion, critical fault clearing angle, line switching, line faults.
8. Control of system voltage and frequency
Control of system frequency; Matching of supply and demand. Advantages of an interconnected system. Control of line voltage, VAr compensation.
Protection requirements for transmission and distribution networks. Components of a protection system. Types of protection relay. Principles of protection, unit protection schemes, non-unit protection schemes.

Jointly Taught With
|EEE8017||Power Systems Operation & Analysis|
Teaching Rationale And Relationship
Knowledge and understanding of electricity networks and issues associated with their operation will be taught via formal lectures and self-guided study material. This will be supported by reflective learning using worked examples to develop awareness and evaluative skills.
Subject specific, cognitive and communication skills will also be developed during the formal lectures and self-guided material. Time management and IT skills will largely be developed through the self-guided material.
The format of resits will be determined by the Board of Examiners
|EEE8017||Power Systems Operation & Analysis||2||N/A|
Assessment Rationale And Relationship
The unseen written examination will provide students with the opportunity to demonstrate their knowledge and understanding of the key aspects of the operation of a modern electricity supply system.
Subject specific, critical and evaluative skills will also be assessed through the written examination. The other key skills will not be assessed, but students will need to utilise these in order to access the self-guided material and prepare for the exam.
The coursework will provide additional opportunities for the student to develop their skills and understanding of the operation of a power system. Furthermore, the coursework will provide timely feedback prior to the examination assessment.
