Aims

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.

9. Protection

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.
