- Transformers: structure and functions of basic components, volts per turn calculation, tap changers, oil/cellulose insulation materials
Power System Analysis:
- AC circuits: impedance, phasors, real and reactive power.
- 3-phase systems: delta and wye connections, line/phase voltage, instantaneous/complex power.
- Per-unit calculations: calculating different bases, converting between bases, equivalent circuits.
- 2-bus power flow: power flow between two busbars, transmission of real and reactive power, load modelling.
- Review of methods for generation of electrical energy in modern power systems.
- Basic concepts of power system protection and protection coordination.
Aims
This course unit detail provides the framework for delivery in the current academic year and may be subject to change due to any additional Covid-19 impact. Please see Blackboard / course unit related emails for any further updates.
The programme unit aims to: introduce the main power system components such as overhead lines, power cables, switchgear and power transformers used in transmission and distribution of electrical energy including their function, structure and design. The unit will also impart the fundamental knowledge required to model and analyse basic electric power systems by introducing the techniques required for power flow, fault calculations and power system protection.
