TITLE Electrical Power 1

 
UM LEVEL 02 - Years 2, 3 in Modular Undergraduate Course

 
ECTS CREDITS 5

 
DEPARTMENT Electrical Engineering

 
DESCRIPTION - The Per Unit System: Revision of 3–phase systems; Definition of Per Unit System; Representation of Component Specifications in pu; Changing between different bases.

- Power Transfer in Power Systems: Load Flow Problem; Balance of Powers; Synchronous Generator in Steady State Operation; Synchronous Generator Excitation systems; Performance Chart.

- Transmission Lines: Overhead Lines; Corona Discharge; Insulator Types; Underground Cables; DC Cables; Equivalent Circuits.

- Fault Analysis: Types of Fault; The Fault MVA Source; Symmetrical Faults; Limiting the Fault Level.

- Power System Protection: Protection Relays; Overcurrent Protection; Unit Protection; Distance Protection.

Study-unit Aims:

This unit covers the principles of the components that make up an Electrical Power System. It deals with the p.u. method, steady-state operation of synchronous generators, transmission lines, symmetrical faults and the basics of power system protection.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:
- Explain the principles of operation of synchronous generators.
- Understand how to use the p.u. method in power systems.
- Understand and explain the power flows in transmission lines and how these are modelled (short, medium and long).
- Explain and analyse symmetrical three phase faults.
- Understand the basics of protection in power systems.

2. Skills:

By the end of the study-unit the student will be able to:
- Perform calculations related to synchronous generators and derive their performance chart.
- Perform p.u. calculations applied to power systems.
- Calculate power flows in a power system.
- Perform calculations related to symmetrical three phase faults in power systems.
- Set the parameters of basic power system protection.

Main Text/s and any supplementary readings:

- Power System Analysis, John Grainger, Jr., William Stevenson.
