EE3123Introduction to Electric Power Systems

What you will study

Course overview and aims

To introduce (i) the general structure of power distribution and delivery systems in modern society; (ii) the operating principles of the key components of a power system; (iii) operational issues including power flow, faults and protection; and (iv) current development and future trends in power systems.

Keyword syllabus

Key components of a power system: synchronous generators, transformers, rectifiers, transmission lines, and loads. Distribution in AC electrical power systems, high-voltage DC transmission, microgrids. Three-phase system: balanced and unbalanced systems, symmetrical components, the “per-unit” system, active and reactive power, power factor, power quality, faults and fault current calculation. Transformer: coupled inductors, general transformer model, power transformer, rating, construction. Transmission: underground and overhead lines, short- medium- and long-distance transmission lines, transfer characteristics. Power flow analysis: DC and AC power flow models, power balance, voltage and frequency variations, stability analysis. Robustness and protection: cascading failure, outage, load shedding, restoration. Development and trends: Centralized versus distributed energy sources, renewable sources, energy harvesters, nuclear power, energy storage and conversion, smart grids.
