Power Systems Stability control and Protection

Module Title - Power Systems Stability control and Protection
Number of credits – 20

Module description

This module deals with power system stability, control and protection problems and associated advanced analysis and design techniques.

The module covers synchronous machine theory and dynamic modelling; synchronous machine parameters for dynamic models; synchronous machine dynamic representation in stability studies; small signal stability and control of a single-machine infinite bus; method for the analysis of small signal stability and control of multi-machine systems; control concepts such as Excitation Control and Power System Stabilizer  (PSS); basic concepts and protection principles of power systems such as over current, distance, busbar, transformer and generator protections; analytical calculations, settings and coordination for power system protection; and advanced protection concepts and methods such as Intelligent Electronic Devices (IED), Smart Substation, IEC61850, System Integrity Protection Strategies.

By the end of the module you will be able to:

  • Explain synchronous machine theory and dynamic modelling
  • Derive synchronous machine dynamic models in stability studies
