A Power System is predominantly in steady state operation or in a state that could with sufficient accuracy be regarded as steady state. In a power system there are always small load changes, switching actions, and other transients occurring so that in a strict mathematical sense most of the variables are varying with the time. However, these variations are most of the time so small that an algebraic, i.e. not time varying model of the power system is justified.
The purpose of this course is to develop a thorough understanding of power system analysis and design as well as the overall capabilities of Power Station. Class room discussion, and problem-solving has been designed to provide the analytical techniques necessary to solve a wide variety of practical problem.


  • Power System Analysis means verifying the adequacy of the power distribution system and it’s components.
  • Recognize coordination related disturbances and outages.
  • Collect the required data to perform a detailed coordination study.
  • Derive complete protective device settings for some of the simpler electrical power
  • systems that are consistent with NEC requirements.
