Subject Overview:

This subject provides an insight into the basic elements of electrical power distribution systems such as generators, transmission,distribution, and loads. It offers analytical tools for analysis of basic operations of these systems. Problems related to power flow from source to load, practical constrains and solutions will be discussed in detail. The following topics will be covered.

  • Single-phase AC circuits, three-phase AC circuits, power calculation in AC circuits;
  • Transmission Systems: power transmission equations, static capacity limits, stability limit;
  • Synchronous Generator: construction, equivalent circuits in the d- and q-axis, real and reactive power transfer, loading capability;
  • Load Flow: problem formulation, single-machine infinite bus, two- and three-bus systems, numerical solutions, Gauss-Siedel, Newton-Raphson methods;
  • Fault Analysis and Protection Systems: Analytical methods for solving symmetrical (balanced) faults, protection systems;
  • Symmetrical Components: Phase-sequence transformation, derivation of sequence networks, analysis of line to ground faults, double line faults and double line to ground faults;
  • Power System Stability: swing equation, power-rotor angle curves, stability conditions, equal area criterion, critical fault clearing angle and critical fault clearing time, protection systems.
  • Voltage Stability: Angle vs Voltage stability, Reactive power flow and voltage collapse, mathematical formulation of voltage stability problem, voltage stability analysis, preventing of voltage collapse.


On completing this subject the student should be able to

  • Understand the behaviour of the basic components of power systems,
  • Compute power flow in transmission systems,
  • Compute fault quantities, such as voltage, current and power is transmission systems under normal and fault conditions,
  • Ascertain the stability of power systems from operating conditions,
  • Use software tools to simulate and study the steady-state and dynamic behaviour of electrical power systems.
  • One written three hours examination at the end of semester, worth 60%( must pass written exam to pass subject)
  • One mid- semester test worth 15%
  • Continuous assessment of workshops over the semester worth 15%.
  • Projects,Assignments, Reading, and written reports worth 10%.
