EEL 3216 - Fundamentals of Power Systems

Curriculum Designation: Tier II Elective course for electrical engineering majors.

Course Description: Introduction to the fundamentals of energy conversion; structure of power systems and power system components: transformers, rotating machines, and transmission lines. The operation and analysis of power systems are presented.

Prerequisites: EEL 3112

Textbooks/Required Material:

  • Electromechanical Devices, Energy and Power system Analysis, by J. Balda & Z. Yamavee

Course Objectives:

  1. Analyze the performance of a simple power system with a single source and single load. For this,
    • Read a single line diagram and construct a single-phase electrical circuit representation of a three-phase system.
    • Convert delta connections to wye/star connections.
    • Model a load given as a complex power as an impedance.
    • Calculate the phase and line voltages in the circuit.
    • Calculate the current flows and voltage drops in the circuit.
  2. Use the per unit system in circuit analysis. For this,
    • Select an appropriate power and voltage bases.
    • Calculate the impedance and current bases.
    • Adjust bases across transformers, taking into account the turns ratio.
    • Convert electrical quantities from engineering values to per unit values and vice versa.
    • Convert per unit impedances from one base to another.
  3. Analyze the performance of a piece of power apparatus (transformer, transmission line, synchronous machine). For this,
    • Form the electrical circuit model of the device.
    • Calculate the efficiency for various loading levels and power factors.
    • Calculate the maximum efficiency and required loading.
    • Calculate the full-load voltage regulation for various power factors.
  4. Apply design concepts by specifying the parameters of a piece of power apparatus to meet system design criteria (e.g., specify the transformer ratings to meet voltage regulation requirements.)
