ECEN 4167 - Energy Conversion 2

Catalog Data ECEN 4167 (3). Energy Conversion 2. Studies the derivation of the dynamic equations of motion of electromechanical systems, linear and rotary motion machines based on variational principles and basic force laws. Looks at equivalent circuits in abc and dqo coordinates for Ac and Dc machines. Discusses conditions under which an electromagnetic torque can be produced. Applies theory to the most important modes of steady-state and transient operation of electrical energy converters.
Credits and Design 3 credit hours. Elective course.
Prerequisite(s) ECEN 3170, Energy Conversion 1
Textbook Notes.
Course Objectives Understanding of the elements and concepts of variable-speed drives and their potential for energy conservation and increasing the efficacy of industrial processes. The theory, open- and closed-loop control, and application of DC motors to real-life applications, where controlled currents, torques, forces, speeds and positions are required. Emulate the performance of DC machines when controlling induction machines, leading to vector and direct torque control.
Topics Covered
  1. Elements of power semiconductor drive including mechanical loads, power sources, and control components
  2. Commutation of DC motors
  3. Rectifier control of DC drives
  4. Generation of closed-loop control of DC drives
  5. Principles of induction motors
  6. Steady-state performance of induction motors fed by AC voltage controllers, voltage source, and current source inverters
  7. Speed and torque control based on proportionality of V-voltage and frequency, and of E-induced voltage and frequency.
