Course Objectives:

Upon completion of this course, every student should have gained:
  • An understanding of: (a) the equipment needed for transmission of bulk electric energy at low frequencies (60 Hz.), (b) rotating machines for electromechanical energy conversion and (c) basic methods of analysis for the interconnected power system.
  • An appreciation of the engineering requirements of the power system, and in particular, the complexity and tremendous size of the system needed to meet demand reliably and economically.
  • A broad (if superficial) familiarity with the contemporary technological and societal issues of the electric power system, including such issues as: new approaches to the overall system infrastructure, alternative fuel sources, deregulation, social obligation to serve and environmental impact.

Grading

Homework and Quizzes - 20%
Laboratory Exercises - 10%
Midterm Exams - 40%
Final Exam - 30%

Course policies (IMPORTANT: PLEASE READ)

  1. There may be occasional quizzes given without warning whenever I see that they will be useful.
  2. Homework will be posted on my website and you should check for the latest assignment. This avoids the problem of me forgetting to give out the assignment. You must do the homework and laboratory exercises to pass this class. Not completing or very poor attempts at 3 or more assignments will result in a failure for the homework and lab requirements and thus, failure for the course.   
  3. The exams will be closed book but I will include an equation sheet.
  4. Finally, the Department of EECS strongly enforces academic integrity. This class allows, even encourages, you to work together in groups on the homework and labs but each individual must hand in their own work. Exams, of course, are entirely independent affairs. Any instance of cheating will result in failure for the course for all involved parties.
