Who Should Take This Course?

  • FIU Electrical and Computer Engineering Students who took EEL4213 (power I) and Graduate Students.
  • Students at other Universities in Florida or out of State with the course’s prerequisites.
  • Engineers and technical personnel in Industry preparing for Engineering License
  • Engineers and technical staff who want to keep current and reach a deep understanding of energy conversion concepts.

OBJECTIVES:

  1. Introducing Electrical Transients in power systems
  2. Cover the concepts of traveling waves and propagation
  3. Modeling of transmission lines as distributed parameter systems.
  4. Discuss issues related to insulation coordination, grounding and limiting of surge effects
  5. Develop techniques related to reflections at transition points in lines and cables
  6. Multi conductor transients and distributed parameter modeling for components and shielding issues.
  7. Involve students in practical experience through the term project.

COURSE TOPICS:

  • Introduction to Electrical Transients in Power Systems (Circuit opening and closing transients, Recovery transients.
  • Traveling waves on Transmission Systems (Propagation of Surges)
  • Modeling of Transmission Lines by Distributed Parameter Concepts (Lossless cases, loss cases, distortion-less cases, Lines with small losses)
  • Distortion due to Corona
  • Energy in Traveling Waves
  • Characteristics of Traveling Waves (wave shapes, standards, impulse, and switching surges, lightning, Basic Impulse Insulation Level (BIL), Flashover surge generators)
  • Analytical approximation of Surge Wave Shapes
  • Transition Points (Lines, Cables, Voltage Buildup, various types of Transition points, terminations)
  • Lumped Series and Shunt Impedance Transition Points (Junctions at Cables, Substations
  • Dissimilar Voltage and Current Surges
  • Surge Arresters (Linear and Nonlinear Characteristics.
  • Successive Reflections on Transmission Systems
  • Grounding
  • Insulation Coordination
  • Multi-Conductor, Multi-velocity Systems
  • Transient Performance of Distributed parameter Systems for Transformer, Generator and Motor Windings
  • Shielding
  • Practical Examples, projects

REFERENCES:
Appropriate lists and copies of technical papers will be distributed or listed for your collection. A list of recent text-books and other technical records will be suggested to you. However, you are also required to research and obtained other pertinent materials related to the topics covered.

ASSISTANCE:
Please try to see Dr. Mohammed during his listed office hours or through the communication forum on the web page. If this proves impossible, a personal appointment should be arranged by calling my direct phone number or the ECE department secretary at extension (305-348-2807).

ABSENCE:
Class attendance (physical or virtual) is very important and is considered in your overall performance in the course. Students are responsible for all material covered in that class.

IMPORTANT RULE:
Students are encouraged to discuss the course topics with the professor and with each other. Any work submitted (Homework, Tests, projects, etc.) should be pledged and signed as the students’ work, and that there is no unauthorized help was obtained. Violators will be subject to academic misconduct, which might lead to dismissal from the university.

GRADING POLICY:
Homework will be assigned regularly, collected, and graded. Efforts in homework indicate that you are studying and caring about the course and, therefore, can have an impact on your final Grade.  Time for the mid-term will be announced one week in advance. Any work submitted must be neat and detailed for a partial mark. Your Grade will be calculated as follows:

Homework and Class Projects 20%
Mid Term 25%
Term Project/Research Paper 20%
Final Exam 35%
  _______
Total 100%

TERM PROJECT:
The project will involve one or more of the topics of this course. The final presentation (oral and written) of the overall project results will be required. Software available for this class can be utilized for the projects.
