A5217 - Power System Operation and Control
Objectives
This subject deals with the economic operation of power systems. It emphasizes on load flow studies, single area and two area load frequency control and reactive power control.
Course Outcomes
After the completion of the course, the student will be able to:
A5217.1 Apply the basic knowledge for economic operation, load frequency control and reactive power compensation.
A5217.2 Analyze the static and dynamic performance of single and multi area Load Frequency Control.
A5217.3 Analyzethe techniques and devices used for reactive power compensation.
A5217.4 Evaluate the load scheduling among various thermal and hydrothermal plants.
A5217.5 Model various components of an isolated power system.

Coursework
Inform the instructor any time prior to the due date for an assignment that you wish to use a late day; you may then turn in the assignment up to 24 hours late. Multiple late days may be used on the same assignment. There are no partial late days; turning in an assignment 2 hours late or 20 hours late will both use 1 late day. Note that late days are intended to cover both normal circumstances (you simply want more time to work on the assignment) and exceptional circumstances. The late assignments will receive at most half credit.

Commitments
It is my ultimate goal for this course, and my teaching, to develop your academic skills, advance your learning of electrical and electronics engineering concepts. To do so will require commitments from myself and from you toward meeting this goal.
Active Participation
I will be prepared and on time for class each day, ready to use class time to help you understand the course material. I will respectfully listen to, understand, and answer questions asked in class.
You are expected to attend class and actively participate in discussions every day, answering questions, asking questions, presenting material, etc. Your participation will be respectful of your classmates, both of their opinions and of their current point in their educational journey, as we each approach the material with different backgrounds and contexts.
Constructive Feedback
I will keep office hours and be available for outside appointments, and respond to emails. I will provide feedback on group presentations, exams, projects, and homeworks.
You are encouraged to provide constructive comments for improving this course for furthering your learning throughout the semester. There will be an opportunity for anonymous course feedback at the end of the semester, in which I hope you all participate. Through your feedback I can improve this course and others for future students.
Academic Integrity
I will abide by the above syllabus and grade your work fairly.
- All students have an equal right to their opinions and to receive constructive criticism.
- Students should positively engage the course material and encourage their classmates to do the same.
- No students should gain an unfair advantage or violate their peers' commitment to honest work and genuine effort. It follows that any work that a student submits for class will be that student's own work. The amount of cooperation undertaken with other students, the consistency and accuracy of work, and the test-taking procedure should adhere to those guidelines that the instructor provides.
- Members of the Hendrix community value and uphold academic integrity because we recognize that scholarly pursuits are aimed at increasing the shared body of knowledge and that the full disclosure of sources is the most effective way to ensure accountability to both ourselves and our colleagues.
