Modeling, Analysis and Estimation of Three Phase Unbalanced Power Network

By Prof. Biswarup Das | IIT Roorkee

Learners enrolled: 769 | Exam registration: 155

ABOUT THE COURSE:
Traditionally, due to aggregation of large number of loads, it has been assumed that the loads drawn from the transmission network are largely balanced. However, due to increasing adoption of electric mobility (AC electric railway, electric vehicles etc.), considerable level of unbalanced loads can be drawn from the transmission network. Therefore, the traditional balanced approach for analyzing a transmission network may not be very effective analyzing an unbalanced three phase power network. In this course, modeling, analysis and quasi-steady state estimation of an unbalanced three phase power network would be discussed.

PREREQUISITES: All compulsory UG courses on Electrical Power System and also the course on “Computer Aided Power System Analysis” available in NPTEL.

INDUSTRY SUPPORT: Any company engaged in Power transmission/distribution as well as any company engaged in development of Power System analysis Software.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 27 October 2024 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Roorkee .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
