Online Courses: Power Systems Protection (NPTEL-INDIA)

Reliability of electrical energy systems to a large extent is a consequence of the reliability of its protection system. Basic building blocks of the protection system are fuses, overcurrent and distance relays and differential protection schemes. In this course, we will introduce their principles and applications to apparatus and system protection. 
Technology of relaying has changed significantly in last century. The first generation of relays was electromechanical devices. The second generation involved solid state relays. The present generation of numerical relays are realized by digital signal processing.. In this course, we will also introduce both theory and practice of the numerical relays.
The course can be used as a first course in power system protection. It should be also useful to graduate students, practicing engineers as well as the research community.

Objectives:
In this course, we plan to teach the following: 

1. Fundamental principles of fuse and overcurrent protection and application to feeder and motor protection.

2. Fundamental principles of distance relaying and application to transmission system protection.

3. Fundamental principles of differential protection and application to transformer, busbar and generator armature winding protection.

4. Role of Current and Voltage transformers in power system protection.
5. Relay co-ordination in transmission and distribution system.

6. Introduction to Numerical relaying. DSP fundamentals like aliasing, sampling theorem, Discrete Fourier Transform and application to current and voltage phasor estimation.

7. Numerical relaying algorithms for overcurrent, distance and differential protection with application to transmission system, transformer and bus bar protection.

    Power protection is currently at the forefront of each business's secure communication set ups not like the backup plan it accustomed be. Integrated UPS (Uninterruptible Power Systems) and standby generators make sure the system is regularly running that is imperative with the announcement of a possible energy crisis that's expected by power consultants.

    If two-factor authentication isn’t enough security for you, take stock of the backup email address you use for all of your online accounts. Consider using one or several unique email addresses as password recovery addresses. Just make sure that you never give out these email addresses for personal mail and that they aren’t similar to your other accounts.To see more details to go:complete online protection

    I appreciate that you produced this wonderful article to help us get more knowledge about this topic.
    I know, it is not an easy task to write such a big article in one day, I've tried that and I've failed. But, here you are, trying the big task and finishing it off and getting good comments and ratings. That is one hell of a job done!
