Course Name: Digital Protection of Power System

Course abstract

This course is to be prepared to serve as an introductory course for Digital Protection of Power System for post graduate students of various technical institutes such as IITs, NITs, state level government colleagues, deemed universities and affiliated colleges to the deemed universities. It aims to give a comprehensive up-to-date presentation of the fundamentals of digital relays, concept of digital signal processing used in digital relays and various algorithms utilized in digital/numerical relays. It begins with a state-of-the-art survey of theories and methods of digital/numeric relays and phasor measurement units (PMUs) along with IEC 61850 substation and automation protocols. In continuation, it provides a theoretical summary along with examples of real-life engineering applications to a variety of technical problems such as load shedding and frequency relaying, reclosing and synchronizing, protection issues due to interconnection of distributed energy resources in the grid and digital protection of various electrical apparatus such as generator, transformer, transmission lines etc. In this point of view, the said course bridges the gap between the theoretical advances, experimental validations and practical engineering in real life. It covers analytical techniques used in digital relays and application of PMUs in easily comprehensible manners so that academicians and particularly new beginners would not find any difficulty. Further, discussion of various digital relaying schemes for line and equipment protection is one of the unique features of this course. An important part of the course is the sufficient number of examples and problems included in each unit. Some of the problems are dedicatedly difficult for the in-depth knowledge in the topics, however, unrealistic problems are not taken. Aim of this course is to educate the reader and help the student to realize that many of the problems that will be faced in practice will require careful analysis, consideration and some approximations.
