New relaying concepts

Chapter

Abstract

The fundamental ideas in protection have developed over many years and there is now a settled understanding and a maturity of approach to power system protection. This however does not mean that new ideas cannot find application in protection work. In recent years, advances in information technology (IT) have given the impetus to protection engineers to reexamine the way protection is practised and to seek to learn and benefit from the new technologies. This process is slow as protection engineers need to be reassured that the traditionally high reliability of relaying systems is maintained and that any benefits that new technologies bring are not accompanied by new and unexpected shortcomings. Therefore, some of the ideas presented in this chapter have not as yet found widespread practical application. They are however in the forefront of considerations as the new generations of relays are designed initially at the conceptual level and eventually through to prototyping and manufacture.
