Advanced Protections System of Substation using Numerical Relays

Abstract

The electrical power substations are important part of the electrical power system, if any fault occur in them it may lead to large damage of equipments and components of substation , also cut the supply of the consumers and perhaps lead to black out. For importance of substation and seriousness of the faults which occur in them, advanced protection systems are applied using numerical relays which have ability to deal with the different types of faults and isolate the faulted parts as fast as possible with high sensitivity in order to secure the continuity of supply and maintain the system stability. In this project full protection is provided to transformer and bus-bar using advanced numerical relays from different types of faults which may occur on them
