PROJECT REPORT ON
RELAY CO-ORDINATION
Done at FACT, COCHIN DIVISION

ABSTRACT
The purpose of the protective relays and protective relaying systems is to operate the correct circuit breakers so as to disconnect only the faulty equipment from the system as quickly as possible thus minimizing the trouble and damage caused by faults when they do occur. Relays have revolutionized protection control metering and communication in power systems. Relay co-ordination will help to isolate the faulty region in the power system s ....etc

Abstract
This paper describes modelling and testing of a
digital distance relay for transmission line protection using
MATLAB/SIMULINK. SIMULINK’s Power System Blockset
(PSB) is used for detailed modelling of a power system
network and fault simulation. MATLAB is used to implement
programs of digital distance relaying algorithms and to serve
as main software environment. The technique is an
interactive simulation environment for relaying algorithm
design and evaluation. The basic principles of a digital
distance relay and som ....etc

TRANSFORMER PRO TECTION USING NUMERICAL RELAY
PROJECT REPORT
Submitted by
AMBILY G ASHA V N SHYAMA K
INTRODUCTION
The aim of this project is to analyze and upgrade existing transformer protection system in BPCL Kochi Refinery. Transformers are static devices totally enclosed and generally oil immersed. Therefore, chances of faults occurring on them are very rare. However the consequences of even a rare fault may be very serious unless the transformer is quickly disconnected from the system. This necessitates providing ....etc
