MODELING RELAYS FOR POWER SYSTEM
PROTECTION STUDIES

by
SANDRO GIANNY AQUILES PEREZ


ABSTRACT
Numerical relays are the result of the application of microprocessor technology in relay
industry. Numerical relays have the ability to communicate with its peers, are
economical and are easy to operate, adjust and repair. Modeling of digital and
numerical relays is important to adjust and settle protection equipment in electrical
facilities and to train protection personnel. Designing of numerical relays ....etc

GENERATOR PROTECTION IN BPCL-KOCHI
REFINERY USING NUMERICAL RELAY

PROJECT REPORT
Submitted by
AJU.M.PAULOSE BUOY THOMAS HAPPY VARGHESE RONY ITTAN SUJITH.S
INTRODUCTION
The aim of this project was to analyze and upgrade the existing generator protection system in BPCL-Kochi Refinery, Kochi. Power generation occupies the prime place in power system. Industrial and commercial power system may include generator as a local source of energy. These generators supply all or part of the total energy required or they provid ....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
