GENERATOR PROTECTION IN BPCL-KOCHI
REFINERY USING NUMERICAL RELAY

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 provide emergency power in the event of a failure of the normal source of energy.
Generator prote ....etc

Unseen Visible Watermarking: A Novel Methodology for Auxiliary Information Delivery via Visual Contents
Abstract
A novel data hiding scheme, denoted as unseen visible watermarking (UVW), is proposed. In UVW schemes, hidden information can be embedded covertly and then directly extracted using the human visual system as long as appropriate operations (e.g., gamma correction provided by almost all display devices or changes in viewing angles relative to LCD monitors) are performed. UVW eliminates the requirement of invisible watermarking that s ....etc

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

ECE 8830 - Electric Drives
Introduction
Current-fed inverters requires a stiff constant current source input - thus are sometimes referred to as CSI (current source inverters or current stiff inverters).

A large inductance can be used to change a variable voltage input to a variable current input.

VSI-inverters and CSI-inverters are dual to each other.
Introduction (cont d)
Power semiconductor devices used in CSI inverters must be able to withstand large reverse voltages. Therefore, power MOSFETs, BJ ....etc

THREE PHASE DUAL CONVERTER
Introduction
Thyristor based three-phase controlled rectifiers are widely used in the industry for controlling dc motor drives. Controlled rectifiers offering power conversion from ac to dc are reliable and have higher lifetime compared to other converters. DC motors have higher torque than ac motors and hence are suitable for variable speed and speed reversing applications requiring high torques. Although the operation of controlled rectifiers is simple, the realization of the converter control circuit is complex i ....etc

speed control of induction motor ppt

A three phase induction motor is basically a constant speed motor so it s somewhat difficult to control its speed. The speed control of induction motor is done at the cost of decrease in efficiency and low electrical power factor. Before discussing the methods to control the speed of three phase induction motor one should know the basic formulas of speed and torque of three phase induction motor as the methods of speed control depends upon these formulas.
