TECHNIQUES FOR ONLINE DETECTION OF SHORTS IN TURBINE GENERATOR ROTOR

CAUSES FOR SHORTED TURNS
COIL FORESHORTENING
END-STRAP ELONGATION
FOREIGN MATERIAL CONTAMINATION
BLOCKING PROBLEMS

1.COIL FORESHORTENING
BODY CU CANT EXPAND FREELY
MINIMISE BY USING MATERIALS WITH
SUFFICIENT YIELD STRENGTHS

WHY DETECTION IS IMPORTANT
ROTOR UNBALANCE
VIBRATION
HIGHER FIELD CURRENT IS REQUIRED
HIGHER TEMPERATURE WILL RESULT
DIMINISHED CAPACITY

Micro turbines are becoming widespread for distributed power and combined heat and power applications. They are one of the most promising technologies for powering hybrid electric vehicles. They range from hand held units producing less than a kilowatt, to commercial sized systems that produce tens or hundreds of kilowatts.Part of their success is due to advances in electronics, which allows unattended operation and interfacing with the commercial power grid. Electronic power switching technology eliminates the need for the generator to be syn ....etc

ADVANCED ELECTRIC GENERATOR & CONTROL FOR
HIGH SPEED MICRO/MINI TURBINE BASED POWER SYSTEMS

INTRODUCTION

High-speed micro-turbines and mini-turbines play a significant role in the Distributed
Power Systems that provide dependable electric power close to the user. Several high-speed
turbo-generators manufactured by various corporations are now available in the 30 kW to 90 kW
range. These systems operate at speeds from 50000 RPM to 120000 RPM. The generator is
directly coupled to the turbine ....etc

hello,i am final year student of electrical and electronics engineering
i want to do a mini project on technique for on-line detection of shorts in fields of turbine generator rotor.
what are the shorts and how they occur in turbine generator rotor.
and how to apply this technique , where we can apply this technique,and what are the tools used in this project.
so mail me the complete details of this topic to do as a project as soon as possible

A technique for on-line detection of incipient faults in the windings of turbine - generator rotors has been developed based on the twin signal sensing method. To detect the developing shorts in any winding, two identical pulses are applied to both ends f the winding and are reflected back .Any abnormality in the winding results in the applied signals being reflected through nonsymmetrical circuits. The difference between the reflected signals are amplified and used as signature signal for further processing. This paper describes the developmen ....etc
