Dual rotor wind turbine
This article describes a a dual rotor wind turbine that is efficient in capturing kinetic energy from wind.
A dual rotor wind turbine includes the following parts :
-a rotatable drive shaft
-a first rotor assembly connected to the drive shaft
-a second independently-rotating rotor assembly coupled to the drive shaft
-, a first stage generator coupled to the drive shaft
-a second stage generator operatively connected to the second rotor assembly
-a housing to keep the turbines
-, a rotary base
-a tail

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

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 ....etc

Investment Casting a Turbine Rotor

presented by:
Tejas Jadhav

Guided by-
Prof. P.G.Kulkarni

abstract:-

Investment casting is an industrial process based on lost-wax casting. Investment casting is an advanced metal forming process used to produce metal parts in high quality, functionality and cost-effectiveness. Lost wax casting process is a one-to-one process in which one disposable pattern produces one metal part. When combined with modern production knowledge a ....etc

GENERATOR FIELD WINDING SHORTED TURN DETECTION TECHNOLOGY

EFFECTS OF SHORTED TURNS IN ROTOR WINDINGS

The impact of operating a round rotor generator with rotor winding shorted turns depends upon many factors1. If the percentage of total turns shorted out is small, the generator may be able to run at rated load for years without further problems. However, larger shorted turn percentages can cause operating conditions that may limit unit loads. If the proble ....etc
