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

Numerical simulation of rotor stator interaction is crucial for turbo machinery improvement since it allows the optimization of blade path design In addition the numerical simulation of rotor stator interaction makes it possible to predict the location and variation of hot spots on blades which is extremely useful in the turbine thermal design However simulation of rotor stator interaction is notorious for being computationally expensive To reduce the turnaround time and cost MFLOP a parallel code based on the message passing interface l ....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

ppt on magenn air rotor system

February 27, 2009 Wind power is notoriously flighty, particularly at ground level. Most turbine-on-a-post wind powered generators operate at around 20-40% of their rated generation capacity, simply because wind is intermittent and changes direction. But a generator situated 500-1000 feet above ground level would enjoy much more consistent strong wind - which is why the Magenn MARS system makes so much sense. It's a helium-filled rotating airship that spins in the wind on the end of a variable-length tether that a ....etc
