Detection of Short Circuits in the Rotor Field Winding in Large Hydro Generator
International Conference on Electrical Machines, 2018A method for detecting inter-turn short circuit in the rotor field winding of a large hydro generator is presented. The proposed method is based on the use of two inductive probes installed at two different locations in the machine, exploiting therefore ...

Diagnosis of wind turbine rotor system
2016 American Control Conference (ACC), 2016This paper describes a model free method for monitoring and fault diagnosis of the elements in a rotor system for a wind turbine. The diagnosis as well as the monitoring is done without using any model of the wind turbine and the applied controller or a description of the wind profile. The method is based on available standard sensors on wind turbines.

Rotor and Wind Turbine Formalism
2017The main conventions used in this book for the study of rotors are introduced in this chapter. The main assumptions and notations are provided. The formalism specific to wind turbines is presented. The forces, moments, velocities and dimensionless coefficients used in the study of rotors are defined.

Prevention of rotor-winding deformation on turbogenerators
Electrical Engineering, 1944During recent years there have occurred several cases of failures on turbogenerators which were found to be due to a singular type of deformation of the rotor windings. It is recognized that the deformation of rotor windings is due to forces set up in the windings by the interaction of centrifugal force and temperature change.1 The purpose of this ...
