CONTROLLING GENERATOR SET VIBRATION TO MINIMIZE
the generator/base combination''s interface with the rest of the structure. Minimizing generator set vibration can both reduce the transfer of energy to building structures—that is, the dynamic
6 FAQs about [Generator wind temperature and vibration]
How accurate are vibration signals in wind turbine generators?
Evaluation of the bearing in horizontal, axial, and vertical, with an accuracy of 91%. Non-stationary vibration signal in the absence of an external hardware sensor. Acoustic and vibration signals for different fault cases for gearbox in Wind turbine generators, with hybrid ensemble is developed by stacking the RF, DT, KNN.
Why do generator end windings vibrate?
The vibration of generator end windings has been a topic of concern since the beginning of power generation. Current flowing in the rotor and stator give rise to magnetic fields. The resulting forces lead to vibration within the stator core, but more seriously at the stator end windings and their support structures.
Can resonant vibration cause a generator end winding failure?
resonant vibration condition can lead to movement and forces that can compromise the stator bar insulation and possibly cause a complete failure of the generator. Currently, there is not a set of established industry standards or acceptance criterion for generator end winding vibration.
Is there a standard for generator end winding vibration?
Currently, there is not a set of established industry standards or acceptance criterion for generator end winding vibration. There are many differing points of view within the power industry concerning the sources of vibration, methods of analysis, and solutions.
Can a vibration sensor detect a wind turbine fault?
Currently, the state of the art in wind turbine fault detection is limited to vibration as the sole variable. However, vibration sensors can only detect 5–20% of torsional vibration in the drivetrain, caused by the dynamic and natural frequency of the system .
How do we classify a wind turbine generator?
During feature extraction, vibration comparison was used to evaluate the behavior of the wind turbine generator (WTG) and classify it into three categories: 0 for normal operation, 1 for gearbox failure, and 2 for bearing failure. The evolutionary information consisted of a matrix of “n" events with three classifications.
