Does wind temperature affect generator vibration

Accordingly, this paper proposes a dynamic model with 8 degrees of freedom to analyze the bearing outer ring fault characteristics of wind turbine generator under the influence of UMP, while also taking into account the torsional vibration in the model.

The effects of vibration cannot be overemphasized when it comes to generating energy via wind turbine. Vibration is one of the major challenges faced by the wind turbine, due to the.

However, most existing WT temperature monitoring methods ignore the fact that various wind conditions can directly affect internal temperature of WT, such as main bearing temperature. This paper analyzes the effects of wind conditions on WT temperature monitoring.

The generator speed loss and the power loss in the wind turbines are modelled considering a novel vibration feature, the ‘Vibration Index’. The vibration index is derived using the time–frequency domain analysis for each accelerometer's data on every axis.

The wind industry faces the issues mentioned above like the high stresses, vibration, torsion and strict noise requirements when operating wind turbines. Modal characteristics of wind turbines are key parameters when researching the vibration issues.

6 FAQs about [Does wind temperature affect generator vibration ]

How does vibration affect a wind turbine?

The effects of vibration cannot be overemphasized when it comes to generating energy via wind turbine. Vibration is one of the major challenges faced by the wind turbine, due to the complexity of the structure and the area of installation.

Why do wind turbine blades vibrate?

Blade vibration is a maintenance issue and can be a threat to the structure of wind turbine during an extreme event (there was reported case that the blade vibrated intensively and collided with the tower of a wind turbine, which cut off the wind turbine).

How does a wind turbine resonant condition affect vibration intensity?

Furthermore, a small difference in characteristics can have a big influence on the vibration intensity when the wind turbine operates close to the resonant conditions. Most of the damping controls proposed were installed in the nacelle for the first mode of the wind turbine, which is low natural frequency.

Why do wind turbines need a vibration control system?

When these things are properly put in place, it will help to reduce unwanted vibration occurrence, eliminate unexpected failure of the wind turbine in operations, and hence sustainable energy generation from wind turbine. Vibration will occur when a structure is dislodged from its location of stable equilibrium.

Does stiffness loss affect wind turbine vibration?

The research indicated that the stiffness loss causes the increase in vibrations of the nacelle and tower. ATMD was applied to the wind turbine to control the vibration in such a situation. The model under active control showed at most 52% peak to peak vibration reduction .

How does wind load affect a wind turbine?

Fluctuating wind loads can cause fatigue failure to blade and tower of a wind turbine. Wind loads brought by extreme events such as hurricanes may damage wind turbines. To research the controlling effects of wind turbines and to lower the risk of failure, the resultant force on a wind turbine needs to be estimated.
