Generator wind temperature affects vibration

Rolling bearings play a critical role in wind turbine generators, operating continuously in an electromagnetic excitation environment. Their fault vibration characteristics are affected by unbalanced magnetic pull (UMP), which has received little attention in previous studies.

In this paper, we propose to use a novel feature, the vibration index, derived from the vibration data, to understand the power loss in wind turbines. The methodology adopted in this work involves modelling the gearbox health as the loss of generator speed using a data-driven methodology with vibration index as input.

This research work focuses on a compressive review of the effects of vibration occurrence on wind turbine during energy generation operations and its economical challenges’.

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.

It is crucial for regulating vibrations and offering stability, structural integrity, and support to different components of wind turbines. This explains the importance of controlling vibrations.

6 FAQs about [Generator wind temperature affects vibration]

How does vibration affect wind turbines?

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. This research work focuses...

Why is vibration a limiting factor in wind turbines?

Vibration in wind turbines remains a significant limiting factor in their design, installation, monitoring, and maintenance, especially for larger turbines. Typically, turbine vibrations are characterised in terms of in-plane (flapwise) and out-of-plane (edgewise) modal deformations, as illustrated in Fig. 6 (a-b).

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.

Does wind turbine vibration control extend the lifespan of wind energy generators?

Concluding remarks Extensive research in wind turbine vibration has facilitated advancements in wind energy generator technology and extended their lifespan. This paper reviews recent progress in dynamic and vibration control strategies, providing detailed insights into each turbine component, with a particular emphasis on developments since 2015.
