6 FAQs about [Abnormal noise from wind turbine generator bearings]

What is a wind turbine generator failure analysis & fault diagnosis?

In this article, a comprehensive and up-to-date review of wind turbine generators failure analysis and fault diagnosis are presented. First, the electrical and mechanical failures of various WTG components, including stator, rotor, air gap, and bearings, are analyzed. Then, the fault characteristics and root causes of WTG are studied.

Can bearing faults be detected in wind turbines?

The proposed method emerges as a robust solution for detecting bearing faults amidst challenging signal environments. Its capacity to accurately diagnose bearing faults, coupled with its proficiency across diverse scenarios, positions it as a potent diagnostic tool for wind turbine systems.

What is the bearing status of a wind turbine?

Bearings are the core components of the wind turbine’s mechanical transmission system, but the bearings of wind turbines are prone to wear and failure during vibration, and it is often difficult to determine the fault-bearing status and fault location. Therefore, the monitoring and fault diagnosis of wind turbine bearing status are very necessary.

How to solve the problem of generator bearing imbalance in wind turbines?

Compared with the existing research, the proposed method can effectively solve the problem of GAN gradient disappearance and gradient explosion, generate high-quality samples, and then balance the data set, effectively solve the problem of generator bearing imbalance in practical engineering wind turbines, and improve the fault diagnosis accuracy.

What causes a wind turbine bearing to fail?

Insufficient lubrication in the bearing of the wind turbine generator will lead to poor heat dissipation of the bearing, which will cause bonding on the surface of various components inside the bearing. When the load is too large, it will accelerate the process of gluing and make the bearing fail. The bearing fault is caused by uneven force.

Is there a spalling fault in the outer race of generator bearing?

A spalling fault was found in the outer race of the generator bearing in this wind turbine. This finding demonstrates the success of the proposed method in identifying generator bearing fault features in wind turbines in a wind farm. Fig. 37. Detected Fourier support for the vibration signal.
