6 FAQs about [Wind power generation fault handling measures]

How to detect a fault in a wind turbine?

The fault diagnosis of a wind turbine was performed by comparing the wind turbine behavior predicted by the trained model with the reference space and analyzing the distribution and correlation of the wind turbine SCADA data. However, the fault model was combined with the acoustic signal, which reduced the success rate of fault detection.

Why is a fault analysis important for wind turbines?

The purpose of a fault analysis is to determine the cause of the fault; to clearly understand the nature, location, and reason for the fault; and to take targeted maintenance actions to ensure normal operation of the wind turbine while reducing cost and maintaining efficiency . Therefore, a timely fault analysis is important for wind turbines.

Can wind turbines handle faults with grid-forming control strategies?
