6 FAQs about [Fengjun 5 generator failure rate]

How often do generators fail?

Overall, the generator annual failure rate has increased between 5 and 12 operational years. Early generator failures during the first 5 years of operation are mainly due to design, assembly, and manufacturing/serial defect issues. Generator failures during 6–12 years of operation are mainly due to stator, rotor, bearings, and slip ring issues.

What is the annual failure rate of a generator?

While generator annual failure rate is typically around 1%–4% (including full generator and up-tower replacements), the associated downtime is quite long, and replacement (disassemble/assemble) costs are high. Overall, the generator annual failure rate has increased between 5 and 12 operational years.

Do wind turbine failures represent the general failure rate?

According to the results of these studies and analyses, the database of failures experienced is considered to represent the general failure rate in the industry. This paper brings solutions and suggestions for future studies by pointing out risks and the failure situations that wind turbines are exposed to.

What causes a generator to fail?

Under variable working conditions and electromagnetic environments for a long time, the generators are prone to failure. Common failure modes include generator bearing failure, stator failure, rotor failure, and air gap eccentricity.

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.

Are wind turbine failure rates declining?

It is clear that the failure rates of the wind turbines (WTs) now installed have almost continually declined in the first operational years. This is true for the older turbines under 500 kW and for the 500/600 kW class. However, the group of megawatt WTs show a significantly higher failure rate, which also declines by increasing age.
