6 FAQs about [The turbine generator wind temperature is too high]

Why are high-speed generators affecting wind turbine design?

This is the main reason high-speed generators have continued to have such an impact on turbine design, especially for onshore applications. Wind turbine generator failures are one of the primary reasons for increased operations and maintenance (O&M) costs and generation asset downtime.

What happens if a generator runs at a higher temperature?

Generator operating at higher temperature leads to increase DE and NDE operating temperature. Higher bearing grease temperature reduces bearing and grease service life. Bearing and grease will be impacted more depending on which side bearing facing higher operating temperature.

What causes a wind turbine generator to fail?

Bearing failure is one of the most common reasons for the downtime associated with wind turbine generator failure. There are two aspects of the investigation that is, prevention and detection. Vibration measurement is the most commonly used bearing conditioning monitoring technique ( Tandon and Choudhury, 1999 ).

Can a wind turbine operate at Extreme temperatures?

Various methods have been developed for advanced cooling as mentioned in Kilbourne and Holley (1956) and Singh et al. (2018). With the advancement in High-temperature superconductor technology, the generators can operate at extreme temperatures for a wind turbine of nearly 10MW ( Jeong et al., 2017 ).

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.

Why do wind turbines have a low cooling capacity?

Development of recent high-efficiency generators and motors leading their designs with less cooling capacity. Bearings are one of the most stressed components in the generator. Recent studies have indicated that bearing failure is the prime cause of generator failure, in wind turbine application.
