6 FAQs about [Reasons for high generator wind temperature]
What causes wind turbine downtime?
Numerous statistical studies have pointed out that generator failures are a main cause of wind turbine system downtime. The generator, as one of the core components, converts rotating mechanical energy into electrical energy.
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.
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.
Why is a generator important in a wind turbine?
The generator is the key part for energy conversion in the wind turbine drive train. With large wind turbines, the generator safety and stability during operation have become urgent issues to address. For head mass reduction, the generator structure is usually complex.
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 factors affect the performance of wind turbines?
Variation in voltage fluctuation or variation in speed between high-speed shaft and low-speed shaft varies the rotation of wind turbines. Other parameters such as encoder failure, sensor failure and software failure also affect the performance of WTGs.
