Analysis of the causes of wind suction in generator sets

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.

Which approach is best for wind turbine generator fault diagnosis?

Finally, the application of four categories of model-based, signal-based, knowledge-based and hybrid approaches to wind turbine generator fault diagnosis is summarized. The comprehensive review shows that the hybrid approach is now the leading and most accurate tool for real-time fault diagnosis for wind turbine generators.

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.

What are the common faults of a wind turbine generator?

Common faults of wind turbine generator. Generator electrical faults are mainly stator eccentricity, rotor eccentricity, broken rotor bars, and looseness. The main manifestations of generator stator faults are overheating of stator windings, insulation damage, and grounding.

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.

Are wind turbine failures standardized?

This article presents a standardized analysis of failures in wind turbines concerning the main technologies classified in the literature, as well as identifies critical components and trends for the most modern wind farm facilities, which seek greater efficiency, robustness and reliability to mitigate failures and reduce wind turbine downtime.
