6 FAQs about [Causes of wind turbine failure]
What is a bearing failure in a wind turbine?
Bearing failures in wind turbines are a major cause of downtime in energy production for unplanned maintenance, repairs and replacements. This failure type is a primary cost and results in higher operations and maintenance (O&M) costs for the energy operator and in higher utility bills for the customer.
What causes a turbine to fail?
Debris Accumulation: Contamination by dirt or particles that can cause abrasion and premature wear. Bearing failures can cause significant downtime and decreased energy output. Comparatively, this failure can lead to some of the highest downtime periods among common turbine issues.
What happens when a wind turbine fails?
If a wind turbine fails, mechanical components, such as the gearbox, bearings, and yaw gear, can weaken and degrade due to moisture over time, risking component failure and an inoperable wind turbine. This requires a service team (if the weather allows). Mechanical failures are costly and time-consuming to repair, and time is money.
Why do wind turbine blades fail?
Multiple requests from the same IP address are counted as one view. A review of the root causes and mechanisms of damage and failure to wind turbine blades is presented in this paper. In particular, the mechanisms of leading edge erosion, adhesive joint degradation, trailing edge failure, buckling and blade collapse phenomena are considered.
What causes wind turbine gearbox failures?
Some of the statistics generated based on this database are made publicly available and this release is an effort to disseminate the database information to a broader audience. According to the latest statistics from the database, the majority of wind turbine gearbox failures (76%) are caused by the bearings.
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.
