Definition and overview of Vertical Axis Wind Turbines (VAWTs) The overview and definition of VAWTs can help us understand how these turbines function. A vertical-axis wind turbine (VAWT) is a type of wind turbine
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
5 天之前· In many countries, wind turbines have proven themselves to be a great solution as renewable energy [1].Though there are other resources of renewable energy which involves
The proposed solution can: (1) predict the remaining useful life (RUL) of wind turbine generators before a fault occurs and (2) diagnose the state of the wind turbine generator when the fault occurs.
The risk of oscillation of grid-connected wind turbine generators (WTGs) is well known, making it all the more important to understand the characteristics of different WTGs and analyze their performance so that
As the running time of a wind turbine generator unit (WTGU) increases, the ageing and wear of its components will be aggravated gradually, which leads to deterioration of its operation condition. In order to ensure the
Working of Wind Power Plant. The wind turbines or wind generators use the power of the wind which they turn into electricity. The speed of the wind turns the blades of a rotor (between 10 and 25 turns per minute), a
To improve the reliability and optimize the maintenance strategy of a large-scale wind farm, a health condition assessment method of wind turbine generator system (WTGS) based on multiple turbines cooperation is
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.
The dataset contains 312 analogous variables recorded at 5-minute intervals by the wind farm’s SCADA, from 78 different sensors. Wind turbines consist of nine main systems, namely Converter, Generator, Nacelle, Rotor, Tower, Transformer, Transmission, Turbine, and Yaw. Some of these systems are further divided into specific subsystems.
Historical SCADA data collected from healthy wind turbines are used to model their normal behaviors and build a Mahalanobis space as a reference space. By comparing the predicted behavior of the wind turbine by a trained model with the reference space, anomalies can be detected.
To improve the reliability and optimize the maintenance strategy of a large-scale wind farm, a health condition assessment method of wind turbine generator system (WTGS) based on multiple turbines cooperation is presented in this paper.
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.
By comparing the predicted behavior of the wind turbine by a trained model with the reference space, anomalies can be detected. Finally, wind turbine faults are diagnosed through the analysis of the distributions and correlations of their SCADA data. The proposed approach is validated by using the SCADA data collected from two field wind turbines.
