Research on fatigue damage detection for wind turbine blade based on high-spatial-resolution DPP-BOTDA In this paper, a fatigue damage detection system used for wind turbine blade is successfully developed by using highspatial- resolution differential pulse-... J Xu,Y Dong,L Hui - International ...
Therefore, amplitude data is selected as the condition monitoring data and fault data for the wind power gearbox. This paper utilizes the actual fault monitoring data from a wind farm unit’s gearbox for simulation. The specified service life for this type of wind turbine is 15 years, with ...
To address the issues of low accuracy and high false positive rate in traditional Otsu algorithm for defect detection on infrared images of wind turbine blades (WTB), this paper proposes a technique that combines morphological image enhancement with an improved Otsu algorithm. First, mathematical ...
The two parameters of the thickness of the ball table plate and the thickness of the ball table wall are researched in the paper. In order to explore the influence of the inclusion, the web member and the thickness of tower column on the joint, the thickness of the ball table plate is ...
A prioritized list is developed for wind turbine aerodynamic research needs and opportunities which could be used by the Department of Energy program management team in detailing the DOE Five-Year Wind Turbine Research Plan. The focus of the Assessment was the basic science of aerodynamics as applie...
Berry is co-author of a new paper titled, “Structural Comparison of a Thermoplastic Composite Wind Turbine Blade and a Thermoset Composite Wind Turbine Blade,” which appears in the journal Renewable Energy. The other authors, also from NREL, ar...
This paper describes a computer method to allow the design of small wind turbine blades for the multiple objectives of rapid starting, efficient power extraction, low noise, and minimal mass. For the sake of brevity, only the first two and the last objec
Analyzing the wind turbine with a direct-driven PMSG, this paper proposes a low voltage ride through scheme of PMSG wind power systems based on feedback linearization. The DC-Link voltage is controlled by the generator-side converter rather than the grid-side converter. Considering the nonlinear ...
In order to reflect the superiority of the method proposed in this paper in recognition accuracy, we compare the total recognition accuracy of the method proposed in this paper with that of literature 35, 36 and 37 on the test set. The comparison results are shown in Fig. 10. The ...
