Wind Turbine Gearbox Anomaly Detection Based on Adaptive Threshold and Twin Support Vector Machines

IEEE transactions on energy conversion, 2021
Data-driven condition monitoring reduces downtime of wind turbines and increases reliability. Wind turbine operation and maintenance (O&M) cost is a significant factor that calls for automated fault detection systems in wind turbines. In this manuscript,

Condition Monitoring of Wind Turbine Generators Using SCADA Data Analysis

IEEE Transactions on Sustainable Energy, 2021
Utility-scale wind turbines are equipped with a supervisory control and data acquisition (SCADA) system for remote supervision and control. The SCADA system accumulates a large amount of data that contains the health conditions of the wind turbines. Thus,

Fault Diagnosis of Wind Turbine Gearbox Using a Novel Method of Fast Deep Graph Convolutional Networks

IEEE Transactions on Instrumentation and Measurement, 2021
The fault diagnosis of the gearbox of wind turbines is a crucial task for wind turbine operation and maintenance. Although a convolutional neural network can extract the related information of adjacent sampling points using kernels, traditional deep ...

Pneumatization of Turbinates

The Laryngoscope, 2003
AbstractObjectives To present unusual computed tomography (CT) findings concerning huge pneumatization of turbinates and paranasal sinuses in one patient. In current world literature the authors only found nine reports of pneumatization of inferior turbinates, which, therefore, must be considered an extremely rare anatomical finding.Study Design Case ...

ON THE COOLING OF GAS TURBINES

Journal of Flow Visualization and Image Processing, 2001
This article deals with measurements of convective heat transfer coefficients in three fluid flow patterns that concern both internal and external cooling of gas turbine components; in particular, the flow in a couple of smooth, or ribbed, ducts connected by a 180° sharp turn, a jet in cross-flow, and a jet impinging on a wall for short nozzle-to-wall ...
