Microstructural changes in White Etching Cracks (WECs) and their relationship with those in Dark Etching Region (DER) and White Etching Bands (WEBs) due to Rolling Contact Fatigue (RCF)

International Journal of Fatigue, 2017
Substantial microstructural changes, such as Dark Etching Region (DER), White Etching Bands (WEBs) and White Etching Cracks (WECs), can occur in typical bearing steels such as AISI 52100 and 4320 due to Rolling Contact Fatigue (RCF). Although it has been

Second-order sliding mode voltage-regulator for improving MPPT efficiency of PMSG-based WECS

, 2020
Driven by the rapidly growing use of wind power, the maximum power extraction of wind energy conversion systems (WECS) has become a significant issue. However, due to the stochastic nature of the wind, employing a nonlinear controller to provide a good ...

ANN Approach to WECS Power Forecast

2005 IEEE Conference on Emerging Technologies and Factory Automation, 2006
In this work-in-progress the problem with the future integration of large quantity of wind generators in the Portuguese electric grid is presented. A method based in artificial neural networks (ANN) is used to predict the average hourly wind speed. The work starts by choosing the patterns set length, the ANN structure and the learning method.
