TL;DR: In this article, a combination of the optimization method of maximum likelihood estimator (MLE) and Newton Raphson (NR) resolution for identifying unknown parameters of single diode PV module at different test conditions is proposed.
Journal ArticleDOI
Prediction of Mechanical Shaft Failures Due to Pulsating Torques of Variable-Frequency Drives
TL;DR: In this paper, the effects of mechanical damping on the motor air-gap torque have been analyzed and the effect of variable frequency drive incorporated in a rotating shaft is shown to be one of the main root causes of mechanical shaft failures.
Proceedings ArticleDOI
A review of concepts and methods for wind turbines condition monitoring
TL;DR: This paper is a general review and classification of methods and techniques for wind turbine condition monitoring, and outlines the relationship between these theories and related technical concepts.
Journal ArticleDOI
Pulsating Torques in PWM Multi-Megawatt Drives for Torsional Analysis of Large Shafts
TL;DR: In this paper, the authors present new, simple, and linear mathematical relationships to predict pulsating torque frequencies in industrial multi-megawatt pulse width-modulated (PWM) drives.
