Abstract

Regression-based Machine Learning (ML) approaches are mainly applied to fit the power curve for the performance evaluation of wind turbines (WTs). Although a fitted power curve is prevalent and straightforward for anomaly detection, it is difficult to identify the fault types at the rotor side of a WT, particularly, because the operation can be dependent on multiple parameters. The present paper suggests an interesting approach towards condition monitoring (CM) and fault diagnosis of a DFIG by only processing rotor currents through several signal processing techniques to recognize and localize miscellaneous electrical disturbances. A non-parametric regression approach, Gaussian process regression (GPR), is advised to fit the no-fault performance curve (PC) of rotor current standard deviation (SD) versus wind speed. Thereafter, a hybrid approach with GPR is investigated to visualize no-fault operation, yield the anomaly, and conduct fault recognition at the rotor side with outstanding validation scores in terms of accuracy, dependability, and security.
