Distributed Air-Gap Flux and Rotor-Current Fusion for Operating-Regime Identification in a 10-MW Kaplan Hydrogenerator
Eduardo Jr Piedad, Rafel Roig, Xavier Escaler +2
Reliable monitoring of hydroelectric generators requires descriptors that capture both electrical loading and electromagnetic field behavior. This work investigates operating-regim…
Early Anomaly-Onset Detection based on Wigner--Ville Distribution Slice Spectra: A Transmission-Grid Test Case
Eduardo Jr Piedad, Eduardo Prieto-Araujo, Oriol Gomis-Bellmunt
Operational disturbance monitoring in power networks requires decisions to be made from waveform windows as they arrive, rather than from completed records after the event. This st…
Deep Learning-based Machine Condition Diagnosis using Short-time Fourier Transformation Variants
Eduardo Jr Piedad, Zherish Galvin Mayordo, Eduardo Prieto-Araujo +1
In motor condition diagnosis, electrical current signature serves as an alternative feature to vibration-based sensor data, which is a more expensive and invasive method. Machine l…
Exploring Wavelet Transformations for Deep Learning-based Machine Condition Diagnosis
Eduardo Jr Piedad, Christian Ainsley Del Rosario, Eduardo Prieto-Araujo +1
Deep learning (DL) strategies have recently been utilized to diagnose motor faults by simply analyzing motor phase current signals, offering a less costly and non-intrusive alterna…
