Distributed Air-Gap Flux and Rotor-Current Fusion for Operating-Regime Identification in a 10-MW Kaplan Hydrogenerator
arXiv:2606.27800v1 Announce Type: cross Abstract: Reliable monitoring of hydroelectric generators requires descriptors that capture both electrical loading and electromagnetic field behavior. This work investigates operating-regime identification in the Porjus U9 10-MW Kaplan hydrogenerator using synchronized measurements from ten stator-mounted Hall probes and six rotor-current channels. Seven steady guide-vane-opening settings are considered, and each 300s record is divided into 1s windows. The resulting windows are represented by spatial Fourier descriptors of the circumferential air-gap fi
The paper leverages advanced sensing and AI techniques to improve monitoring of critical infrastructure like hydrogenerators, indicating a broader trend towards predictive maintenance and asset optimization across industrial sectors.
Reliable and efficient operation of large-scale power generators, especially renewable ones like hydro, is crucial for grid stability and energy security, directly impacting the energy bottleneck narrative.
The application of distributed Hall probes and rotor-current fusion enables more precise and real-time identification of operating regimes, potentially reducing downtime and extending the lifespan of critical energy assets.
