Thermal Intelligence for Hydro-Generators: Data-Driven Prediction of Stator Winding Temperature Under Real Operating Conditions

Energies
Hydropower remains one of the primary sources of power generation. It can be operated as either a base-load or peak-load plant due to its rapid, easy start-up and stop-down capability. However, power plants, old or new, need to be operated and maintained
