ANALYSIS OF A HYDRO GENERATOR THERMAL REGIMES
The paper analyses the thermal regimes of a vertical synchronous hydro
generator, coupled with a Kaplan hydraulic turbine, depending on its active and
reactive powers. Operation at temperatures higher than permissible limits leads
to defects and abnormal functioning of hydro generator. The optimal
temperature increases stability and extends the lifetime of hydro generator, by
slowing aging of the rotor and stator windings.
