| Summary: | For high power and high revolution aggregates it is required that the
operation should take place in safe conditions, for all the running regimes.
The most difficult regimes for a hydro aggregate are the transitory
regimes. Although, these regimes generally last a rather short period
of time, for high power aggregates these regimes are accompanied
by electric and mechanic solicitations which sometimes can surpass the
admitted values. In the present paper, we present an evaluation method
of the rotating parts’ dynamic stability of the hydro aggregates in
the transitory regime of putting off load. We present the results obtained
from the recordings of putting off load and those obtained after
the dynamic equilibration of the hydro aggregate’s rotor. |
