Answer Posted / sethar12
The problem is not that the frequency of the generator is
decreasing, but the problem is that when this frequency
decreases upto the underfrequency limit of the turbine (or
generator)(frequency bandwidths as given by manufacturer)
(generally at 48Hz). It must be noted that the turbine (or
generator) can run for some commutative duration in
different frequency bandwidths even below 48Hz, but it is
better to avoid in these bandwidths because turbine blades
may damage due to resonance.
The most effective solution is the load-shedding
(distribution side) (by asking the transmission network
controller).
Otherwise reducing the generator load manually.
