gen under freq is needed to protect the generator and the
load, -for generator because under overloading condition
the generator will slow down to try to accomodate the extra
load, this will result in overheating of stator windings,
while also under this condition (under freq) some equipment
can be damage or stall because of under freq. A load
shedding scheme using dedicated freq sensing relays will
trip (disconnect) a set of load from the grid to recover
from under freq and stabilize the system avoiding damage to
generator and connected equipments.
