Generator is normally feeds power to the infinte grid which
is having a number of generators connected.
If by some reson turbine gets tripped but if GCB not get
opened in that case there will be a reverse flow of power
from grid to stator wdg and the generator will behave as a
induction motor. In this case there will be a heating of
rotor end ring and and outer wedges of the same which will
in turn damage the rotor winding. To avoid this reverse
power flow is resricted by tripping the generator on
reverse power flow.
