Answer / jaru

for the generation of elect power we need a prime mover
which supplies mechanical power input to the alternator, can
be steam turbines ,or hydroturbines.when poles of the rotor
moves under the armature conductors which r placed on the
stator ,field flux cut the armature conductor,therefore
voltage is generated.and is of sinusoidal in nature...due to
polarity change of rotor poles that is N-S-N-S..

What are various power system instabilities and what are their effects on power system operation?
