what is the difference between the alternator used in hydro and thermal power plants??
Answer Posted / gopal manda
in hydro power we use salient pole type alternetor are use
because hydro turbine(Prime mover of alternator)is rotating
at 750 RPM.so it can't possible to manufacture/make 6 pole
on cylendrical rotor to maintain the power frequency.and in
thermal power plant steam tubine rotate at 3000 rpm so we
construct 2pole on its rotor/field winding for maintain the
frequency.so we use cylendrical rotor are use
