60 Hz 24-pole 3phSM, Xd = 1.2 Ohm. Determine the machine speed.
For operation at rated conditions, evaluate all stator phasors
and draw the phasor diagram for operation in the following
modes generator; pf = 0.866 lagging generator; pf = 0.866
leading motor; pf= 0.866 lagging motor; pf = 0.866 leading For
each mode in (a), determine the direction of P and Q flow (into
or out of the 3phSM) The 3phSM is used in a pumped storage
application which has a head of 250 m. When pumping or
generating, it operates at 84% efficiency, rated stator
conditions. Determine the turbine flow when (1) generating and
(2) pumping.  Answers (0)
