working on a problem which asks for the maximum output of a sync gen.
given 3-phase, rated for 15kv, 10mva, 0.78pf lag, sync reactance of 14 ohms per-phase and internal voltage of 14.92 at an angle of 14 degrees.
answer says max output occurs when torque angle (angle between internal voltage and phase voltage) is 90 degrees.
Pmax = 3 * 15kv/sqrt(3) * 14.92angle14 degrees / 14 = 27.7MW
can anyone expand on this???
