The synchronous reactance of a three-phase, star connected, 380 V, 50 Hz, cylindrical alternator with 2 poles is Xs = 1.5 Ω/ phase. This alternator is connected to an infinite bus. As the alternator powers the bus with 100 kW, the angle between the induced voltage and the terminal voltage is δ= 25,09 °. Find the following for this alternator with neglected losses. A) The torque applied to the shaft of the alternator b) The induced voltage in the alternator c) The active and reactive components of the apparent power AND The power coefficient AND The rotation speed of the alternator.
