A 100 hp, 440 V, 0.8 PF (leading), synchronous motor has an armature resistance of 0.222 and a synchronous reactance of 3.0 22. (a) If EA = 430 2 13.5° V and VT = 440 2 0° V. is this machine consuming real power from or supplying real power to the power system? Is it consuming reactive power from or supplying reactive power to the power system? (b) Calculate the real power P and reactive power Q supplied or consumed by the machine under the conditions in part (a). Is the machine operating within its ratings under these circumstances? (c) If Ea = 470 212° V and V1 = 440 20° V, is this machine consuming real power from or supplying real power to the power system? Is it consuming reactive power from or supplying reactive power to the power system? (d) Calculate the real power P and reactive power Q supplied or consumed by the machine under the conditions in part (c). Is the machine operating within its ratings under these circumstances?
