5-11. A 500 kVA, 600 V, 0.8-PF-leading, Y-connected synchronous motor has a synchronous reactance of 1.0 per unit and an armature resistance of 0.1 per unit. At the current time, EA = 1.00 pu and pu.

(a) Is this machine currently acting as a motor or a generator?

(b) How much power P is this machine consuming from or supplying to the electrical system?

(c) How much reactive power Q is this machine consuming from or supplying to the electrical system?

(d) Is this machine operating within its rated limits?
