A given three-phase 2 pole 50 Hz, 1000 KVA, 4.8kW star connected synchronous generator has a reactance of 40Ω/phase. Assuming the machine operates at rated kVA with a power factor of 0.85 lagging. Calculate
i) the excitation voltage
ii) power angle

For this question, how do I start? What does 2 pole mean and how does it affect the calculations?
