A An Aircraft Carrier Has A 3 Phase Y Connected 2 Pole 60hz Synchronous Generator Rated To Deliver 1000kva At A Fp 1 (416.16 KiB) Viewed 31 times

a. An aircraft carrier has a 3-phase, Y-connected, 2-pole, 60Hz synchronous generator rated to deliver 1000kVA at a Fp = 0.8 lagging with a line voltage of 100v. The resistance of the armature is 0.0042, while the reactance 0.50. However, the actual load on the generator draws 500kW at Fp=0.65 lagging. Assume that a voltage regulator has automatically adjusted the field current so that the terminal voltage is its rated value. Mechanical losses are 100kW under rated conditions. Determine the reactive and apparent power delivered by the generator under rated conditions. (Ans: P = 800kW; Q = 600kVAR) b. Find the current delivered by the generator under rated conditions. (Ans: I Line = 5.77kA) What is the overall efficiency under rated conditions? (Ans: n = 61.5%) d. What is the speed of the prime mover in rad/sec under roted conditions? (Ans: w = 377 rad/sec) Fill out the power conversion diagram for this Ad generator when under roted conditions, C. e.
