A 480-V, 60-Hz, A-connected, four-pole synchronous generator. This generator has an armature resistance of 0.01512 and a synchronous reactance of 0.132. Armature rms induced voltage (Eg) equal to 532 V and the torque angle is 5.3° at a terminal voltage of 480 V. Ignore any field circuit losses. Find: please write understandable and step by step. 1) Speed of rotation. 2) Magnitude of load current (line). 3) Load power factor and determine whetker it is lagging or leading. 4) Output power of the generator 5) Air gap power of the generator. 6) Find the air gap torque. 7) If the generator's efficiency is 89.7%, find friction and iron losses? 8) Find the input torque. 9) Suppose a new load drawing a line current of 1200 A at unity PF is connected to the generator. Find the required excitation voltage (Eg) to keep terminal voltage at 480 V? What is the voltage regulation? 10) Suppose a new load drawing a line current of 1200 A at 0.8 PF leading is connected to the generator. Find the required excitation voltage (Eg) to keep terminal voltage at 480 V? What is the voltage regulation?
