(c) (iv) A separately excited DC generator is rated at 172 kW, 430 V, 400 A and 1800 rpm. Its magnetization curve is shown in Figure Q4(c). The generator's characteristics are: RA= 0.05 RF = 2002 Radj = 0 to 300 (i) (iii) VF = 430 V NF = 1000 turns per pole Sketch an equivalent circuit of the generator with proper labels. If Radj = 63 N, and the prime mover is driving at 1500 rpm, calculate the generators' no-load terminal voltage. Calculate the terminal voltage if a 360 A load is connected to its terminal. Assuming the generator does not have compensating winding. Its armature reaction at this load is 450 A. turns. The prime mover is driving at 1500 rpm. For Q4(c)(iii), the terminal voltage is lower than no-load terminal voltage calculated from Q4(c)(ii). Investigate the adjustment of field current, IF and Radj to raise for the terminal voltage to match the no-load terminal voltage. |
