A long-shunt, cumulatively compounded dc generator has 1800 shunt-field turns per pole and 12 series-field turns per pole. The armature resistance is 0.12 ohm, the series-field resistance is 0.04 ohm, and the shunt-field resistance is 210 ohms Data for the open-circuit characteristic at 1700 r/min is as follows: Volts 110 200 280 300 Amperes 0.5 1.9 2.35 The generator supplies a load of 15 kW at 200 V when it is driven at 1700 r/min. Determine the speed at which the generator must be driven to supply a load of 23 kW at 270 V. Assume armature reaction is proportional to the armature current squared
