Three de shunt generators in parallel running each having an armature resistance of 0.2ohms. running at the same speed and excited to give equal share of total load of 200 kW at a terminal voltage of 500V into a load of fixed machine. If the field current of one generator is raised by 2%, the other remaining unchanged, calculate the output power of each machine and their terminal voltage under this conditions. Assume the speed remains constant and the flux is proportional to field current.
