    Please give me solution to this question

    3 shunt generators each having armature resistance of 0.1 are connected across common bus feeding a 2 ohms load.there generated voltages are 127,120,119.neglecting filed currents.calculate bus voltages and modes of operation of 3 machines?

    3 shunt generators each having armature resistance of 0.1 are connected across common bus.

    Bus voltage is 120 V.

    Generator with highest internal emf i.e., 127V acts as generator.

    Generators with next higher internal emf i.e., 120V neither draws nor supply any current.


    Generators with lowest internal emf i.e., 119V acts as synchronous generator.
