1. In a generating system driven by a source of motive power for energizing a load, including means for developing main generator field current, a rotating main generator field winding coupled to the developing means and to the source of motive power for generating a moving main generator magnetic field and a stationary main generator armature disposed in the moving main generator magnetic field for generating main generator output current, the improvement comprising:

  • means for sensing the voltage at the load;

    means coupled to the load voltage sensing means for detecting when the load voltage is less than a predetermined value;

    means for sensing the voltage at the main generator armature; and

    means responsive to the detecting means and coupled to the developing means and the armature voltage sensing means for controlling the main generator field current in response to the sensed voltage at the main generator armature when the sensed voltage at the load is less than the predetermined value.
