1. A power-generating system comprising:

  • a plurality of engine driven electrical generators each having a field winding;

    a common busline;

    a plurality of actuatable switching means each for, upon actuation, electrically connecting a corresponding one of said plurality of generators to said common bus line;

    means for substantially simultaneously actuating each of said plurality of actuatable switching means so that each of said plurality of generators are substantially simultaneously connected to said common busline;

    a plurality of engines each coupled to a corresponding one of said plurality of generators to thereby drive the corresponding one of said plurality of generators;

    means for substantially simultaneously starting each of said plurality of engines to thereby substantially simultaneously apply motive power to each of said plurality of generators;

    a plurality of first actuatable circuit means each having a first position for coupling a corresponding generator field winding to a source of excitation and a second position for decoupling a corresponding field winding from a said source of excitation;

    a plurality voltage regulator means each for monitoring the value of a signal developed by a corresponding generator and including circuit means for developing an output signal having a value representative of a said monitored signal, each said voltage regulator circuit means being coupled to a corresponding generator field winding; and

    , second actuatable circuit means for, upon actuation, coupling said common busline to said voltage supply line to thereby energize said voltage supply line.
