ABSTRACT:
Prior starting/generating systems which operate a generator as a motor to start a prime mover have been inefficient since motive power was delivered to the prime mover through hydrostatic trim and differential components of a constant speed drive interposed between the prime mover and the generator. In order to overcome this problem, means are provided between the prime mover and the generator for bypassing these components of the constant speed drive when operating in a starting mode so that motive power is transferred directly to the prime mover. This, coupled with the fact that the generator is operated as a motor responsive to generator speed and/or generator power factor, increases the efficiency of the system when in the starting mode.
