1. A method for paralleling a plurality of generators to a de-energized paralleling bus, the method comprising:
monitoring an output signal of a first generator of the plurality of generators;
identifying a property of the output signal of the first generator;
generating a digital synchronous message including timing data indicative of the property of the output signal;
sending the digital synchronous message to a second generator of the plurality of generators, wherein at least one generator characteristic of the second generator is adjusted in response to the synchronous message; and
determining a connection time for simultaneously connecting the first generator and the second generator to the de-energized paralleling bus based, at least in part, on the timing data.
