Patent ID: 7122916

Claim:
A multi-unit power generation system comprising: a plurality of generators, each generator connected in parallel, wherein at least one generator comprises a microturbine generator connected to a corresponding output isolation transformer to convert a generator output voltage to a site operating voltage; a switching system for switching between and/or aggregating a generator load produced by the plurality of generators and a utility grid load; and a control system in communication with each said generator for communicating command signals to each said generator and in communication with said switching system for commanding the switching system to switch between or aggregate the generator load and the utility grid load, wherein the control system designates a first generator as a master generator and all other generators as slave generators, and wherein the master generator produces and transmits a synchronization signal indicating an operating frequency to the slave generators, and wherein during power failure in the master generator, the master generator continues to communicate a synchronization signal indicating said frequency to the slave generators.
