US Patent 7521902 Power balancing of multiple synchronized generators

Power balancing techniques for a synchronous power generation system are provided. One exemplary method for balancing power in a synchronous generator system includes determining an output power characteristic of a synchronous generator driven by a prime mover and comparing the characteristic to a value derived from the output power of a plurality of synchronous generators. The method also includes providing a correction signal to the synchronous generator to modify the output power produced by that generator. A synchronous power generation system having a plurality of synchronous generators driven by a common prime mover is also provided.
