Problems solved by technology

For example, one of the generators in a parallel system may operate under relatively more severe conditions than one or more of the other generators and thus suffer relatively greater cumulative damage, whereby it is relatively easier to operate in the system failure in process
Continued business-as-usual reliance on generators with a relatively high pr

Example Embodiment

[0030] The embodiments of the invention described below are not intended to be exhaustive or to limit the invention to the precise forms disclosed in the following detailed description. Rather, the embodiments were chosen and described in order to enable those skilled in the art to appreciate and understand the principles and practice of the invention.

[0031] figure 1 An example parallel generator system embodiment connected to an electrical load is schematically shown. The depicted system 20 includes a main controller 22, and four generator units 24 connected in parallel, labeled G1, G2, G3, and G4, each having its own generator controller 26 . As discussed further below, the inclusion of main controller 22 is optional; generator controller(s) 26 of one generator unit 24 or of multiple generator units 24 may be adapted to perform the loads disclosed herein Share balance method. The generator units 24 may generally be driven by a single prime mover, or each may be driven...
