ABSTRACT:
A system (30) for providing electrical-power to remote communities (34) widely distributed over an extended geographical area (38) includes a generating station (32) located proximate each of the communities, each generating station supplying only that community to which it is proximate. The generating stations are in electronic communication with a central computer (40). Each generating station includes a plurality of generators (54-56). Each of the generators is controlled by a microprocessor based controller (64). Each controller is arranged to operate the generating station cooperatively with the other controllers associated with other generators in the station, and to assume a supervisory role in doing so by a mutual arbitration procedure among the controllers. Each controller is also arranged to monitor important generator operating parameters and to communicate these parameters to the central computer. Any controller may be reprogrammed by instructions communicated from the central computer, and functions of any controller may be overridden by instructions communicated from the central computer. The controllers include novel signal processing circuits (90 and 85) and logic for improved voltage and frequency regulation. The controllers also include novel circuits (92) and logic for monitoring generator fuel consumption and calculating generator fuel-efficiency therefrom.
