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.

[ What is claimed is:] [1.] In a control system for an electrical power generator, the control system including a microprocessor and circuit elements driven by the microprocessor for maintaining generator output voltage at a preset level based on a measurement of the generator output voltage, an electrical circuit for providing the microprocessor with signals representative of the measurement comprising:means for receiving a generally sinusoidal, positive and negative going, first analog signal representative of the output voltage of the generator;means for converting said first analog signal into a second analog signal having only positive going cycles, alternate ones of which are representative of the magnitude of alternate positive and negative half-cycles of said first analog signal;means for converting said first analog signal into a square-wave pulse representative of polarity of said alternate half-cycles of said first analog signal; andwherein said square-wave pulse and said second analog signal are provided to the microprocessor for controlling the output voltage of the generator.
