Abstract
A control for an electrical generating and distribution system utilizing a plurality of interconnected microprocessors. An electrical system, for an aircraft for example, may have two engine driven generators and an auxiliary power unit generator with loads connected to each of the engine driven generators through generator circuit breakers. An electrical distribution bus connected through bus tie breakers interconnects the load circuits and the auxiliary generator so that any one generator can power either or both loads. Each generator has a microprocessor generator control unit responsive to the associated generator conditions to control generator operation. A microprocessor bus power control unit is responsive to distribution circuit conditions and correlates information from the generator control units, contributing to operation of the bus tie breakers, controlling distribution of power from the generators to the loads. Serial data links between the bus power control unit and each of the generator control units provide for communication of input and control information and enable comparison of redundant circuit information enhancing reliability of the system operation.
