An electrical distribution system e.g. in an aircraft has parallel connected generators (GEN1, GEN2) powered by variable speed engines (ENG1, ENG2) Loads connected with each generator are interconnected through an electrical distribution bus 17. Constant speed drives (CSD1 CSD2) are driven by the engines and their outputs are directly connected with the generators, i.e. without the overrunning clutches used in some prior systems. An electrical protective circuit senses a flow of electrical power from the distribution bus to a generator, driving the generator as a motor. If the power flow to the generator is excessive, the bus tie breaker is opened disconnecting the generator from the bus. <IMAGE> |
