FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used for preventive control of ship electric power systems. Disclosed is a device for preventive protection of a ship electric power system against overloads, which contains the following by the number of generator units (GU): GU load sensors, threshold units, the first NAND logic elements, AND logic elements, univibrators, as well as a load equality control unit and the second NAND logic element.
EFFECT: simplification of the device due to exclusion of the load distribution unit, which provides the possibility of automatic change of the dead zone of three-position regulators.
