GUARANTEED POWER SUPPLY DEVICE Russian patent published in 2013 - IPC H02J9/04 

FIELD: electricity.

SUBSTANCE: device comprises a reserve diesel generator, a decoupling unit with a power system, comprising a rectifier connected in series through DC buses with an inverter and a source of uninterrupted power supply connected to a DC bus or an accumulator battery, circuit breakers for connection of an autonomous power station, an accumulator battery and a diesel generator to an AC bus, facilities for automatic disconnection of loads supplied from an AC bus, a control system connected to a gas piston power station, a diesel generator and a source of uninterrupted power supply; a gas piston autonomous power station is connected to the AC bus via a decoupling unit with a power system. The device is equipped with thyristor devices of automatic load transfer, one of which is connected in parallel to the circuit breaker for connection of the autonomous power station to the AC bus, and another one - in parallel to the circuit breaker for connection of a diesel generator to the AC bus, and a thyristor switch connected in parallel to the circuit breaker for connection of the accumulator battery to the AC bus, outlets of the control system are connected to inlets of the thyristor devices of automatic load transfer and the thyristor switch.

EFFECT: power supply reliability improvement.
