HYBRID POWER COMPLEX Russian patent published in 2025 - IPC F03D9/00 H02S10/12 F03D7/00 H02J7/34 

FIELD: renewable energy.

SUBSTANCE: invention relates to renewable power engineering, in particular to hybrid power complexes, and is intended for uninterrupted power, heat and cold supply of local facilities. Hybrid power system comprises a drive diesel engine start-up machine, comprising a voltage meter, a DC amplifier and a relay with normally open contacts, an axial frequency converter, output of which is made with possibility of connection to local AC network, second and third rectifiers, differential-minimum relay. Relay contains a polarized relay with normally open contacts and a contactor with normally closed and normally open contacts made with possibility of connection to the accumulator battery through normally open contacts of the polarized relay. Output of the vertical-axial three-input axial generator set is connected to the first input of the polarized relay of the differential-minimum relay through the second rectifier and is configured to be connected to the input of the axial frequency converter through the normally closed contacts of the contactor of the differential-minimum relay. Output of the axial multiphase contactless synchronous generator is connected to the second input of the polarized relay of the differential-minimum relay through the third rectifier and is configured to be connected to the input of the axial frequency converter through the normally open contacts of the contactor of the differential-minimum relay. Input of voltage meter is connected to output of vertical-axial three-input axial generator set, and its output is connected to input of DC amplifier of automatic starter of drive diesel engine, to output of which relay winding is connected. Starter of drive diesel engine is made with possibility of automatic connection to accumulator battery through closed normally-open contacts of relay.

EFFECT: providing automatic connection of consumers to a standby power supply source, stabilizing the output voltage of the hybrid power complex in terms of value and frequency.
