DEVICE FOR OBTAINING ADDITIONAL ELECTRIC POWER FOR AUXILIARY NEEDS OF HYDROELECTRIC POWER PLANT AND METHOD OF OPERATION THEREOF Russian patent published in 2025 - IPC F03B13/00 E02B9/00 

FIELD: electricity.

SUBSTANCE: group of inventions relates to the field of hydropower engineering, in particular to devices for power generation, and can be used for power supply of hydroelectric power plants (HPP) due to use of service water energy of hydraulic units, including in emergency situations. Proposed device comprises process water supply system with drain pipeline 9 and water intake 1, filter 2, oil coolers 7 and air coolers 5. Device is equipped with bypass pipeline 11, spare bypass pipeline 16, gate valves 3, 10, 12, micro-hydroelectric power station consisting of hydraulic turbine 13 and generator 14. Pipeline 11 with gate valve 12 and micro-hydroelectric power station are embedded in pipeline 9 of service water supply system. Pipeline 16 with gate valve 15 is cut into the service water supply system after filter 2 and is connected to micro-hydroelectric power station to maintain water head from the headwater side in emergency cases.

EFFECT: group of inventions is aimed at use of energy potential of existing pressure hydroelectric systems, as well as provision of more rational use of water in system of process water supply, supplied for cooling of equipment of hydroelectric power stations.
