SYSTEM FOR AUTONOMOUS POWER SUPPLY OF THE COMPRESSOR STATION OF THE MAIN GAS PIPELINE WITH SIMULTANEOUS HYDROGEN PRODUCTION AND THE POSSIBILITY OF MIXING IT INTO THE PUMPED GAS Russian patent published in 2022 - IPC F04D25/00 F02C6/00 

FIELD: energy systems.

SUBSTANCE: invention relates to energy systems and complexes and is a device for organizing an autonomous power supply of a compressor station of a main gas pipeline with simultaneous production of hydrogen during periods of failure in the load of electric gas compressor units and mixing the generated hydrogen into the gas pumped through the main gas pipeline, as well as the possibility of using the accumulated hydrogen as a fuel for temporary backup power supply of the compressor station itself. To achieve the effect, an autonomous power supply system is proposed for the main gas pipeline compressor station, containing a power generation device connected by a conductive line to an electric power distributor, which is connected in parallel by conductive lines to two electric transformers, one of which is connected in series to a power supply switch, an electric gas compressor unit installed on the main gas pipeline, the other - with an electrolysis plant for the production of hydrogen, connected by pipelines through a water treatment system to a water source, separate gas pipelines with a hydrogen compressor and an oxygen compressor, which are connected to the storage tanks for hydrogen and oxygen, respectively, while the electrolysis plant contains a separate oxygen discharge pipeline, storage tanks for hydrogen and oxygen are connected to an electrochemical generator or a gas turbine unit for power generation, connected by a pipeline to the water treatment system, and by a current-carrying line through an electric generator with a power switch, the hydrogen storage tank is connected by a gas pipeline to a hydrogen injector located on the main gas pipeline.

EFFECT: creation of a power supply system for a compressor station located without the ability to connect to the power grid of the required capacity, including: a system for the production and distribution of electricity, a system for the production and storage of hydrogen and oxygen, an injector for mixing hydrogen into the main gas and, in fact, obtaining a mixture of natural gas at the outlet of the compressor station and hydrogen, a power plant for backup power supply of the compressor station, which generates electricity from the accumulated hydrogen and oxygen.
