FIELD: oil and gas industry.
SUBSTANCE: invention relates to devices for controlling pressure in gas line by means of expanders and can be used at gas distribution stations for electric power generation. Device includes gas distributor, a controller, a pressure sensor, turbine expander, electric generator, rectifier, inverter, load pickup external electric network, heating elements, power switches, load pickup heating elements, controlled power amplifier, an adder, scaling amplifiers, comparator, setter of nominal operating mode of turbine expander.
EFFECT: higher reliability by provision of permanent parameters of operating mode of turbine expander and smooth variation of gas flow passing through the turbine expander at significant load drops in electrical network.
