FIELD: measuring equipment.
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 comprises a gas distribution device, a controller, pressure sensors, a turboexpander, an inverter, load cell, heating elements, power switches, scaling amplifiers, adders, flowmeter, comparison units, corrector and setpoint regulator of the turboexpander, corrector and minimum value loader for heating elements, differential pressure calculation unit, gas reserve energy calculation unit, comparators, signaling and disconnection units for the maximum value of the external load.
EFFECT: technical result is an increase in the reliability of the device operation by maintaining the required amount of natural gas heating depending on its consumption and matching the stored energy of compressed gas and electric power back-to-back.
