REVERSIBLE ELECTRIC TURBO-EXPANDER PLANT Russian patent published in 2013 - IPC F25B11/04 F17D1/04 

FIELD: power engineering.

SUBSTANCE: reversible electric turbo-expander plant comprises an electric machine, a turbo-expander, an electric heater installed upstream and connected to an accumulator battery, installed as capable of recharging from an electric machine, an additional system of natural gas heating. It is equipped with a centrifugal supercharger and a gas turbine, kinematically connected with a turbo-expander, with a centrifugal supercharger and with an electric machine equipped with a semiconductor converter. The additional heating system is made in the form of a heat recuperator installed in the gas turbine, and connected via a water pump with a water heater, installed upstream the electric heater, and the accumulator battery is connected with the electric machine via a semiconductor converter. The electric machine is made in the form of a synchronous electric motor as capable of its operation in the mode of an electric energy generator or in the mode of a controlled electric motor.

EFFECT: expansion of device capabilities and increased operational reliability.
