OPTIMUM DISTRIBUTION SYSTEM OF ELECTRIC POWER GENERATED AT GAS REDUCTION AT GAS DISTRIBUTION STATION

摘要

FIELD: heat power engineering.;SUBSTANCE: invention relates to heat engineering, more specifically to production of electric energy, cold and liquefied natural gas at reduction of natural gas at gas distribution stations (GDS). System for optimum distribution of electric power generated during reduction of natural gas, is connected to gas distribution station, connected between main gas pipeline and consumer gas line, and includes one, but not limited to expander-generator, cold supply unit, control unit, natural gas liquefaction unit and drying unit. Input of expander-generator is connected to output of drying unit, and output of expander-generator is connected by pipelines of supply, removal of natural gas with consumer gas line, with units of liquefaction and cooling supply. Expander of expander-generator is connected by electric communication with unit of control controller, which in its turn is connected by electric communication with units of drying, liquefaction, cold supply and with electric consumers of gas-distributing station. Connection of control controller unit with functions of analysis of operation of all system units, power consumption, control, redirection of electric power flows, and establishment of electric connection with generator of expander generator allows maximum optimization of distribution of power flows generated by expander-generator at reduction of natural gas to GDS.;EFFECT: higher economic efficiency of GDS operation due to optimization of distribution of electric energy generated during reduction of natural gas to GDS.;1 cl, 1 dwg
