FIELD: electricity.
SUBSTANCE: in case of excess of eclectic energy supply over its demand electric energy is diverted through a heating element directly to the thermal accumulator and in case of this accumulator discharge the heat from the accumulator is collected and by heat-exchange process is introduced to thermodynamic cyclic process indirectly. At that electric energy is generated. Heat of the thermal accumulator is sent to the power-generating plant and used for air heating in the combustion chamber air duct of the power-generating plant or fuel for the combustion chamber in the power-generating plant is heated by heat of the gas turbine thermal accumulator.
EFFECT: reducing fuel consumption and increasing the total efficiency factor for the power-generating plant.
