ELECTRIC GRAVITY ACCUMULATION STATION Russian patent published in 2025 - IPC F03G7/08 F03G3/00 F03G6/06 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric energy accumulation during the load drop in the power system and its output to the power system during the load increase period. Known electric gravitational accumulation station (EGAS), comprising a load located on a support surface, an electric machine, is equipped with toothed rails made with possibility of fixation on support surface, to the central section of which a current lead is connected, made in the form of a flexible hose cable with the possibility of being connected to the power system, wherein electrical machine is made in form of three-phase synchronous electrical machine (SEM), cargo is made in the form of a double-decker platform installed on toothed rail tracks by means of gear wheels-gears in the form of front guides and rear driving wheels and containing located on its first floor two horizontal three-stage reduction gears, SEM, a storage battery, rectifier, auxiliary transformer (AT), control cabinet (CC) with computer automation unit (CAU), thyristor exciter (TE), inverter, as well as solar panels located on the second floor of the station platform, wherein the rear drive wheels of the platform are connected to two cylindrical horizontal three-stage reduction gears, connected, in turn, to two working ends of the SEM shaft, rotor winding of three-phase synchronous electric machine is connected to storage battery, first input of storage battery is connected to solar panels, second input of storage battery is connected to output of rectifier, input of which is connected to first output of auxiliary transformer, auxiliary transformer input is connected to control cabinet first output, and second output of auxiliary transformer is connected to input of thyristor exciter, output of which is connected to first input of SEM, first output of storage battery is connected to input of inverter, second output of storage battery is connected to second input of SEM, which third input is connected to the first output of the inverter, the first input of the control cabinet is connected to the power system, CC second input is connected to the inverter second output, the CC second output is connected to the SEM fourth input, third output of CC is made with possibility of connection to autonomous consumer. Support surface can be inclined or vertical.

EFFECT: increased power efficiency and efficiency of the electric energy accumulation system with minimization of costs and area of land allotment, as well as reduced weight of the structure.
