WELL PUMPED-STORAGE INSTALLATION Russian patent published in 2009 - IPC F03B13/06 F03B13/10 

FIELD: engines and pumps.

SUBSTANCE: invention relates to energetics, particularly to devices for receiving of electricity excluding burning of fuel for it and is a renewable energy source. Operation of power plant includes two processes: energy generation (EG) and water lifting (WL), do not matching in time, herewith WL is implemented ensured by electric power generated by wind-driven powerplant 19 (WDP). EG is implemented by hydraulic unit including hydraulic machine 5 in the form of hydroturbine, connected to electric machine 6 in the form of electric generator, installed in drill hole, in which operates hydropower water flow (HWF), hydraulic power of which transforms by hydraulic unit into electric energy and passed to original ground. HWF is formed by water flow from located higher water source 2, communicated to drilling well 1, and area of water withdrawal is communicated to it drainage area, located lower the water source. Drainage area can be underground collector, cavitated formation, absorption area 16, 17 or 18 and others, its volume is limited. Hydroturbine, electric generator and current communications channel 9 of downhole hydraulic unit with electrical switching transforming panel 11 at original ground are adapted for operation in downhole conditions. WL provides three versions of water lifting from absorbing area: borehole hydraulic unit is reversible hydraulic machine herewith hydraulic machine is implemented in the form of centrifugal pump, and electric machine in the form of electric motor, and for lifting of water it is used the sane drill well 1, for water lifting it is used special production well 24, by which it is over-drilled absorbing area and in which it is installed water-lifting pipe string 26 with perforated section 27 with submersible pump at its bottom end, for water lifting there are used pumping wells 34 and 35, drilled up to absorbing areas 17 and 18 and water-lifting wells 53 and 54, by which there are over-drilled absorbing areas 17 and 18.

EFFECT: creation of nuclear power plant, allowing wide range of application conditions.
