(54) ENERGY COMPLEX

one

The invention relates to the production of electrical energy and can be used in a power system for covering peak loads and leveling daily schedules of a power system, as well as for performing backup functions.

Known power complex, including thermal (nuclear) and pumped storage power plants. During peak hours, dropping water from the upper pool to the lower one, the pumped storage unit: the station produces electrical energy, and in the hours of load reduction, the pumped power station consumes the energy generated by the thermal (atomic) power plant and pumps the water from the lower pool to the upper one.

The disadvantage of this energy complex is the large losses in the conversion and transformation of energy during the operation of the pumped storage power plant.

. The energy complex is also known, including a pumped-storage power plant located on the same site and connected to a unified power system, containing an upper basin, pressure conduits, a building with hydro-power equipment, a lower basin, built in the form of underground schtololen, and a thermal (nuclear) power station with a steam generator. The electric generator, when operating in the pump mode, receives electricity from the thermal (atomic) electric station 2.

A disadvantage of the known energy complex is the large losses in the conversion and transformation of energy during the operation of hydroaccumulative j. power plants in the pump mode.

The purpose of the invention is to increase the efficiency of the energy complex during the operation of the pumped-storage power plant in the pump mode by reducing the losses for conversion and trans2 ° energy formation.
