Method and installation for producing supplementary electrical energy

摘要

An installation for producing supplementary electrical energy for an electricity network includes at least first and second water reservoirs, the first water reservoir being situated at a first level and the second water reservoir being situated at a second level lower than the first level, a communicating pipe between the first water reservoir and the second water reservoir being provided with a remote-controlled valve, and a hydro-electric generating system being provided with a pumping installation. The first and/or second water reservoir is integrated in the foundations in the lower portion of an artificial building that needs to be built for a primary function independently of a secondary function of producing electricity. The first water reservoir or the second water reservoir may constitute a common body of water in the vicinity of ground level. The water reservoirs integrated in foundations of buildings may in particular cooperate with installations for air-conditioning or heating the buildings at the base of which they are constructed, or associated buildings.

1. An installation for producing supplementary electrical energy for an electricity network, comprising:
at least first and second water reservoirs, the first water reservoir being situated at a first level and the second water reservoir being situated at a second level lower than the first level with a level difference of at least 5 meters; at least one communicating pipe between the first water reservoir and the second water reservoir having a slope of at least 3% and being provided with at least one remote-controlled valve; a hydro-electric generating system; a pumping installation; and a control circuit, wherein at least one of said first and second water reservoirs comprises one or more individual reservoirs that are integrated in underground or semi-underground manner in the foundations of artificial buildings that need to be built for a primary function of sheltering goods or people independently of a secondary function of producing electricity, said water reservoir integrated in underground or semi-underground manner in the foundations of artificial buildings has a cumulative volume in the range 1000 m3 to 150,000 m3, said water reservoir integrated in underground or semi-underground manner in the foundations of artificial buildings includes at least one individual reservoir also connected to a natural cooling, sprinkler, cleaning, or firefighting installation, the other one of said first and second water reservoirs is likewise situated at ground level using a natural slope of the ground, and the hydro-electric generating system has a power rating in the range 100 kW to 4 MW.
