Abstract:
A hydroelectric power plant comprising a plurality of windmills connected to compressed air generators to provide pressurized air to a set of liquid storage tanks, said compressed air generators each having an air dryer to dry the compressed air produced by the air generator, each storage tank having a high pressure liquid outlet, a liquid inlet and an air inlet and air outlet, the liquid outlet of each storage tank being connected to a liquid inlet of a turbine that generates electricity when liquid passes through the turbine, the turbine having a liquid outlet and an electrical power outlet, the liquid outlet of the turbine being connected to a recycle line that is in turn connected to the liquid inlets of the storage tanks, a high pressure air reserve system to store high pressure air for use when wind velocities are not sufficient to operate the plant, said air reserve system having an air inlet and an air outlet, control means connected to control the transfer and distribution of pressurized air to the storage tanks, to control the flow of high pressure air to and from said air reserve system, to control the flow of high pressure liquid from the storage tanks to the turbine, and to control the recycling of liquid from the liquid outlet of the turbine to the liquid inlets of the storage tanks, said electrical power outlet of the turbine being connected to a power line, said liquid being water or mainly water.
