Abstract

A wind-driven rotor drives a pump 3, which pumps liquid from a low pressure storage tank 9, into a gas-pressurised storage tank 5, (or tanks) which may be part of, or form, a tower supporting the wind-driven rotor. A valve 16, controls flow of liquid from the tank 5, to an hydraulic turbine, which drives an electric generator 11. The valve 16 may be controlled by a pressure monitoring device 17, and a demand measuring device 18, and a computer and communications equipment 20, may be provided. The wind-driven rotor may be a vertical axis device (figure 3) and the tank 5, may be separate from the tower supporting the wind-driven rotor (figure 2).

Description

HYBRID WIND-HYDRO TURBINE DESCRIPTION This invention relates to a hybrid wind-hydro turbine of the type that generates electricity for use as either a stand-alone system or for supply to the national grid.
Other hybrid wind-hydro turbine designs use an elevated reservoir to store the potential energy of the water held there. Such designs require large reservoirs and generally require water to be pumped over long distances which is inefficient.
An object of this invention is to reduce the size of the reservoir required to store relative amounts of energy and to increase efficiency by reducing the distances over which liquid must be pumped for storage.
According to the present invention there is provided a hybrid wind-hydro turbine in which a rotor powered by the wind drives a pump compressing liquid into a gas pressurised storage tank or tanks for later release through a hydro turbine connected to a generator to produce electricity.
Preferably the pump, hydro turbine, generator and related electrical equipment would all be readily accessible at ground level.
The container used for the storage of the pressurised liquid may also comprise the tower of the turbine.
The electrical output of the hydro generator may be automatically controlled through the use of a device monitoring electrical demand which in turn controls the flow of pressurised liquid into the generator.
A preferred embodiment of the invention will now be described with reference to the accompanying drawing in which: Figure I shows a side view cross-section of a horizontal axis turbine where the rotor is mounted on a tower that also serves as a pressurised storage tank.
Figure 2 shows a side view cross section of a horizontal axis turbine where the rotor is mounted on an open frame tower similar to that of an electricity pylon rather than an enclosed column.
Figure 3 shows a side view cross section of a vertical axis turbine.
As shown in Figure 1, the turbine comprises a rotor 1 attached to a drive shaft 2. A bearing 12 allows the rotation of the drive shaft which is connected to a pump 3 Liquid is forced from the pump 3 into an increased pressure container 5 through the pump outflow pipe 4.
Liquid under pressure then leaves the increased pressure container 5 through the turbine inflow pipe 6. The liquid drives the hydro turbine 7 which is connected to the electricity producing generator 11.
Liquid leaves the hydro turbine by way of the turbine outflow pipe 8 and is stored in the low pressure container 9. Finally the liquid is drawn back into the pump through the pump inflow pipe 10.
Another bearing 13, allows the nacelle 14 and the attached rotor 1 and tail fin 15 to turn dependant on the wind direction.
The rate of flow to the hydro turbine 7 is regulated by a valve 16 which in turn is controlled by both the pressure meter 17 in the high pressure tank 5 and the electrical demand meter 18 connected to the electrical supply cable 19 Remotely accessed digital information relating to the operation of the hybrid windhydro turbine, including output of the generator 11 is recorded by a computer 20 which incorporates communications equipment
