Abstract

1514995 Wind motors H LAWSONTANCRED BART 19 July 1976 [17 July 1975 21 July 1975 15 Sept 1975 3 Dec 1975] 29947/75 Heading F1T In a system for generating electric power from wind energy, the energy derived from the wind is accumulated and used to drive a generator at constant power when the amount of accumulated energy exceeds a predetermined value. In the system shown, a 3-bladed, fixed-pitch wind wheel 11 drives four hydraulic gear-pumps 17a-d via step-up gearing 16. A shaft speed transducer 18 controls by-passes on three of the pumps such that at low shaft speed only one pump is operational while the other pumps become operational in turn as the wind speed increases. This ensures that the collective torque of the pumps is roughly proportional to the square of the wind wheel speed. The pumps draw fluid from a head tank 19 and deliver it to an accumulator comprising a cylinder 21 with a weighted piston 22. When the piston rises sufficiently to trip switch 27, a valve 24a is opened to connect the accumulator to a motor 24 driving a mains-energized 5kW induction generator. If the piston continues to rise and trips switch 28, a valve 25a is opened to connect the accumulator to a motor 25 driving a self-energized 25kW induction generator. Valves 25a, 24a are closed when switches 27, 26 are tripped by the piston during its downward movement. At an upper position, the piston trips switch 29 to open a by-pass valve 34 to permit fluid to be dumped back to the header tank via an orifice 35. The 5kW generator may be directly connected to the mains to feed power thereto (via a consumption meter to drive the meter in reverse) whenever the local load is less than 5kW. A brake 36 is actuated at very high wind speeds and in the event of a mains failure, and the blades of the wind wheel may have flaps or spoilers which are extended automatically to limit the speed of the wheel during high winds. In an alternative arrangement a single 30kW generator is used and connected directly to the mains. The power generated can alternatively be stored in batteries or used to generate heat for storage in underground tanks or to effect a chemical reaction such as the electrolysis of water to produce combustible hydrogen gas.
