Abstract

A wind driven generator having e.g. a 60 ft. dia. wind wheel and generating up to 30 KW, drives four hydraulic gear pumps through step up gearing. A transducer ensures that only one pump is on torque at low speeds, but further pumps are on torque at higher speeds. The pumps one fed from a header tank, and the hydraulic fluid then passes to a piston and cylinder device loaded with a ballast weight. When pressure rises due to increased wheel speed, the piston operate valves are limit switches and a 5KW hydraulic motor is operated to drive an induction generator. For higher wind speeds, the piston rises further and a second hydraulic motor is operated to drive a generator connected to a resistive load for heating. All these devices are operated intermittently as the wind speed varies. At very high speeds, spoilers or flaps on the blades of the wheel can be operated, reducing the efficiency. The first generator can be used to return power to the local mains. The second generator can have a capacity of between 25 and 30 KW.
