ABSTRACT:
The shaft of a wind driven propeller is coupled to the rotor shaft of an electrical generator through an over-running centrifugal clutch and a speed changer mechanism. When the wind attains a certain velocity, a propeller shaft speed responsive device closes a switch that connects the output terminals of the generator to an energized electric distribution system so the generator runs as a motor long enough to accelerate up to rated speed and concurrently get the speed changer mechanism up to speed. The clutch engages the propeller shaft to the speed changers at this time and the generator begins to supply supplemental power to the system. Because all rotating parts are brought up to matching speeds together, the inertia shock that would result from connecting the propeller to a speed changer and generator that are at a standstill is avoided. When wind velocity drops, the generator runs as a motor for a moment and causes the over-running clutch to disengage.
