Wind power generation device with real time pitch actuation

A power generation device, comprising:

• a generator connected to a shaft of a vertical rotor apparatus,
• wherein the vertical rotor apparatus rotates in response to wind,
• wherein the shaft is configured to transfer mechanical energy from the vertical rotor apparatus to the generator, and
• wherein the vertical rotor apparatus comprises:
• the shaft defining an axis of rotor rotation;
• a plurality of rotor blades longitudinally aligned in parallel with the shaft, each rotor blade defining an axis of blade rotation;
• a sensor to determine whether any of the rotor blades are within rotor azimuthal angles of blade stall regions, wherein the sensor comprises:
• a fluid vane configured to indicate wind direction;
• contact wires connected to the fluid vane and displaced with rotation thereof, the contact wires defining the blade stall regions as a function of the wind direction;
• and
• a contact sensor mounted proximally to the shaft and moving through azimuthal angles therewith, the contact sensor generating a signal in response to contacting the contact wires;
• a controller to provide blade pitch information for blade stall regions;
• and
• an actuator mechanically coupled to each of the rotor blades to alter blade pitch about the axis of blade rotation in accordance with the blade pitch information so as to avoid blade stall for all rotor azimuthal angles.
