A system comprised of common Industrial Control System components, used to accurately, positively, and independently position turbine blades to be continuously re-positioned in the optimum position with respect to the flow direction. This system would apply to Vertical Axis Wind Turbines (VAWT's), Tidal, Ocean Current, or River turbines where it is desirable to orient each blade in a specific position during the rotation of the turbine. The positioning of the blades is accomplished by an actuator which is attached to the shaft of the rotatable blades. The actuator position control is accomplished by creating an absolute relationship between the direction of the flow (either water or air), the turbine, and the turbine blades. The turbine blade position, flow direction, and turbine position are determined by encoders attached to the turbine frame and the input shafts of the encoders being oriented by the blades and the flow direction. |
