A wind operated electrical power generating system, comprising:
- a wind turbine comprising a turbine blade assembly attached to a turbine blade subassembly shaft, said turbine blade subassembly shaft being rotationally carried by a turbine housing, said turbine housing being supported by a vertical riser support structure, the turbine blade assembly comprising:
- a hub having a hub radius defined from a hub center to an exterior edge of the hub,
- a turbine outer rim having a rim radius defined from a rim center to an interior edge of the rim,
- a plurality of spokes extending between the turbine outer rim and the hub,
- each spoke having a radial free spanning dimension extending between an outer edge of the hub and an interior surface of the turbine outer rim;
- and
- a plurality of turbine blades, each turbine blade having:
- a leading edge assembled to a respective spoke,
- a trailing edge assembled to a different respective spoke,
- an outer edge located proximate the interior surface of the turbine outer rim,
- an inner edge located between the outer edge and the interior surface of the turbine outer rim,
- a turbine blade radial dimension extending in a radial direction between from the outer edge of each turbine blade and the inner edge of each turbine blade,
- wherein the radial blade dimension is less than half of the radial free spanning dimension of the spoke,
- wherein the turbine blade assembly is designed to rotate at a slow rotational speed;
- a generator in one of direct and indirect operational communication with said turbine blade subassembly shaft, wherein rotation of said turbine blade subassembly shaft provides power to rotate an input shaft of said generator;
- a rotational speed sensor arranged to sense a rotational speed of one of said turbine blade subassembly shaft and said generator shaft;
- an electrical controller circuit in signal communication with said rotational speed sensor, wherein said electrical controller circuit identifies when a rotational speed of one of said turbine blade subassembly shaft and said generator shaft determined by a signal from said rotational speed sensor is a predetermined speed;
- and
- at least one variable resistor, wherein said at least one variable resistor is placed in electric communication with the generator, wherein each said at least one variable resistor is adjusted to optimize an electrical power output, based upon and associated with a respective of said predetermined rotational speed of one of said turbine blade subassembly shaft and said generator shaft,
- wherein a change in resistance by said at least one variable resistor changes a load upon said generator,
- wherein said predetermined rotational speed of one of said turbine blade subassembly shaft and said generator shaft that is a stall speed of the turbine blade assembly,
- wherein the load acts as a braking system, which adjusts a rotational speed of said generator shaft, which in turn adjusts the rotational speed of the turbine blade subassembly shaft wherein said at least one variable resistor are adjusted to a resistance that maintains a rotational speed of the turbine blade assembly to remain at or above a rotational speed that would cause stall of the turbine blades.
