A wind or water flow (hydrokinetic) turbine for harnessing a predetermined minimum or baseload value of renewable electric energy from the wind or water flow energy received at a harnessing module comprises the harnessing module, a controlling module, and a generating module. Han's Principle is that, in a torque balanced three variable Hummingbird speed converter system, from a harnessed input power (input), the generated electric power (output) must exceed the electric power used for the control power (control input) and the input power must exceed the summation of control power and output power. Harnessed input power is provided to a power-balanced three variable mechanical gear control system when a control power of power versus load graph is crossed by an output power line graph to achieve an electrical advantage at a generator output. The three variable mechanical motion control system or "motionics" comprises a Hummingbird control assembly of first and second spur/helical/bevel/miter/ring gear assemblies or Transgear assemblies with an adjustment in between to eliminate variations from constant rotational speed input. The Hummingbird mechanical variable to constant speed control, a control motor and a generator among other components may be mounted on land or a floating platform. Constant electric power at constant frequency are delivered to a variable load.

CN_109838351_A

Resumen de: AU2018371270A1

A self-aligning to the incoming wind floating platform supporting multiple wind turbines(17, 18) forms a wind power generation unit. Under horizontal wind, the wind load resultant passes the center of geometry of the wind load receiving areas (hereafter C.Geo) of the floating platform, but not the turning axis (15), resulting a yaw moment about the turning axis (15) to turn the floating platform until the wind load resultant passes through the C.Geo and the turning axis (15) simultaneously. A wind park or wind farm comprises at least one floating platforms capable of self-aligning to the incoming wind for electric power generation. The floating platform helps to reduce the mileage of the submarine power cable (44), hence reducing the electric resistance and subsequently heat loss, and reducing the cost of submarine power cables (44).
