A present invention describes unique wind turbine assembly in a shape of closed hollow cylinder formed by two sets of three adjustable to positive and negative pitch horizontal blades supported instead of central shaft by three vertical cylindrical blades, which makes this turbine responsive to omni-directional wind. Proposed design concept provides with: Significant increase of turbine efficiency exceeding 60%, which after coupling this rotor with a generator of 60% efficiency leads to overall wind generator efficiency exceeding 40%. Low turbine inertia requiring moderate start up winds and reducing turbine vibrations. Noiseless turbine operation due to its rotation around vertical axis. Environmental friendliness as low operating speed does not generate strong turbulent air flow capable to challenge birds and bugs existence. No electronic control of blades angle of attack. Ease of manufacturing and maintaining together with their reduced cost.
Conducted analysis of the proposed configuration of the wind turbine shows no necessity of additional top support for a personal use wind generator, while requires one for more powerful (community) wind turbines. Proposed additionally supporting turbine tetrahedron beam frame resolves this issue allowing increase of power of such wind generators.

The wind turbine includes a wind driven turbine wheel rotatable about a central axis that has blades with streamers of other articles to fill the space between the blades. A set of streamers can be attached to the trailing edge of the blades at one end and including a free end wherein the free end is disposed in a space defined between adjacent blades. The streamers can also be attached to spokes.

The invention relates to a method for limiting structural loads in a wind turbine in situations where the power produced by the wind turbine is increased or decreased. The limitation of structural loads is achieved by restricting the power ramp rate, i.e. the rate of change of increases or decreases in produced power. The restriction is only invoked if a maximum change of the produced power or the corresponding internal power reference within a time window exceeds a given threshold.
