The Vertical Tilting Blade Turbine Windmill device is for capturing kinetic energy from the wind and is comprised of a vertical shaft having a central hub connectively attached, the central hub having a plurality of wind capture arms comprising a rotating wind capture blade having a capture surface and a slicing edge that are rotated wherein the wind capture blades are rotated between a blade mode to capture the wind and a knife mode to pass with less drag resistance through the air/wind thereby enabling an increase in the ability to capture more of the energy available in an on-coming wind stream.

Proposed is a wind turbine having a vertical axis rotor mounted in a fixed cylindrical housing provided with outwardly opening shutters. The rotor consists of a rotating core comprising core blades fastened between two circular bases and forming a Ugrinsky rotor, and an annular impeller configured for independent rotation about said core. The impeller comprises impeller blades fastened between two ring-shaped bases and forming a continuation of the core blades, wherein common inter-blade channels are formed which narrow toward the centre of the rotor. Also proposed are wind power stations based on the wind turbines described above, said turbines being mounted vertically one above the other to form a generating tower, or being mounted on a facade of a high-rise building. Technical result consists, in particular, in increasing the efficiency of the wind turbine and making it possible to incorporate wind power stations into an urban environment.

Invention relates to renewable Wind energy combining drag and lift forces into usable torque, having adjustable blades panels with sub blades. Its unique feature is to convert reverse drag into usable lift and combine the two forces in to one cohesive force. The system comprises output drive rotor arranged on a tower base, with its rotating arms with blade panel assemblies mounted rotatably. Each blade panel assembly comprises an auxiliary rotary shaft having sub-blade panels pivotable at one or more pivot points with primary or secondary control arrangements for blocking and/or allowing wind to pass through the blade panels partially or fully. The system further includes sensors to collect control information, coupled to Main Control Unit (MCU) and secondary control arrangements, configured to provide one or more energy forms.

A method for storage of excess energy which would otherwise be lost, the regulation of angular velocity, and prevention of excessive velocities is disclosed. The device consists of a bowl shaped container, divided into sections by radially oriented vertical walls, which holds a fluid (any appropriate liquid or set of small solid particles), and spins on its vertically oriented axis at various angular velocities. The floor of the device is formed in successive shapes of bowls and shelves, which allows for a kind of “gearing”. The invention allows more and more energy to be input into the device while the angular velocity is regulated within a particular range. A typical embodiment of the invention would include its attachment by a shaft at the axis to a vertical axis wind turbine.

The present application discloses a power generation device so as to solve the generator set overspeed problem. The power generation device comprises: a stand column; and at least one generator set located on the stand column. The generator set comprises a support, blades connected to the support, and a power generator generating power by means of rotation of the blades, and an adjustment device located on the support and used for adjusting a windage area of the blades by moving or rotating the blade according to a wind speed. The wind power generation device may reduce an effective windage area to zero when the wind force is too high, thereby improving stability and applicability in a changeable environment and prolonging the service life of the apparatus.

Methods, systems, and devices for dynamic wind turbine rotational speed control are described. The method may include attaching a vane shaft to a support arm of the wind turbine, the vane shaft partially inserted into a cylindrical aperture of an airfoil of the wind turbine, rotating an airfoil around a vertical axis of the wind turbine, and controlling, via a torsion spring of the wind turbine, when a rear stop of the speed control assembly exerts a force on the airfoil to reduce the rotational speed of the wind turbine, where the torsion spring is configured to facilitate the rear stop to exert the force on the airfoil when a rotational speed of the wind turbine around the vertical axis exceeds a set rotational speed, where a portion of the vane shaft is inserted into a helical portion of the torsion spring.
