A set of upper and lower braces (26) connects the turbine blades (24) to prevent any sag or skewing of the turbine blades as they rotate about the tower.

The blades are provided with movable baffles (23) that can close or adjust the tilt of the blades.

The method comprises the sequential steps of: reducing the generated power, allowing an intermediate increase in the generator speed, and - reducing the generator speed by a means of pitching the wind turbine rotor blades.

The vanes (48) are controlled by sensing the inlet and outlet pressure at the vanes and adjusting the vanes in accordance with these pressures in order to maximize turbine efficiency.

A set of upper and lower braces (26) connects the turbine blades (24) to prevent any sag or skewing of the turbine blades as they rotate about the tower.

The invention further relates to a wind turbine (1) comprising at least two pitch controlled wind turbine blades (5) and pitch controlling means for pitching the blades (5).

The blades include first-type blades and second-type blades, the second-type blades having a different shape from the first-type blades.

The hub includes primary fan blades and splitter blades disposed between pairs of the primary fan blades.

The rotary blade body includes a blade support pipe and rotary blades.

The skewing ensures that those turbine blades that are attached to the diametrically-opposite points move on a helical trajectory with respect to the axis of rotation.

The system may also include various means coupled to the hub and to the first and second blade portions to adjust a pitch of each of the first and second blades.

The stationary blade body includes support rims, stationary blades, and elastic parts.

In a possible variant of the embodiment, the blades are provided with shaped grooves formed within the borders thereof.

Each of the blades is provided with channels.

A blade system for capturing wind power includes blades (21) and blade brackets.
