The present invention relates to a wind turbine with blade pitch system with an angle between the longitudinal direction of the blade and axis of rotation of the bearing of the blade pitch system, disposing the driving plate of the blade pitch system between the blade and the bearing of the blade pitch system.

It allows a more complete cooling of the generator, comprising: a magnetic core with a crown (

Precast segment for wind turbine tower especially designed to be used in wind turbine towers installed in cold climates, and which comprises joint flanges showing a configuration intended to establish the boundaries for forming the joints between said precast segment and an adjacent precast segment and which comprises conduits provided with an inlet and an outlet, situated in the proximity of the joint flanges of the precast segment intended to house some heating cables that generate heat. The method comprises the use of the described precast segment and the stages of introducing heating cables in the conduits of the precast segment, applying current to said cables and removing the cables when a filler material used in the joint between precast segments has set.

The invention describes a process and a unit, both enabling to attach a wind turbine tower to a foundation, as well as describes also a wind turbine incorporating the unit. The process features a stage of installation of a support element for the transmission of stresses from the tower to the foundation, followed by a stage of leveling the support element and pouring foundation concrete up to the support elements lower side so that the lower side is adhered to the poured concrete once it has set. The unit comprises at least one support element.

The present invention can be included in the technical field of power control systems of electrical generation units comprising a supervisory regulation link applicable to a generation unit which calculates operating parameters or orders based on temporary averages of the power measurement.
