Embodiment Construction

[0007]The present invention discloses a wind turbine that solves the problems of the prior art allowing the removal of ice from the blades with less energy consumption than the devices of the prior art. Also, it does not require substantial modifications in the structural design of the blades.

[0008]Specifically, the present invention discloses a wind turbine of the type comprising:[0009]a rotor having at least two blades;[0010]a control system;[0011]means for detecting the presence of ice on the blades;[0012]a heating system having at least one heating element configured to carry out a heating stage of at least one of the blades.

[0013]Preferably, the heating system is connected to the control system and is configured to carry out a heating stage of at least one of the blades by activating the power supply of at least one heating element disposed in each of the blades. To this purpose, the control system comprises at least one ice removal routine that comprises the following stages:[...

Abstract

A wind turbine is disclosed which comprises a control system configured to execute at least one ice removal routine which comprises a heating stage of at least one of the blades (3), and a mechanical removal ice stage. A wind turbine removing ice method is also disclosed which comprises a stage wherein the presence of ice is detected on at least one of the blades and, once said presence of ice is detected, comprises a stage wherein at least one ice removal routine is activated which comprises, in turn, a heating stage of at least one of the blades and a mechanical removing ice stage on at least said blade.

Description

OBJECT OF THE INVENTION[0001]The present invention belongs to the field of energy generation by means of wind turbines. In particular, the present invention relates to a wind turbine having the capacity of removing ice deposited on its blades and a removing ice deposited in the wind turbine blades method.BACKGROUND OF THE INVENTION[0002]The deposition of ice or other type of unwanted material on the wind turbine blades causes inadequate operation in terms of production and loads. This is due to the variation in the aerodynamic and mass characteristics of the blades, partly due to the modification of the geometry of the aerodynamic profiles. This variation in aerodynamic profiles can even cause aerodynamic loss in certain parts of the blade. Said variation can result in an increase in wind turbine loads and vibrations.[0003]The prior art proposes different solutions to try to solve the previously described problem.[0004]Therefore, there are systems for removing and / or preventing ice ...
