Problems solved by technology

The method is rather immature and provides very little measurement accuracy, apart from being completely useless for offshore wind farms, where the filming must be done on a floating platform, which further lacks accuracy in terms of position and movement

Embodiment Construction

[0066] The invention relates to a method for measuring and adjusting pitch in a wind turbine. To illustrate the invention, a wind turbine (11) of the type having three blades (15) is chosen, although this should not be construed as limiting, it is a simple way of describing the invention providing a clear description.

[0067] For simplicity and to make the description easier to understand, no wind farm is depicted in any of the figures, as it will be understood not to aid in clarity of the description. However, two types of wind turbines are distinguished in wind parks. One is a normal wind turbine (11) and the other is a model wind turbine (10), which is represented by the wind turbine producing the most power in the wind farm. The two wind turbines are identical except for the relative position of their blades (15), which make them produce more or less power.

Abstract

The invention relates to a method for measuring and correcting the angle of attack in a wind turbine farm (11), by which means the yield of each wind turbine (11) of the wind farm is measured initially in order to be able to define a model wind turbine which will be the one which generates the maximum power. The creation of coordinate axes for each blade (15) of the wind turbine (10) allows the angle of attack of the blades (15) of said model wind turbine (10) to be calculated and a reference value to be defined in order to copy same to each blade (15) of the rest of the wind turbines (11), in such a way that the optimum power ratio is obtained for each wind turbine of the wind farm.

Description

technical field [0001] The invention relates to a method for measuring and regulating the angle of incidence of wind, known as the angle of attack, on the blades of a wind turbine of a park. The angle of attack is particularly important for the output of a wind turbine, so the method of adjustment when installing the wind turbines of a wind park is of crucial importance. [0002] The invention finds particular application in the field of the renewable energy industry. Background technique [0003] When installing a farm for generating wind energy by means of wind turbines, the initial problem is to install the blades in the wind turbine with an appropriate reference angle of attack defined in the construction design and operating conditions. In other words, for example, when the control system of a wind turbine indicates 0°, it must be ensured that the section of the blade in which 0° has actually been defined has this angle of attack. [0004] This angle used as a referen...
