Method for calculating and correcting the angle of attack in a wind turbine farm comprising: - a tower, - a nacelle, - a hub, - blades, characterized in that: - a model wind turbine is defined as the wind turbine that generates maximum power from among all the wind turbines of the farm, - a coordinate system GXYZ is created in a first blade of the model wind turbine, comprising: - measuring at least three points of the front face of the nacelle where it is attached to the hub, defining an AB plane, - measuring at least three points of the circumferential contour of attachment of the first blade to the hub, defining a circular section the center G of which is the origin of the coordinate system of this first blade, - defining the X axis as an axis that is perpendicular to the circular section and passes through the origin G, - defining the Y axis as an axis that is perpendicular to the X axis, that is parallel to the AB plane and passes through the origin G, - defining a third Z axis as an axis that is perpendicular to the previously defined X axis and Y axis and passes through the origin G, - the angle formed between a reference straight line formed by the joining of two points (22, 23, 24, 26, 27) defining the cross-section of the first blade at any one distance from the origin G in the direction of the X axis and the rotor plane of rotation is calculated, obtaining a reference angle (α), - the angle of attack of the first blade is calculated as the complementary angle of the reference angle (α). - a tower, - a nacelle, - a hub, - blades, - a model wind turbine is defined as the wind turbine that generates maximum power from among all the wind turbines of the farm, - a coordinate system GXYZ is created in a first blade of the model wind turbine, comprising: - measuring at least three points of the front face of the nacelle where it is attached to the hub, defining an AB plane, - measuring at least three points of the circumferential contour of attachment of the first blade to the hub, defining a circular section the center G of which is the origin of the coordinate system of this first blade, - defining the X axis as an axis that is perpendicular to the circular section and passes through the origin G, - defining the Y axis as an axis that is perpendicular to the X axis, that is parallel to the AB plane and passes through the origin G, - defining a third Z axis as an axis that is perpendicular to the previously defined X axis and Y axis and passes through the origin G, - measuring at least three points of the front face of the nacelle where it is attached to the hub, defining an AB plane, - measuring at least three points of the circumferential contour of attachment of the first blade to the hub, defining a circular section the center G of which is the origin of the coordinate system of this first blade, - defining the X axis as an axis that is perpendicular to the circular section and passes through the origin G, - defining the Y axis as an axis that is perpendicular to the X axis, that is parallel to the AB plane and passes through the origin G, - defining a third Z axis as an axis that is perpendicular to the previously defined X axis and Y axis and passes through the origin G, - the angle formed between a reference straight line formed by the joining of two points (22, 23, 24, 26, 27) defining the cross-section of the first blade at any one distance from the origin G in the direction of the X axis and the rotor plane of rotation is calculated, obtaining a reference angle (α), - the angle of attack of the first blade is calculated as the complementary angle of the reference angle (α).
