Embodiment Construction

[0037] Reference will now be made in detail to the embodiments of the subject matter, one or more examples of which are shown in the accompanying drawings. Each example is provided in a way that explains the subject rather than limiting the subject. In fact, it is obvious to those skilled in the art that various modifications and variations can be made to the subject without departing from the scope or spirit of the subject. For example, features shown or described as part of one embodiment can be used in another embodiment to obtain yet another embodiment. Therefore, this subject matter is expected to cover these modifications and variations that fall within the scope of the appended claims and their equivalents.

[0038] figure 1 A perspective view of the wind turbine 10 is shown. As shown in the figure, the wind turbine 10 is a horizontal axis wind turbine. However, it should be understood that the wind turbine 10 may be a vertical axis wind turbine. In the illustrated emb...

Abstract

The present application relates to a system and a method for monitoring and controlling wind turbine blade deflection. A system is disclosed for monitoring and controlling the deflection of turbine blades (22) of a wind turbine (10). The system includes a passive position detecting apparatus (46) and a controller (36). The passive position detecting apparatus (46) may be configured to acquire and transmit data relating directly to a position of at least one of the turbine blades (22). The controller (36) may be configured to receive the data from the passive position detecting apparatus (46) and compare such data to a known position reference to determine turbine blade deflection.

Description

Technical field [0001] The subject matter generally relates to wind turbines and particularly to turbine blade deflection. More particularly, the present subject matter relates to systems and methods for monitoring and controlling wind turbine deflection during wind turbine operation. Background technique [0002] Wind power is considered to be the cleanest and most environmentally friendly energy currently available, and wind turbines have received increasing attention in this regard. Modern wind turbines usually include a tower, generator, gearbox, nacelle, and one or more turbine blades. Turbine blades use the known foil principle to capture kinetic energy from the wind and transmit the kinetic energy through rotational energy to turn the shaft, which connects the rotor blade to the gearbox, or directly to the gearbox if the gearbox is not used. generator. The generator then converts the mechanical energy into electrical energy, which can be deployed to the grid. [0003] To...
