Procedure and apparatus for monitoring wind turbine components based on conditions

摘要

A wind turbine that has monitoring capabilities based on conditions, comprising: a sensor (200) coupled to detect the movement of a component (175) of the wind turbine from a base position and to generate one or more signals (650 ) that indicate movement; and a control circuit (210) coupled with the sensor (200) to receive one or more signals indicating the movement, to perform a monitoring operation based on the conditions based on the one or more signals and to selectively generate a signal output based on the condition-based monitoring operation, characterized in that the condition-based monitoring operation comprises the evaluation of fatigue due to precipitation, and in which the sensor comprises at least one of: a sensor (310 ) of proximity to detect the movement of a flange of the main shaft (300), a set of proximity sensors (1110, 1120, 1130) oriented towards the shaft (1100) to detect the displacement of the shaft with respect to a relatively non-component deflector, two proximity sensors (310, 340) oriented towards the shaft and also in which the two sensors are approximately 90 ° apart from an axis in sec transverse axle of the tree, four proximity sensors (310, 320, 330, 340) oriented towards the tree, and also in which the four sensors are approximately 90 ° apart from the axis of the tree and two pairs of proximity sensors oriented towards the tree, and also in which the two pairs of sensors are approximately 90 ° apart from an axis in cross-section of the tree.
