摘要： A method is disclosed for estimating the surface condition of a blade rotating about a rotational axis in an air or fluid stream. The method involves measuring blade deformations indicative of blade loads acting on the blade to identify actual blade loads (P,R,T), measuring blade-state information (Ψ,Ω,,V) indicative of a blade operational state to identify a given blade operational state (α,Q), providing a clean-surface aerodynamic map (c) relating blade loads to an ensemble of blade operational states when the blade surface is in a clean state, providing a dirty-surface aerodynamic map (d) relating blade loads to an ensemble of blade operational states when the blade surface is in a dirty state, estimating the surface condition of the blade by comparing the distance of the actual blade loads (P,R,T) to the blade loads given by the clean-surface aerodynamic map (c) at the given operational state (α,Q), and the distance of the actual blade loads (P,R,T) to the blade loads given by the dirty-surface aerodynamic map (c) at the given operational state (α,Q).

摘要： An angular position encoder for a rotating shaft is disclosed, in particular for application on the rotor shaft in wind turbines. A materialized measure in the form of a roller chain is arranged around the circumference of the shaft. A scanning head in the form of a sensor is arranged at a distance from the materialized measure and scans the surface of the materialized measure as the shaft is rotating. A measurement value evaluation unit processes recorded measurement values to give positional and/or speed data on the shaft. A method for determination and measurement of the rotor speed or position for a rotating shaft by means of the angular position encoder is also disclosed which includes determination and measurement of the rotor speed or position, creating or mapping at least one reference pattern or map of the chain, and a comparing the pattern and an actual measurement value.

摘要： The invention relates to a method for pitch angle measurement and/or for constructing a pitch angle measurement system on a rotor blade (100) of a wind turbine, the rotor blade comprising a blade root (114) and extending along a longitudinal blade axis (180). The rotor blade is rotatably mounted, by its blade root (114), to rotate about the longitudinal blade axis (180), on a rotor hub (20) of the wind turbine, the rotor hub rotating or being rotatable about a rotor axis (36). At least one chord line direction indicator (430) is firmly connected to the rotor blade (100) at a distance from the blade root (114), and defines a chord line direction indicator direction (160) indicative of a direction of a chord line (140) of the rotor blade (100) at the location of the chord line direction indicator (430). The rotor blade (100), or at least one rotor blade portion (101) of the rotor blade firmly connected to the chord line direction indicator (430), is produced in a mould (200) before being connected to the chord line direction indicator (430). While the rotor blade (100) or rotor blade portion (101) is in the mould (200), the chord line direction indicator (430) is firmly connected to the rotor blade (100) or rotor blade portion (101) in a position which is defined relative to the mould (200).
