The invention relates to a method for operation of a wind energy plant, comprising the steps: recording the values of given operating parameters by means of suitable sensors, recording at least one given limiting condition, comparison of the recorded values with stored values of the operating parameters. The invention further relates to a wind energy plant for carrying out said method. The aim of the invention is thus to be able to match the operation of a wind energy plant to changing conditions, whereby, according to the above method, if differences between the recorded parameters and the stored parameters occur and depending on the limiting condition, either the stored parameter values are matched to the recorded parameter values, or the operation of the wind energy plant is altered, depending on the recorded parameter values. According to the invention, on pragmatic grounds, icing of a rotor blade is considered a (temporary weather-induced) change to the rotor blade form. Icing of the rotor blades thus always leads to a change in the aerodynamic profile and hence to a reduction in output of the wind energy plant. However, manufacturing tolerances lead to deviations from the optimal form of the rotor blades and also gradual contamination of the rotor blades during operation lead to deviations from said form and thus changes in the amount of power generated. |
