The invention concerns a method for automated surveillance of at least one wind turbine (41), comprising the following process steps (21, 23, 18, 205 26, 27, 28, 29). One step is to create or retrieve at least one linear model (21, 23, 18) which represents at least one status parameter of the wind turbine (41) and which comprises a plurality of linear coef-ficients and at least one measurement variable, whereby the values of the linear coefficients are determined based on test measurement values (MVt) for the measurement variable and the status parameter of the wind turbine (41). Another step is to repeatedly capturing (25) momentary measurement values (30) for the measurement variables and the status pa-rameter of the wind turbine (41). A further step is to deter-mine (26) at least one momentary reference value of the status parameter based on the momentary measurement values for the measurement variables by using the linear model. An-other step is to generate wind turbine status information (29) based on the deviation of the momentary measurement value from the corresponding momentary reference value of the status parameter. The invention also concerns a monitoring apparatus for such a surveillance and a method for creating a linear model for use in the method or the monitoring appara-tus mentioned above. |
