Abstract
Status monitoring of a wind turbine is automatically performed, and evaluation of that status is quantitatively performed according to an appropriate criterion. Provided is a wind turbine monitoring device including a first storage unit in which a diagnostic data file is stored; a second storage unit in which a normal data file is stored; a diagnostics setting unit that that extracts and sets a plurality of datasets to be used in diagnosis from the first storage unit and that extracts and sets a plurality of datasets to be used in diagnosis from the second storage unit; an index-value calculating unit that calculates status index values representing the status of the wind turbine using a statistical calculation method, on the basis of the set datasets in the diagnostic data file and the datasets in the reference data file; a fault determining unit that evaluates the status of the wind turbine on the basis of the status index values; and a notification unit that notifies the result of this evaluation.
