Abstract: A method of monitoring the condition of a wind turbine. The method includes the steps of selecting a plurality of measurable parameters indicative of the operational state of the wind turbine; recording measures of a variable indicative of the condition of the wind turbine during a period of normal operation thereof, and deriving corresponding values of a characteristic quantity from said measures; recording measures of the parameters during the same period; identifying a correlation between the characteristic quantity and at least one correlated parameter; and from said correlation, defining the expected value of the characteristic quantity as a target function that is a function of said at least one correlated parameter.
