Abstract: A method for predictive monitoring of the condition of wind turbines is disclosed. The method may include selecting at least one wind turbine inside a wind farm and at least one component of the wind turbine; acquiring SCADA data comprising operational data of the wind farm and temperature values of the at least one component of the wind turbine during a preselected time period, calculating differential data as a difference between the temperature values of the selected turbine component of the selected wind turbine and an average temperature of the selected wind turbine component in at least two wind turbines in the wind farm; defining a monitoring time period to monitor the component; calculating at least one predetermined statistic of the differential data during the monitoring time period, and saving the predetermined statistic as a monitoring feature; and testing if at least one monitoring feature exceeds a threshold value.
