Abstract

From the analysis and arragment of historical data of wind turbine pitch motor temperature wind speed and other related parameters of hebei chigu wind farm in 2015 ,the paper obtains historical data using 10 minutes as acquisition unit under various operating conditions of wind turbine pitch system from SCADA system,puts forward a method that establish a health model of the operation of variable pitch system using the method of piecewise polynomial curve fitting,then predict the change trend of the parameters of real time condition according to this health model and judge the residual error between actual value and predicted value based on the method of sliding window residual mean.Finally identify the abnormal operation condition of the variable pitch system combined with practical experience in the field.Verified by historical data,this method can findout the abnormal state of variable pitch system in time and make accurate judgment so as to eliminate the hidden trouble.It has a high practical value for the economic operation.to wind field.
