Wind Turbine SCADA Data Modeling and its Application

Wind turbine power curve contains a large number of operational information, it helps to know the equipment operation state if we can analyze these data in a scientific way, it can also help to improve the wind turbine's reliability. This article focuses on two kinds of SCADA data modeling method: the first is parametric modeling based on logistic function, the second is high precision modeling based on least squares. These two methods were used to establish the wind turbine power curve models and the models can be used for condition monitoring when combine with control charts method. It is proved in the industrial case study that this method can detect abnormal SCADA data of wind turbine efficiently.
