Using operational data to detect problems in wind turbines

What is it about?

This review summaries the efforts undertaken to use operational data for detection of problems in wind turbines. Operational data means here measurements recorded by the so called SCADA system which covers e.g. wind speed, pitch angle, power output, rotational speeds, temperatures. These signals are commonly available in 10 minute resolution and can be seen as not dedicated to failure detection. However, many different attempts have been undertaken to use these freely available data to increase the knowledge of the turbine's health.

Why is it important?

This review will enable you to find and assess all relevant approaches and understand the open questions and needs for future studies in this area. There are many review papers discussing condition monitoring of wind turbines, but we are not aware of any previously published review focusing on the variety of SCADA-based condition monitoring.
