Wind turbines are of growing importance in our energy supply. A failed turbine can have major consequences for communities depending on it. How can Artificial Intelligence help in predicting failure and in-time maintenance?

Challenge

Creating an all-weather prediction model

Wind turbines are stationed from the north pole to the desert, in urban areas and at sea. The difficult accessibility and extreme weather conditions turn maintenance of turbines into a challenging job. Therefore it is of crucial importance to foresee a defect. The growing complexity of turbines make it harder for engineers to interpret data. For this reason Bit was asked by an international energy supplier to prototype a machine learned predictive maintenance tool.

Outcome

2 years

of historic data

26 turbines

monitored

4 seconds

of model training

Hypothesis

Bearing temperature as key indicator

Wind turbines consist of moving and fixed parts. These parts meet inside a bearing, causing friction and heat that produces energy. Lubricating oil is used to prevent the temperature within the bearing from becoming too high. An abnormality in this bearing temperature is a good indicator for deviating behavior. This was the key hypothesis for our jumpstart.

Research and prototyping

Historic data to predict the future

Using bearing temperature as the single indicator for failure would only work under specific turbine and weather conditions like cold, heat and wind. Therefore technically experienced engineers and data driven experts trained a model including a variety of features like outside temperature and turbine spinning speed. Within weeks the model was able to accurately reproduce the historic data, indicating the model would be able to predict future failures. During a prototype demo, a recently noticed aberration in one of the turbines came up. The perfect moment to check if our model had noticed too. And guess what?

Outcome

We finalized the project by implementing a control panel in our clients control room, assisting the engineers with machine based predictive maintenance.
