Abstract
The wind energy sector grew continuously in the last 17 years, which illustrates the potential of wind energy as an alternative to fossil fuel. In parallel to physical architecture evolution, the scheduling of maintenance optimizes the yield of wind power plants. This paper presents an innovative approach to condition monitoring of wind power plants, that provides a system-level anomaly detection for preventive maintenance. At first a data-driven modeling algorithm is presented which utilizes generic machine learning methods. This approach allows to automatically model a system in order to monitor the behaviors of a wind power plant. Additionally, this automatically learned model is used as a basis for the second algorithm presented in this work, which detects anomalous system behavior and can alarm its operator. Both presented algorithms are used in an overall solution that neither rely on specialized wind power plant architectures nor requires specific types of sensors. To evaluate the developed algorithms, two well-known clustering methods are used as a reference.
