Session 2.1 Application of Artificial Neural Networks for Condition Monitoring of Wind Turbine Main Bearings – Niels Jessen, RWE Renewables

In a wind turbine, a failure of an important component, such as a main bearing, can lead to long-lasting downtimes and thus to a corresponding energy loss. In offshore wind energy, the problem is even more serious as maintenance work is not always possible due to adverse weather conditions and must be planned in advance. In order to save operational expenditure, wind farm operators are required to implement a maintenance strategy that enables them to predict a component’s failure as early as possible.

The RWE Renewables GmbH has developed an ANN based tool that predicts the temperature of undamaged main bearings based on a selection of SCADA signals. Anomalies are detected when the actual bearing temperature deviates from the predicted temperature. The tool was shown to be successful in detecting issues up to nine months before failure.

Session 2.2 Grid Fault Location Detection Using System Simulation and Machine Learning - Patrice Brunelle, Hydro Quebec; Graham Dudgeon, MathWorks

MathWorks and Hydro-Québec explore how both system simulation and machine learning can be used to develop algorithms that can detect the location of faults on electric grids using voltage sag measurements. System simulation is used to generate synthesized fault data that covers a broader operating envelope than measured data alone. The synthesized data is then used to train machine-learning classification algorithms. You’ll learn how the performance of classification algorithms may be used to provide further insight into the physical behavior of the system and any limitations associated with training data. You’ll also see how recommendations can be made from this insight to enhance system measurements and training data sets to improve overall classification accuracy.

Session 2.3 Signal Waveform Classification in Partial Discharge Applications for Underground Power Cables - Steffen Ziegler, IMCORP

Underground distribution cable system failures can be predicted! Predictive maintenance begins with understanding how cable system failures occur. Analyzing and interpreting results from partial discharge (PD) measurements taken in the field can be a complex task for humans. Machine learning algorithms and deep learning algorithms are used to automatically identify and categorize markers of defects contained in the PD measurements. These algorithms are used to categorize different defect types by risk of going to failures soon. Differentiating cables with “high to low risk defects” along with those that are “defect free” enables predictive maintenance. Examples of identified defects will be presented.
