AI Algorithms
This section explores the performance of various machine learning algorithms—Decision Trees (DT), Support Vector Machines (SVM), K-Nearest Neighbors (KNN), and Multilayer Perceptrons (MLP)—in detecting and localizing cracks in wind turbine blades. Each algorithm was evaluated based on accuracy, training time, and prediction speed under different dataset sizes and feature sets.
Data Preprocessing
Effective data preprocessing is crucial for building successful AI models. This involves normalization, feature extraction (from time series data, capturing statistical, temporal, and spectral properties), feature selection, and feature intersection to reduce problem size and improve model performance.
Crack Detection
The study focuses on identifying the presence of cracks, determining which blade is cracked, and pinpointing the exact location of cracks (tip, mid, or root) in rotating wind turbine blades using root vibration signals. This real-time, non-invasive approach is vital for early fault detection, preventing catastrophic failures, and minimizing maintenance costs.

Case Study: Predictive Maintenance in a 500W Wind Turbine
A small wind turbine (50W-500W) experienced frequent, unscheduled downtime due to undetected blade cracks. Post-implementation of the AI monitoring system, leveraging KNN algorithms, the turbine observed a 99.96% accuracy in identifying and locating cracks in real-time. This led to proactive maintenance, extending blade lifespan by 30% and reducing emergency repair costs by 45%. The system's ability to operate non-invasively without interrupting energy production was key to achieving these results.
