# 5MW Wind Turbine Drivetrain Bearing Damage Dataset

## Dataset Description
Dataset containing vibration signals from the NREL 5MW reference drivetrain model with different bearing conditions.
The reference paper for this dataset is available at: [DOI: 10.1016/j.renene.2022.12.049](https://doi.org/10.1016/j.renene.2022.12.049)
This is a subset of the original dataset available at Zenodo. For the full dataset and additional information, please visit: [DOI: 10.5281/zenodo.7674842](https://doi.org/10.5281/zenodo.7674842)


### Features:
- **`signal_a1a`**: Vibration time waveform from sensor A1A
- **`signal_a3a`**: Vibration time waveform from sensor A3A
- **`signal_length`**: Length of the signals
- **`label`**: Fault condition (0: healthy, 1: main bearing, 2: high-speed bearing, 3: low-speed planet bearing)
- **`environmental_condition`**: Operating conditions (EC1, EC2, EC3)
- **`sampling_frequency`**: 200.0 Hz
- **`wind_speed`**: Operating wind speeds (7.0, 12.0, 14.0 m/s)

### Data Split
The dataset includes samples from:
- **4 different conditions** (healthy + 3 fault locations)
- **3 different operating conditions** (EC1, EC2, EC3)
- **Total of 12 different scenarios**
