FINO1 Wind Turbulence Characteristics

This repository offers MATLAB functions and a live script to visualize wind turbulence characteristics on FINO1. The data set is used in previous works, like [1,2,3].

Dataset

Access the data for this repository at the Zenodo repository: https://doi.org/10.5281/zenodo.8296894

Content

The repository includes:

• dataAnalysed: Folder with the data
• Documentation.mlx: LiveScript showcasing dataset usage
• label.m: Function for labeling figures
• mergeStructs.m: Function to concatenate data
• binAveraging.m: Data binning function

Usage

First, ensure the data is in the dataAnalysed folder. If missing or misplaced, download from the linked Zenodo repository.

Execute the LiveScript to visualize the turbulence characteristics. Ensure MATLAB's directory is set to include the script and dataAnalysed folder.

Note: This is the initial submission and may contain bugs.

Relevance and Applications

• Validation of turbulence models like Kaimal or Mann for wind load calculations
• Analysis of single-point auto-spectral and cross-spectral densities of wind turbulence.
• Evaluation of standards, e.g., IEC 61400-1 and IEC 61400-3, for wind turbine design.
