# Wind Turbine Parameter Generation Method Based on Height Variation
This article explains how to process wind turbine parameter files using MATLAB scripts to generate wind pressure distribution data that varies with blade height. This method is suitable for aerodynamic load analysis in wind power generation systems.
## Core Workflow Analysis
Parameter File Reading
The script "Wind2.m" begins by reading the "wind turbine parameters.txt" file, which should contain fundamental turbine parameters such as hub height, blade length, and other critical dimensional parameters. The implementation typically uses MATLAB's file I/O functions like `fopen` and `textscan` to parse the input data.
Wind Pressure Distribution Calculation
Based on input parameters, the script calculates wind pressure distribution along the blade span. The calculation must account for height effects on wind speed (wind shear effect), typically implemented using logarithmic law or power law wind profile models to compute wind speed values at different heights. The code would incorporate mathematical expressions like V(z) = V_ref*(z/z_ref)^α for power law implementation.
Result File Generation
The final output generates a "wind speed and pressure distribution.txt" file containing two core data columns:
First column: Relative height position from hub center
Second column: Wind pressure value (Wind pressure2) at corresponding height
The MATLAB implementation would use `fprintf` or `writematrix` functions to export the calculated results in tabular format.
## Technical Key Points Explanation
Height Correction Model: Wind speed variation with height typically uses the 1/7 power law formula, requiring exponent adjustment based on actual wind conditions. The code should allow parameterization of the exponent for flexibility.
Unit Consistency: Ensure physical unit consistency in input file parameters to avoid calculation errors caused by unit confusion. The script should include unit validation checks.
Result Verification: Recommended to perform visual inspection of generated wind pressure distribution through MATLAB plotting functions (e.g., `plot`, `scatter`) to confirm the pressure gradient along blade span meets expectations.
This method provides fundamental input data for wind turbine blade load calculations, which can subsequently be used for aerodynamic performance analysis or structural strength verification. Based on practical requirements, the approach can be extended to incorporate more complex meteorological conditions such as turbulence intensity and wind direction variations through additional MATLAB modules.
