MATLAB Simulink Simulation Model for Wind Power Generation System

This document presents a MATLAB Simulink simulation model for wind power generation systems, specifically developed to analyze the response characteristics of induction generators under varying wind speed conditions. The simulation architecture incorporates critical components such as wind turbine models using aerodynamic equations, power converters with PWM control strategies, and induction machine dynamics simulated through d-q transformation techniques. We will provide a detailed breakdown of the model construction process, covering parameter configuration for wind profiles, machine specifications, and control system tuning. The implementation includes MATLAB function blocks for calculating turbine power coefficients and S-function blocks for custom control algorithms. Furthermore, the analysis explores performance variations of induction generators across different wind speed scenarios, examining metrics like torque ripple, power quality, and grid synchronization stability. The simulation employs step-change wind inputs and turbulence models to assess transient responses and steady-state behavior. Through these simulations, engineers can gain deeper insights into wind power system operations and obtain quantitative data for performance optimization, including pitch control tuning and maximum power point tracking (MPPT) algorithm refinement. The model serves as a practical tool for validating control strategies and predicting system behavior under real-world operating conditions.
