Wind Turbine Driveline with Vibrations in Simscape™

Version 2.0 for MATLAB® R2023a or newer

Introduction

This example includes a wind turbine rotor and driveshaft with optional transverse vibrations in Simscape Driveline™ and controllers in Simulink®. A live script describes the model components and demonstrates workflows for analyzing the system performance.

The direct-drive wind turbine has a power capacity of 10 MW. Controllers based on the NREL 5-MW reference wind turbine adjust the generator torque and collective blade pitch.

The rotor and shaft are supported by 4 fluid film bearings. This example lets you optionally model transverse vibrations of the driveshaft due to a generator unbalanced magnetic force. The rotor dynamics can be modeled using a lumped mass finite element method or a reduced order model to simulate the shaft vibrations efficiently. The reduced order model can be a traditional static eigenmodes method, a speed-dependent eigenmodes method, or a Craig-Bampton method.
