DLR EWITAC LIBRARY

The DLR EWITAC Library for wind turbines gives you a jump-start for modeling Wind Turbines with Modelica®. It contains complete turbine models, including all relevant components such as flexible rotor blades, flexible tower structures, standard control blocks and power electronic models for net- integration. Models for the environment enable you to play through scenarios such as gust load alleviation or a low-voltage-ride-through for grid code compliance. The library is commercially available at LTX.   

FEATURES OF THE LIBRARY

  • Rotor aerodynamics
