A dynamic model representing a Type 4 wind turbine which uses either synchronous generators (SG) or asynchronous generators (AG). Some type 4 wind turbines use direct drive synchronous generators, and therefore have no gearbox.<br/>There are two type 4 models as follows:<br/><ul>
<li>Type 4A: a model neglecting the aerodynamic and mechanical parts and thus not simulating any power oscillations </li><li>Type 4B: a model including a 2-mass mechanical model to replicate the power oscillations but assuming constant aerodynamic torque </li></ul>
<br/>The standard interconnections for the two models are shown in the figure.<br/><br/>Reference: IEC Standard 61400-27-1 Section 5.5.5.<br/>
