A dynamic model representing a type 3 wind generator and its related standard equipment models is associated with a dispersed generator in the static (power flow) model and has the standard interconnection shown above.<br /></p><p><br /></p><p>A type 3 wind turbines uses a WRAG, where the stator is directly connected to the grid and the rotor is connected through a back-to-back power converter. Besides the generator side converter (GSC) and line side converter (LSC), it may use a crowbar (CB) to protect the GSC during grid faults, and / or a chopper (CH) to balance the aerodynamic power produced during the grid fault.<br /></p><p><br /></p><p>The losses in the generator system are neglected using the wind turbine terminal power <i>p</i>WTT as input to the generator air gap power <i>p</i>ag input to the mechanical model.<br /></p><p><br /></p><p>More information is contained in IEC Standard 61400-27-1 Section 6.4.3.<br /></p>
