Abstract
As the increasing of installed capability of wind power in power system, the dynamic wind turbine models are required for wind turbine and wind farm stability assessment. For this reason, the wind turbine models have to be simulated accurately compare to the wind turbine operation behavior especially during grid fault. An accurate DFIG wind turbine dynamic model is presented. For low voltage ride through (LVRT) simulation, the 5th and 3th order generator model, including converter with crowbar and chopper, pitch angle controller, drive train model are analyzed. Simulations are carried out to analyze the model structure and parameters influence to LVRT behavior. The models are simulated, and validated with the wind turbine LVRT field-test data. Validation results show the accuracy of the model.
