| Abstract: | The small-signal models for DFIG include the rotating system model,stator model,controller model and the grid model;a three-mass model is used to model the rotating system which contains blades,high-speed shaft,gear box,low-speed shaft and the rotor of the generator.The stator and the grid model are established in the dq coordinate system.The equations of state of the whole model are derived.The simulation software EMTP is applied to establish the stand-alone to infinity system for the study of wind turbine torsional vibration.In the simulation,three-phase ground fault is applied to excite the torsional vibration.The simulation results show that the torsional interaction occurred and the torsional vibration frequency agrees with the natural frequency of the rotating shaft system,and therefore verify the accuracy of the models. |
