| Abstract: | The basic structure of variable speed constant frequency(VSCF) double-fed wind turbine unit is presented and the dynamic mathematical model of VSCF double-fed wind generator unit in d-q coordinate system is established.By use of Matlab/Simulink the simulation modules for VSCF double-fed wind turbine unit are set up and the dynamic stability of double-fed wind generator connected into power grid is simulated.Simulation results show that the established model is correct.The utilization rate of wind energy can be greatly heightened by applying variable speed technology to wind power generation system and power system stability can also be improved.Variable speed double-fed wind turbine unit have function of low voltage ride through(LVRT). |
