| Abstract: | An overall dynamic model for variable speed brushless doubly-fed machine, including the wind speed, wind-turbine and control system of wind machine, is established. Based on the mathematic model, a variable-speed constant-frequency brushless doubly-fed generator (BDFG) simulation model is built by using SIMULINK of the MATLAB. Then taking examples for ramp change of wind speed and random change of wind speed, the dynamic characteristics of BDFG is simulated. The results show the model is correct; BDFG has good running characteristics and provide a credible foundation for further study on wind power system. |
