| Abstract: | The transfer function model of the small signal disturbance components of the system is de-duced in detail by analyzing the wind power generation unit model in the distributed power supply system, and then the small signal control model and the output impedance expression of wind power unit in d and q axis are obtained respectively. In the frequency domain,the output impedance is simulated and ana-lyzed in different bus voltage,flux linkage and filter capacitor. The simulation results are of certain refer-ence value for the parameter design of the system. |
