| Zusammenfassung: | The invention discloses a direct-drive wind turbine generator side direct-current impedance/admittance modeling method, medium and system. The method comprises the steps that a converter control link small signal model, a PWM link small signal model, a machine side converter power conservation small signal model and a machine side PMSG circuit relation small signal model are established; acquiring converter parameters; through simultaneous conversion of the converter control link small signal model, the PWM link small signal model, the machine-side converter power conservation small signal model and the machine-side PMSG circuit relation small signal model, a direct-drive wind turbine generator set machine-side direct-current impedance/admittance model is established, and a direct-drive wind turbine generator set machine-side direct-current impedance/admittance model is established; and calculating the direct-current impedance and admittance of the machine side of the direct-driven wind turbine generator by a |
