| description | The invention relates to a subsynchronous oscillation suppression method based on additional virtual impedance control. The method comprises the following steps: 1) constructing a hybrid impedance model based on a doubly-fed wind power plant through a VSC-HVDC grid-connected system; and 2) suppressing subsynchronous oscillation through a virtual resistance control mode of reasonably configuring parameters according to the hybrid impedance model and the cascade system characteristic stability criterion. Compared with the prior art, the method has the advantages that the cost problem of additionally arranging the FACTS device is solved, the designed additional virtual impedance controller can restrain the subsynchronous oscillation phenomenon of the multi-alternating-current and direct-current parallel grid-connected system, the subsynchronous stability of the system is improved, and safe and stable operation of new energy power transmission is guaranteed.
