Abstract: Doubly-fed wind turbine is easy to produce sub-synchronous oscillation in series compensation grid.Using virtual synchronous control structure to improve inertia and damping for grid may also lead to subsynchronous oscillation risk. In view of the causes of sub-synchronous oscillation,firstly,the double-fe...
