| description | The invention discloses a subsynchronous oscillation suppression method, system and device. The method comprises the following steps: extracting a power angle deviation signal of a doubly-fed induction wind generator; according to a power angle deviation signal of the doubly-fed induction wind generator, modulating to generate a subsynchronous component signal of power angle deviation; and superposing the power angle deviation subsynchronous component signal to the voltage of a q-axis control loop on the rotor side of the doubly-fed wind generator for performing compensation control on the q-axis voltage of the rotor and suppressing subsynchronous oscillation. According to the invention, subsynchronous oscillation caused by grid connection of the doubly-fed wind power plant through a series compensation line can be effectively suppressed, and the stability of a power system is ensured.
