The invention relates to a network side control strategy for inhibiting direct-driven wind power subsynchronous oscillation. The strategy comprises steps that step 1, in a network side control loop, a d-axis component Ud of an inverter trigger voltage is acquired through measurement; step 2, the Ud is filtered to acquire a subsynchronous component Udsub of the Ud; step 3, phase compensation is carried out according to time delay of the voltage subsynchronous component during filtering to acquire Usub; and step 4, a PI controller is established, the Usub is fed forward to a comparison link of a voltage outer ring, the Usub, a DC capacitance voltage Udc and a DC reference voltage Uref are taken as input variables of the outer ring PI controller, and network side loop control is realized. The strategy is advantaged in that subsynchronous oscillation inhibition is realized, extra equipment and complex control links are not needed, simple and economic property is realized, moreover, oscillation of each subsynchronous frequency range can be inhibited, general applicability is realized, and normal operation of a direct-driven wind power grid connected is not influenced.
