Feed-forward control method and device of grid-connected inverter, medium and wind generating set

The invention provides a feed-forward control method and device of a grid-connected inverter, a medium and a wind generating set. The feed-forward control method can comprise the steps that first voltage is obtained based on capacitance voltage of a capacitor in a filter connected with the output end of the grid-connected inverter; obtaining a second voltage by filtering the capacitor voltage; multiplying the first voltage by a first weighting coefficient to obtain a first weighted voltage; multiplying the second voltage by a second weighting coefficient to obtain a second weighted voltage; adding the first weighted voltage and the second weighted voltage to obtain a feed-forward voltage control component; and controlling the grid-connected inverter based on the feed-forward voltage control component. According to the feed-forward control method and the feed-forward control device of the grid-connected inverter, the current harmonic wave of the grid-connected point can be reduced, and the phase angle stabilit
