A wind turbine is provided. The wind turbine includes an electric generator, a converter and a control system. The electric generator includes a rotor configured to rotate at different rotation speeds thereby operating at different operation points, and a converter having a rotor side converter and a power consumption system, i.e., grid-side, side converter. The control system includes a current control loop and an inter-harmonic damping control unit arranged in parallel to the current control loop. The inter-harmonic damping control unit damping control unit comprises at least a resonant controller which is dependent on the operation point for tracking and damping the one or more inter harmonic(s) of the wind turbine. A method for damping inter-harmonics is also provided.
