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.

Inter-harmonic damping system and method

A wind turbine control system and method, for the type of wind turbines includes a rotor, an asynchronous generator driven by the rotor and configured for providing an active power to a grid, and a power converter connected to the generator and configured to interact with the generator for generating the required active power for the grid. The control system includes a converter control unit for controlling the power converter and for estimating a frequency derivative of the frequency of the grid, and a wind turbine controller configured for receiving the estimated frequency derivative and for considering the received frequency derivative for determining a synthetic inertia. The converter control unit controls the power converter to cause the generator to also provide the synthetic inertia, in the form of active power.

Wind turbine control system and method

A method and system of subsynchronous oscillations and interactions damping integrated in in a rotor converter based on an adaptive state feedback controller with two spinning vectors, and a Kalman filter whose parameters are optimized by minimizing maximum sensitivity under a constraint of positive damping for a plurality of sensible scenarios is provided. The damping signal generated by the damping module is applied either to a power proportional integer controller or to a current proportional integer controller.
