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.

The invention provides methods and systems for real-time monitoring of the insulation state of wind-powered generator windings comprising the following steps: a) capturing in real-time, during a predetermined time period (in situations where the generator is synchronized to the electrical network but is not yet couplet thereto as well as in situations where the generator is producing energy) the values of one or more electrical and vibration variables of the generator; b) obtaining in real-time, the temporal evolution of the vibration and of the inverse components of electrical variables at one or more predetermined frequencies; c) identifying a possible generator insulation fault when the inverse component of at least one electrical variable and/or one vibration at a predetermined frequency exceeds an absolute threshold or a temporal increase threshold pre-sets.
