METHOD AND SYSTEM OF SUBSYNCHRONOUS OSCILLATIONS AND INTERACTIONS DAMPING

摘要

A method and system of subsynchronous oscillations and interactions damping integrated in in a rotor converter (100) based on an adaptive state feedback controller (132) with two spinning vectors, and a Kalman filter (131) whose parameters are optimized by minimizing maximum sensitivity under a constraint of positive damping for a plurality of sensible scenarios. The damping signal (210) generated by the damping module (130) is applied either to a power proportional integer controller (110) or to a current proportional integer controller (120).
