Systems and methods for controlling torsional oscillation in wound field synchronous generator machines

摘要

A method for controlling torsional oscillation includes detecting angular position of a wound field synchronous generator machine (100; 200), extracting information indicative of torsional oscillation, selecting synchronous torsional oscillations, compensating for the synchronous torsional oscillations with an exciter signal, and controlling field current in the wound field synchronous generator using the exciter signal. A damping controller (136; 236) includes a damping module (10) with a synchronous selective compensator (11) and a synchronous notch filter for generating torsional oscillation compensation signals for asynchronous torsional oscillation.
