Abstract

The paper presents a study on the application of static phase shifters to stabilize common-mode torsional oscillations in the IEEE Second Benchmark Model, system-2. In order to effectively suppress the unstable torsional modes, a unified approach based on modal control theory is proposed and a set of static phase shifter controllers (SPSC) are designed. The effectiveness of the proposed damping scheme is demonstrated by using the frequency-domain approach based on eigenvalue analyses and the time-domain approach based on dynamic response simulations.<>
