Introduction to Sub-synchronous Resonance
CHAPTER OUTLINE
In this chapter, the subsynchronous resonance (SSR) that occurs in a fixed series capacitor (FSC)-compensated transmission line connected to a steam turbine-generator power system is illustrated by means of a tutorial example to enhance the understanding of SSR. When such an event takes place, it triggers large amplitude oscillations of the rotor shaft system below the fundamental frequency. If this occurs repeatedly, the shaft system is subject to severe strain and fatigue, leading to damage of the mechanical systems.
Here, the occurrence of such a phenomenon is explained in steps, considering a simplified model ...
