Abstract: Subsynchronous resonance (SSR) occurs in a series-capacitor-compensated power system when a mechanical mass-spring mode coincides with that of the electrical system. In this thesis, a complete high order model including mass-spring system, series-capacitor-compensated transmission line, synchronous generator, turbines and governors, exciter and voltage regulator is derived. Eigenvalue analysis is used to find the effect of capacitor compensation, conventional lead-lag stabilizer, loading and dampers on SSR. Finally, controllers are designed to stabilize multi-mode subsynchronous resonance simultaneously over a wide range of capacitor compensation.
