Abstract

The series compensation has the potential to produce the modes associated with the turbo-generators electrical torque. The influence of the load added to the problem of SSR in the transmission system, can cause problems of instability subsynchronous torsional interactions (SSTI). In this work, it is proposed a new monitoring technique through the torsional behavior modes forms based on a spectral analysis of the electrical subsynchronous torque component to detect its associated frequencies and to establish the coincidence with the mechanical turbo-generator torsional oscillation subsynchronous frequencies, transient load model is included indicating results of utmost importance in their damping modes.
