Rotor Oscillation Modes and Excitation Control

This lecture covers the rotor angle modes with manual excitation control, discussing the damping ratios and frequencies associated with different types of excitation control. It analyzes the effects of excitation control on rotor oscillation modes, highlighting the impact of power system stabilizers on the stability of intermachine and local modes. The lecture also explores the participation factors of a synchronous generator connected to an infinite node, presenting the configuration and dominant states. Additionally, it delves into the mode shapes derived from eigenvectors associated with the rotor of the generator. The instructor explains the dynamic equations of the power system and the implications of isochronous regulation and setpoint modifications on system stability.
