Multiple stabilizer setting in multi-machine power systems by the phase compensation method

The phase compensation method based on the concept of damping torque has been successfully applied for the design of Power System Stabilizers (PSS) in single-machine infinitebus power systems for decades. In this paper, the application of the phase compensation method to the design of multiple FACTS-based stabilizers and PSSs in multi-machine power systems is presented. An example three-machine power system is demonstrated, where a TCSC-based stabilizer and a PSS are successfully designed by the phase compensation method to damp power system oscillations.
