FACTS-based stabilizer designed by the phase compensation method. I. Single-machine infinite-bus power systems. II. Multi-machine power systems

In part I of this paper, based on the extended Phillips-Heffron model of a single-machine infinite-bus power system installed with a FACTS-based stabilizer, the conventional frequency-domain phase compensation method is applied to design the FACTS-based stabilizer. Three types of FACTS-based stabilizers, the SVC-based, TCPS-based and TCSC-based stabilizer, are investigated. Examples of successful applications are presented. In part II the frequency domain phase compensation method´s application in multi-machine power systems to design FACTS-based stabilizers is presented. An example of three-machine power system is demonstrated, where a TCSC-based stabilizer is successfully designed by the phase compensation method to damp system oscillations
