A FACTS-Based Power Flow Controller Model for The IEEE SSR First Benchmark Model

This paper describes the development of a detailed mathematical model of a representative study system to examine the impact of FACTS-based closed-loop control of AC power on the damping of sub synchronous torsional modes. The mathematical model is an adaptation of the IEEE first benchmark system for the study of subsynchronous resonance, extended to include a controllable series compensator and power flow controller capable of operating in both the constant power and constant angle modes. The paper briefly considers the influence of each such mode of power flow control on torsional mode damping.
