Modern flexible AC transmission system (FACTS) devices

K. Wang and M.L. Crow,     Missouri University of Science Technology, USA


This chapter describes the primary modern FACTS devices currently deployed worldwide. Modern FACTS devices are based on the concept of the voltage source converter (VSC) to inject a controllable AC waveform at the fundamental frequency into the power system to alter the power flow at a bus or across a transmission line. This chapter reviews the three primary modern FACTS devices: the static synchronous compensator (STATCOM), the static synchronous series compensator (SSSC), and the unified power flow controller (UPFC). The state-space nonlinear model is provided for each device as well as a typical control ...
