In the early 1990s, Western Area Power Administration (WAPA) installed a TCSC device at its Kayenta substation in northeastern Arizona. Analysis, field testing, and early experience have proven the validity of the TCSC design concept as well as the ability to model and control the device within certain parameters. However, a great deal was still unknown about the TCSC, such as its behavior at frequencies other than 60 Hz. Such knowledge would be useful in assessing the TCSC`s potential for specific power system control functions, such as power oscillations and subsynchronous resonance (SSR) damping. Researchers needed to develop new models capable of analyzing the device and its responses at these frequencies. Optimal use of Flexible AC Transmission System (FACTS) devices requires enhanced control capabilities and understanding of complex behaviors. This report describes the development of analytical models to more accurately study and operate the Thyristor Controlled Series Compensation (TCSC) device.
