"One of the most promising network controllers for the bulk power system is the family of power electronics-based controllers, known as "flexible AC transmission system" (FACTS) devices. FACTS devices work by modifying power flow in individual lines of the power grid, maintaining voltage stability, and damping oscillations. The rapid development of the power electronics industry has made FACTS devices increasingly attractive for utility deployment due to their flexibility and ability to effectively control power system dynamics. The primary function of the FACTS is to control the transmission line power flow; the secondary functions of the FACTS can be voltage control, transient stability improvement and oscillation damping.
Although considerable FACTS research work has concentrated on developing control strategies via simulation, there is a general lack of experimental verification of many of the proposed controls. In order to fully understand how to effectively incorporate FACTS devices into existing power systems, a hardware prototype for verification is necessary in addition to software simulation. Experimental studies provide valuable data to evaluate models, test proposed control algorithms, and analyze dynamic performance. Furthermore, experimental studies provide the basis with which to predict the device performance in the actual power system operation.
Traditional software-based simulation has the disadvantage of being unable to exactly replicate real operational conditions. On the other hand, a small laboratory power system is not capable of fully capturing the depth and breadth of large-scale power system dynamics. One way to bridge the gap between simulation and real conditions is to combine real-time simulation (RTS) and hardware-in-the-loop (HIL). The contribution of this work is the development of the hardware-software co-design process required to successfully implement the FIL
The FIL development has been a joint electrical engineering and computer science project funded by the National Science Foundation and Sandia National Laboratories. This dissertation details the FIL-HIL development from the hardware perspective."--Abstract, pages iii-iv.
