Design of TCSC for classroom and research applications on an analog model power system

This paper discusses the development of a thyristor controlled series capacitor (TCSC) with closed loop controls for use with the analog model power system (AMPS) at the University of Idaho (UI). An overview of the AMPS is presented. The TCSC circuit and characteristics are discussed in brief. Next the determination of TCSC parameters are discussed. With these parameters the possible modes of operation of TCSC were simulated. Then potential closed loop control schemes were discussed and simulated in ATP. With this background the realization of the TCSC in hardware is discussed. Finally the hardware results are compared with that of simulated results.
