Design, Analysis, Fabrication, and Testing of Laboratory Model of Transmission Line

摘要

This article presents a procedure for the development of a scaled-down laboratory model of a transmission line based on per unit, values of a true line. The X/R ratio of the model is kept same as that of the true line, as then only their performance can be compared. The current-carrying capacity of the scaled-down model is closer to 20 A to enhance its utility with different flexible AC transmission systems devices. A scaled-down model of a true line for which parameters are available in the open literature is fabricated, and a case study of its simulation and validation is presented. These studies show that the laboratory model is able to emulate closely the true line, and therefore, it can be fruitfully used for the dynamic study of the transmission line embedded with flexible AC transmission systems and hardware-in-loop simulation studies.
