Transmission lines are one of the vital elements of the Electrical Power System network. It is very unfortunate that, the theoretical concept studied in the classroom about power system does not give the physical insight with practical exposure as actual transmission lines are not readily accessible in the hardware environment. To overcome this problem, a prototype model of transmission lines can be developed and various experimentations of power system could be carried out through it. This would provide practical learning with hands on experience to the students and researchers in the area of Power system. Therefore, in this paper, a scaled down laboratory model of an existing 400 kV long transmission line of the western grid of India has been developed. The novelty of the prototype laboratory model is that being low cost, all the electrical parameters of the transmission line are such designed that they actually resemble the existing transmission line which can be further utilized for fault analysis, steady-state, transient performance of power system, power system protection along-with incorporation of FACTS devices for power system compensation , power management and control. The developed prototype model can be configured with different transmission line lengths and can be analyzed through both “π” and “T ” topologies. The system behaviour of developed prototype laboratory model is validated with the MATLAB simulation and hence this proposed model can be used as a scaled down version of transmission line by the students and researchers for experimentation and research in the field of power system studies.
