In the electrical engineering stream, the aspects of power system analysis and operation and control are imparted both in UG and PG level. As part of the course, students learn the load flow analysis, fault calculation. Most of the experiments are carried out with the software simulation. However the student cannot visualize the various voltage levels of operation, the losses and the limitation on the physical distances involved in transmission power through long distances. In this connection, it is envisaged to develop an actual miniature model of the transmission line simulator.

Transmission Line Simulator is a sophisticated module developed with the purpose of helping students in their understanding of some basic ideas in power systems. The simulation will also help the students to demonstrate the effects of different parameters on the power system with easier experiments.

Highlights

• 110 V, 3 Phase station model
• Auto transformer in the station side for voltage control
• Energy meter in both station and load models to measure the voltage, current, power, power factor, etc
• Transmission line model as 18 pi circuits, consisting of series inductor, series resistor and shunt capacitor (Values can be varied as per the experiment)
• Series capacitor model to vary the series compensation from 10% to 50%
• Autotransformer for voltage control in the loading section
• Inductive and resistive load.
• Capacitor bank to improve on the power factor.
• Upto 400Km transmission line length can be achieved using the simulator.
