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.
