Design and Development of Transient Network Analyzer
[attachment=17031]
Abstract
In this thesis an attempt has been made to simulate a scaled down long transmission line hardware module to study transients. a PSPICE simulated model has also been done. Simulation for an ideal surge and a practical surge for open circuit and surge impedance loading of the line has been done on the transient network analyzer and PSPICE model.
What is TNA
The TNA is designed specially for the real time simulation of transients caused by switching operations like line energisation , fault clearing, etc. It comprises of reduced models of AC systems components permitting simulation of any desired system. The TNA provides the greatest flexibility of modeling because of its low operating interfacing easily with electronic models and computer controls.
