Suppression of Secondary Arc Current in Extra High Voltage 765 KV Transmission Line of 4 Bus System

Avinash Sharma ^[2] | Arti Bhandakkar ^[3]

Abstract: The effectiveness of single-pole auto reclosure (SPAR) in maintaining power system stability is largely determined by the speed with which secondary arc extinction, and hence auto reclosure, can be achieved. In this work there is approach to measure the suppression of secondary arc current by Neutral reactor (shunt reactor) which is applied widely in many countries. In this paper the different results of healthy 4 Bus system, faulted system, Breakers operation without Neutral reactor are compared with the Neutral reactor and Simulation studies were carried out in the MATLAB simulation environment to observe the secondary arc current suppression is achieved by the Neutral reactor is better as compared to without neutral reactor. For the simulation purpose, the model of two-machine 4-bus system with healthy operation, faulted system operation, breaker operation without Neutral Reactor and with Neutral Reactor operation is developed in MATLAB/SIMULINK using Simpower System (SPS) blockset.
