IMPLEMENTATION OF ON-LOAD TAP CHANGER IN POWER SYSTEM
Hemanth Kumar
Abstract
This paper studies the effects of on-load tap changer in power systems. Implementation of tap changer
in power systems is very essential to maintain voltage profile. In general, tap changer transformer is
applied at load buses which are prone to voltage stability. To implement these transformers, the power
flow Jacobian matrix elements should be changed suitably. This paper main consideration is the
changing of Jacobian matrix elements in Newton Raphson power flow analysis
