Transmission line efficiency enhancement with inclusion of smart wires and controllable network transformers

Abstract

Transmission line efficiency is one of the major issues to be addressed in the heavily stressed electrical power system. It is a challenge to improve the overall power transfer capability along with considering system constraints that influences the better operational outcome of the power system at minimal cost of expansion. This problem can be overcome by having controllable power flow between tielines. This paper increment transmission line efficiency issueby installation of SmartWire Modules (SWM)and Controllable Network Transformers (CNT)in the transmission line when it is over loaded. Smart wire is a single turn transformer device which can improve the transmission capacity of transmission lines. Whereascontrollable network transformer is a smart transformer device connected in between the tie lines to provide more accurate power flow control.
