Design and Analysis of Three-phase 230 kV Transmission Line in the North-East of Myanmar

Abstract

Long transmission lines are required to transmit power from hydroelectric power stations to the places of load, as the sites of water power would be far away from the load centers. In this paper, it designed and analyzed three-phase 230 kV transmission line for the North-East of Myanmar. Shweli hydroelectric power station generates the power of 90 MW for Shweli-Mandalay (Shwe Sar Yan) transmission line portion. The length of the transmission line from Shweli to Shwe Sar Yan is 287.93 km. It aims to distribute electricity to Lashio and Kyaukme districts, Northern Shan State and to transport electricity to Mandalay (Shwe Sar Yan) by using 230 kV Twin Bundle Double Circuit transmission line. The purpose of this paper is to transmit optimum power at a given power factor, over a given distance and regulation, efficiency and losses
