Insertion of 275 kV Transmission Line for Improving the Voltage Profile and Efficiency of Electrical Power System

Abstract

The location of electricity generation generally lies in the centers of renewable energy sources which are generally far from urban centers, such as in the province of South Sulawesi, Indonesia. This condition becomes a separate issue related to the quality of the voltage and the efficiency of the electrical system that uses 150 kV transmission lines to transmitted electrical energy from the power plants. Therefore, to avoid waste and lack of quality electricity, it is necessary to insert a new transmission line from these power plants to the city of Makassar. Where the transmission line built is 275 kV transmission line because it increases the voltage profile and is efficient compared to 150 kV transmission line even though the network is added to the bank's capacitor. Therefore, this paper shows the reasons why a 275 kV transmission line was chosen for the improvement of voltage and reduction of power losses in South Sulawesi system.
