Abstract: “The main goal of this study is to improve the voltage at Khartoum Local Market 110kV substation as one of substations of Khartoum Ring Network. Static VA R Compensator has been used to contribute to the improvement of the decline in the voltage at the substation resulting from the different operating conditions. ETAP software has been used in the analysis to determine the effectiveness of this technique in the improvement process. The results obtained were satisfactory and as expected.”

Keywords: Voltage level improvement, Static VAR compensator, Reduction of system losses, ETAP software.
