【 摘 要 】

In transmission system named 'Subsistem Bandung Selatan dan New Ujungberung' there are the voltage drop which relatively high and the voltage profile at the receiving ends below 0.95 p.u. Therefore, this research proposed a method to improve the voltage profile in the transmission system using one of Flexible Alternating Current Transmission System (FACTS) technology which is Static Var Compensator (SVC) and 'Subsistem Bandung Selatan and New Ujungberung' as the object. This research aims to get the voltage profile in 'Subsistem Bandung Selatan dan New Ujungberung' before and after connected to SVC and to set optimal location and rating of SVC to maintain the voltage profile at the system that has desire range (0.95 p.u - 1.05 p.u). To get the result in accordance with these objects, Newton -Raphson power flow solution is applied to the system. The result of Newton- Raphson power flow solution of the system shows the voltage profile before connecting to SVC are averagely 140.95 kV or 0.94 p.u while after connecting to SVC are 145.28 kV or 0.97 p.u. The SVC installation is connected to 'Bandung Utara I' as the weakest bus, and the SVC rating is -250 Mvar to 300 Mvar.
