Abstract
This paper discussed about the influence of Static VAR Compensator (SVC) in transmission system 150 kV, Sumbagut region. Transmission system and SVC parameters in this study is simulated by using computer. Purpose of simulation was to show voltage profile of the system before and after installed SVC. Based on simulation for the condition before installed SVC, there were four Buses; Aek Kanopan, Kuala Tanjung, Kisaran and Rantau Prapat which have critical voltages sequentially 89,92%; 89,92%; 89,97%; and 89,96%. After installed SVC, voltage profile of the busses increased sequentially 91,7%; 91,74%; 91,7%; dan 91,73%. Based on simulation result, SVC improved voltage profiles in transmission system.

Abstrak—Studi ini membahas tentang pengaruh pemasangan Static VAR Compensator (SVC) pada sistem transmisi tenaga listrik 150 kV Sumbagut. Metode yang digunakan dalam studi ini adalah simulasi menggunakan komputer dan perhitungan untuk mendapatkan parameter-parameter SVC yang akan disimulasikan. Simulasi dilakukan untuk melihat profil tegangan pada sistem sebelum dan sesudah dipasang SVC. Dari hasil simulasi sebelum pemasangan SVC diperoleh data Bus yang memiliki tegangan kritis atau dibawah standar. Bus yang mengalami tegangan yang dibawah standar atau kritis adalah Bus Aek Kanopan, Kuala Tanjung, Kisaran dan Rantau Parapat. Besar tegangan masing-masing Bus berturut-turut 89,92%; 89,92%; 89,97%; dan 89,96%. Setelah pemasangan SVC nilai tegangan pada Bus berubah menjadi 91,7%; 91,74%; 91,7%; dan 91,73%. Dari hasil simulasi dapat dilihat bahwa pemasangan SVC berdampak pada perbaikan profil tegangan sistem transmisi.
