Abstract

IMPLEMENTASI STATCOM UNTUK MENINGKATKAN KESTABILAN TEGANGAN PADA SISTEM 150KV PT.PLN SULSELBAR (SULAWESI SELATAN DAN BARAT) Fuad Ditya, Awan Uji Krismanto fuadditya27@gmail.com ABSTRAK Kestabilan sistem tenaga listrik adalah kemampuan sistem untuk mempertahankan kondisi stabil setelah di hadapkan pada ganguan. Kestabilan tegangan adalah suatu kemampuan dari sistem tenaga untuk mempertahankan nilai tegangan terhadap ganguan-ganguan di sistem tenaga. Sistem PT PLN Sulselbar merupakan sistem kelistrikan yang menghubungkan beberapa pembangkit dan beban seiring meningkatnya populasi penduduk sehingga akan miningkatkan permintaan daya pada sistem. . Penggunaan kapasitor dapat membantu meningkatkan profil tegangan,akan tetapi sifat kapasitor yang tidak fleksibel atau memiliki nilai yang fix sehingga dapat berpotensi menyebabkan overvoltage, permasalahan tersebut dapat di atasi dengan penggunaan Diantara perangkat FACTS, static compensator dilihat yang paling memadai karena dapat memasuk daya reaktif yang dibutuhkan, untuk memperbaiki perubahan tegangan yang bermasalah dan meningkatkan stabilitas sistem. STATCOM dikategorikan sebagai teknologi dalam bidang kompensator daya reaktif. STATCOM mempunyai kelebiham yaitu menghasilkan nilai harmonic yang kecil dan nilai tegangan AC yang terkendali sebagai outputnya karena STATCOM memiliki kemampuan menyalurkan daya reaktif induktif dan reaktif kapasitif sehingga tidak terjadi kenaikan atau penerunan tegangan saat terjadi kenaikan beban dan pelepasan beban. Pada penelitian ini dilakukan analisis kestabilan tegangan statis dan analisis kestabilan tegangan dinamis dan di dapatkan hasil bahwa statcom dapat meningkatkan kestabilan tegangan dan mampu mempertahankan nilai tegangan pada batas normal lebih baik di bandingkan kapasitor. Kata kunci = Stabilitas Tegangan ,Analisis Statis, Analisis Dinamis dan STATCOM iii STATCOM IMPLEMENTATION TO IMPROVE VOLTAGE STABILITY IN 150KV PT. SULSELBAR SYSTEMS (SOUTH AND WEST SULAWESI) Fuad Ditya, Awan Uji Krismanto fuadditya27@gmail.com ABSTRACT The stability of the electric power system is the ability of the system to maintain stable conditions after being faced with interference. Voltage stability is an ability of the power system to maintain the voltage value against disturbances in the power system. The PT PLN Sulselbar system is an electrical system that connects several power plants and loads along with the increasing population so that it will increase the power demand on the system. . The use of Capasitor can help increase the voltage profile, but the nature of the capasitor is inflexible or has a fix value so that it can potentially cause overvoltage, these problems can be overcome with use Among FACTS devices, the static compensator is seen to be the most adequate because it can enter the reactive power needed , to improve voltage changes that are problematic and improve system stability. STATCOM is categorized as a technology in the field of reactive power compensators. STATCOM has the advantage of producing small harmonic values and controlled AC voltage values as its output because STATCOM has the ability to channel inductive and reactive capacitive reactive power so that there is no increase or transmission of voltage when load increases and load is released. In this study an analysis of static voltage stability and dynamic voltage stability analysis and obtained results that statcom can increase the stability of the voltage and be able to maintain the voltage value at the normal limit better than the capacitor. Keywords = voltage stability, static analysis, dynamic analysis and STATCOM
