Abstract

Optimalisasi Pemasangan Thyristor Controlled Series Capacitor (TCSC) Pada Subsistem Paiton – Grati 150 kV Untuk Meningkatkan Efisiensi Pengiriman Daya Listrik Menggunakan Genetic Algorithm (GA) Rifqi Rizaldy Abraham Lomi rifqirizaldy23@gmail.com ABSTRAK Meningkatkannya kebutuhan daya listrik membuat masalah rugirugi daya dianggap menjadi serius sehingga diperlukan solusi cepat untuk mengatasinya. Saat ini hanya terdapat satu opsi yaitu menggunakan peralatan FACTS (flexible alternating current transmission system). Peralatan ini sudah terbukti ampuh dalam menyelesaikan problematika rugi-rugi daya dan perbaikan profil tegangan di berbagai negara. Di Indonesia sendiri, sebelumnya sebuah peralatan FACTS, berupa SVC (static var compensator) sudah dipakai pada sistem transmsisi jawa timur dan bali, lebih tepatnya pada subsistem Paiton-Grati. Namun, hanya dalam beberapa tahun peralatan tersebut tidak beroperasi lagi / rusak akibat penggunaan yang berlebihan tanpa diiringi dengan perawatan yang baik. Akibat dari hal ini, PT. PLN (Persero) selaku pengelola sistem kelistrikan mengalami kesulitan dalam menekan rugi-rugi daya pada subsistem Paiton-Grati. Jadi, melalui penelitian ini penulis menyarankan untuk menggunakan TCSC (thyristor controlled series capacitor) sebagai pengganti SVC yang rusak. Sedangkan dalam menentukan titik pemasangannya digunakanlah GA (genetic algorithm). Berdasarkan simulasi yang dilakukan, titik optimal pemasangan TCSC ialah bus Gondang Wetan dan rugi-rugi daya listrik dapat direduksi dari 142,713 MW menjadi 93,24 MW (daya aktif) dan dari 47,41 MVAR menjadi 21,57 MVAR (daya reaktif). Kata Kunci - FACTS, TCSC, GA, Paiton-Grati iii Optimal Placement of Thyristor Controlled Series Capacitor (TCSC) on Paiton – Grati Subsystem 150 kV to Increase Power Transfer Efficiency Using Genetic Algorithm (GA) Rifqi Rizaldy Abraham Lomi rifqirizaldy23@gmail.com ABSTRACT The Increasingdemand of electricity in every years has made power losses phenomenon become serious problem. So it must be taking care of immediately. Right now, the only quickest way to reduce power losses is by using FACTS (Flexible Alternating Current Transmission System) Device. This Device has been prove effective to minimalize power losses and maintain voltage stability in various country. In indonesia itself, previously an FACTS equipment, in the form of SVC (static var compensator) has been used in east java and bali transmission system, more precisely Paiton – Grati Subsystem. However, in just a few years the equipment is no longer operate due to excessive use without proper care. As a result, PT. PLN (Persero) as the electricity system manager has difficulty in suppressing power losses in the PaitonGrati subsystem. So, through this research the authors recommend using TCSC (thyristor controlled series capacitors) as a replacement for a damaged SVC. Whereas in determining the point of installation, GA (genetic algorithm) is used. Based on the simulation, the optimum point of installation of TCSC is Gondang Wetan bus and electric power losses can be reduced from 142.713 MW to 93.24 MW (active power) and from 47.41 MVAR to 21.57 MVAR (reactive power).
