Abstract

Sistem proteksi yang efektif dalam mengatasi arus hubung singkat sangat penting untuk menjaga keandalan dan ketersediaan sistem tenaga listrik di industri. PT Linde Indonesia adalah perusahaan yang bergerak di bidang industri gas dan teknik pemisahan udara, di mana perusahaan ini mengandalkan sistem tenaga listrik yang andal untuk menjalankan operasionalnya. Permasalahan utama yang dapat mengganggu keandalan sistem kelistrikan perusahaan adalah penambahan beban kebutuhan pasokan listrik, di mana peningkatan beban ini sejalan dengan peningkatan nilai arus hubung singkat hingga melampaui kapasitas peralatan. Salah satu solusi yang bisa diterapkan adalah menggunakan Hybrid Superconducting Fault Current Limiter (Hybrid SFCL), yang membatasi arus gangguan dengan memanfaatkan reaktansi tambahan pada Current Limiter Reactor (CLR). Berbeda dengan reaktor murni, peralatan ini memberikan reaktansi hanya ketika terjadi gangguan, sehingga dapat mempertahankan kualitas daya dan mengurangi tegangan jatuh yang terjadi. Hasil studi menunjukkan bahwa terjadi penurunan arus hubung singkat hingga 34%. Pada switchgear P2.CF1 (B10-F1-RM1) terjadi penurunan dari 45,672 kA menjadi 30,079 kA, sedangkan pada switchgear P2.CF2 (B10-F1-RM1) terjadi penurunan dari 45,674 kA menjadi 29,987 kA. Sehingga switchgear akan tetap aman meskipun terjadi arus gangguan hubung singkat 3 fasa maksimum. Penurunan nilai arus hubung singkat akibat pemasangan Hybrid SFCL dapat mengganggu koordinasi proteksi yang ada sebelumnya. Oleh karena itu, diperlukan studi perencanaan koordinasi proteksi setelah pemasangan Hybrid SFCL. Hasil studi ini diharapkan dapat menjadi dasar untuk merancang dan mengimplementasikan sistem proteksi yang andal, efisien, dan aman di PT Linde Indonesia.

An effective protection system in overcoming short circuit currents is very important to maintain the availability and availability of electrical power systems in industry. PT Linde Indonesia is a company operating in the gas industry and aviation engineering, where this company relies on a reliable electric power system to run its operations. The main problem that can disturb the noise of a company's electrical system is the increase in electricity supply requirements, where this increase in load is in line with an increase in short circuit current values that exceed the capacity of the equipment. One solution that can be implemented is to use a Hybrid Superconducting Fault Current Limiter (Hybrid SFCL), which limits current faults by utilizing additional reactance in the Current Limiter Reactor (CLR). In contrast to pure reactors, this equipment provides reactance only when a disturbance occurs, so that it can maintain power quality and reduce voltage drops that occur. The research results showed that there was a reduction in short circuit current of up to 34%. In switchgear P2.CF1 (B10-F1-RM1) there was a decrease from 45,672 kA to 30,079 kA, while in switchgear P2.CF2 (B10-F1-RM1) there was a decrease from 45,674 kA to 29,987 kA. So the switchgear will remain safe even if a maximum 3-phase short circuit current occurs. The decrease in short circuit current values due to the installation of the Hybrid SFCL can disrupt the coordination of previously existing protection. Therefore, a protection coordination planning study is needed after installing the Hybrid SFCL. It is hoped that the results of this research can be a basis for designing and implementing a reliable, efficient and safe protection system at PT Linde Indonesia.
