RANCANGAN KEANDALAN SISTEM DISTRIBUSI TENAGA LISTRIK MENGGUNAKAN TOPOLOGI JARINGAN LOOPING PADA GARDU UTAMA BANDAR UDARA HALIM PERDANAKUSUMA

Gardu Utama Bandara Halim Perdanakusuma memperoleh pasokan listrik dari tiga penyulang, yaitu GI Cawang, GI Cipinang dan GI Taman Mini. Namun, sistem distribusi tegangan menengah yang digunakan berkonfigurasi radial sehingga kontinuitas pasokan listrik berpotensi terhenti apabila terjadi gangguan pada satu jalur yang tersedia. Penelitian ini merancang sistem distribusi tenaga listrik menggunakan konfigurasi looping. Metode penelitian yang digunakan penelitian ini adalah Research and Development (R&D) level 1, meliputi pengumpulan data, observasi lapangan, analisis kebutuhan sistem, serta penyusunan Single Line Diagram (SLD), Detail Engineering Design (DED), Bill Of Quantity (BOQ), dan Rencana Kerja dan Syarat (RKS). Hasil perancangan menunjukkan bahwa konfigurasi looping mampu menyediakan jalur suplai alternatif ketika salah satu penyulang ataupun jalur mengalami gangguan. Rancangan menggunakan kabel N2XSEFGbY 3 x 240 mm², kubikel SIEMENS SIMOSEC 20 kV, dan konfigurasi double incoming yang sesuai dengan kebutuhan sistem distribusi. Rancangan ini diharapkan dapat menjadi alternatif untuk meningkatkan keandalan, fleksibilitas operasi dan kontinuitas pasokan listrik.

The Main Substation of Halim Perdanakusuma Airport receives its electrical power supply from three feeders, namely Cawang Substation, Cipinang Substation, and Taman Mini Substation. However, the existing medium-voltage distribution system employs a radial configuration, causing the continuity of the power supply to be vulnerable to interruptions whenever a fault occurs on the available feeder. This study aims to design a looping distribution system to improve the reliability and continuity of the electrical power supply. The research applies the Research and Development (R&D) level 1 method, which includes data collection, field observation, system requirements analysis, and the preparation of a Single Line Diagram (SLD), Detail Engineering Design (DED), Bill Of Quantity (BOQ), and Technical Specifications (RKS). The proposed design demonstrates that the looping configuration provides an alternative power supply path when a feeder or distribution line experiences a fault. The design utilizes N2XSEFGbY 3 x 240 mm² medium-voltage cables, SIEMENS SIMOSEC 20 kV switchgear, and a double incoming configuration that meets the distribution system requirements. Therefore, the proposed design is expected to serve as an alternative solution for improving the reliability, operational flexibility, and continuity of the electrical power supply.
