TY - THES PB - Universitas Pendidikan Indonesia TI - PENGGUNAAN GOOSE MESSAGE BERBASIS IEC 61850 PADA SISTEM POLA NON-CASCADE BAY TRAFO 3 GIS KIARACONDONG ID - repoupi144288 N2 - Sistem proteksi tenaga listrik yang cepat dan selektif sangat penting untuk menjaga keandalan operasi Gardu Induk, khususnya pada instalasi vital seperti Trafo 3 GIS Kiaracondong. Salah satu kelemahan sistem proteksi konvensional adalah keterlambatan koordinasi antar perangkat. Penelitian ini bertujuan menganalisis penerapan GOOSE Message berbasis standar IEC 61850 dengan pola proteksi non-cascade, yang memungkinkan komunikasi langsung antar relay tanpa perantara pemutus upstream. Metode penelitian dilakukan melalui pengujian dua unit relay fisik yang dikonfigurasi sebagai publisher dan subscriber GOOSE. Tahapan meliputi konfigurasi alamat IP, pembuatan data GOOSE, penetapan setting relay, dan pemrograman logika proteksi. Pengujian dilakukan dengan penyuntikan arus gangguan pada sisi penyulang dan busbar. Hasil menunjukkan bahwa sistem berhasil merespons gangguan secara cepat dan tepat, dengan waktu kerja relay berkisar 0,14?0,78 detik saat komunikasi GOOSE aktif. Selain itu, penerapan logika proteksi non-cascade terbukti mampu mengurangi keterlambatan koordinasi dan memberikan dukungan trip cadangan ketika gangguan tidak ditangani oleh relay penyulang.

A fast and selective power system protection scheme is essential to maintain the reliability of substation operations, especially in critical installations such as Transformer 3 at GIS Kiaracondong. One drawback of conventional protection systems is the delay in coordination between devices. This study aims to analyze the implementation of the IEC 61850-based GOOSE Message using a non-cascade protection scheme, which enables direct communication between relays without upstream circuit breaker intervention. The research was conducted through testing two physical relays configured as GOOSE publisher and subscriber. The procedure included IP address configuration, GOOSE data creation, relay setting adjustments, and protection logic programming. Testing was carried out by injecting fault currents into the feeder and busbar sides. The results showed that the system successfully responded to faults quickly and accurately, with relay operating times ranging from 0.14 to 0.78 seconds when GOOSE communication was active. Furthermore, the non-cascade protection logic proved effective in reducing coordination delays and providing backup tripping when the feeder relay failed to clear the fault.
