Abstract

Electric power is one of energy resource which is very important for human life sustainability. The Electric power reliability is top priority in electricity distribution system from the power plant to the consumer. Switchyard/Substation is one of electricity distribution sub-system from high-voltage to low-voltage. Busbar is main component in Substation/Switchyard that served as intersection of others equipment to receive and distribute the energy. To meet Switchyard/Substation system reliability, each installation has protection system from disturbances that arise both system and non-system disorders. Relay Protection work based on relay differential’s principle which is comparing input and output currents for CT1 to CT2. GISTET 500 kV Durikosambi utilized double system busbar with one and half Circuit Breaker (3 CB) configuration. GISTET 500 kV Durikosambi’s Disturbance occurs during IBT 2 voltage-distribution maneuver that connected to 500/150kV system load. Disturbance has been detected phase to ground that effect busbar differential relay works. Based on analysis, Busbar Differential Relay work due to an unbalanced current reading that effect Busbar A trip which connected to IBT 2. Keywords : Busbar, Differential Relay, GISTET 500 kV Durikosambi. Tenaga listrik merupakan salah satu sumber energi yang sangat penting untuk kelangsungan hidup manusia. Keandalan sistem tenaga listrik akan menjadi prioritas utama dalam sistem penyaluran tenaga listrik dari pembangkit menuju konsumen. Gardu induk merupakan salah satu sub sistem penyaluran tenaga listrik dari tegangan ekstra tinggi menuju tegangan rendah yang kemudian disalurkan ke konsumen. Busbar merupakan bagian utama pada instalasi di Gardu Induk yang berfungsi sebagai titik pertemuan peralatan-peralatan listrik lainnya untuk menerima dan menyalurkan tenaga listrik atau daya listrik. Untuk memenuhi keandalan sistem pada Gardu Induk, tentunya pada busbar memiliki pengaman atau sistem proteksi dari gangguan. Rele proteksi busbar bekerja berdasarkan prinsip rele differential dimana membandingkan arus yang masuk dan arus keluar pada CT1 terhadap CT2. Di GISTET 500 kV Durikosambi menggunakan sistem double busbar dengan konfigurasi satu setengah PMT (3 PMT). Gangguan pada GISTET 500 kV Durikosambi terjadi pada saat manuver pemberian tegangan IBT 2 yang terhubung dengan beban sistem 500/150 kV. Gangguan terbaca fasa ke tanah yang mengakibatkan rele differential busbar bekerja. Dari hasil Analisa, rele differential busbar bekerja dikarenakan adanya pembacaan arus yang tidak seimbang sehingga mengakibatkan trip Busbar A yang terhubung dengan IBT 2. Kata Kunci : Busbar, Relay Differential, GISTET 500 kV Durikosambi.
