Abstract

Sebuah sistem proteksi yang efektif harus mampu melindungi dan meminimalisir dampak suatu gangguan secara cepat dan tepat, serta menghindari dampak negatif, seperti kerusakan perangkat yang lebih parah, terhentinya pasokan daya dan potensi bahaya bagi manusia. Untuk meningkatkan kehandalan sistem proteksi, koordinasi proteksi yang mengintegrasikan berbagai relay menjadi penting. Ketika gangguan terjadi dalam sistem tenaga listrik, circuit breaker harus dapat menonaktifkan gangguan dengan membuka circuit breaker. Urutan pembukaan circuit breaker dimulai dari yang paling dekat dengan sumber gangguan dan dilanjutkan dengan circuit breaker cadangan. Aspek krusial dalam koordinasi proteksi, terutama pada relay arus lebih adalah pengaturan parameter Time Dial Setting (TDS). TDS mengontrol waktu operasi relay dalam menanggapi gangguan. Umumnya, nilai TDS dihitung secara manual untuk mencapai nilai TDS minimum. Namun, untuk mendapatkan nilai TDS yang optimal dalam koordinasi dengan relay lain, seringkali diperlukan metode uji coba dengan menggeser kurva hingga mencapai nilai Circuit Time Interval (CTI) yang dianggap sesuai. Untuk mempermudah perhitungan dan memperoleh nilai TDS yang akurat, digunakan suatu algoritma khusus. Penelitian ini membahas perhitungan time dial setting inverse time overcurrent relay menggunakan metode adaptive modified firefly algorithm pada sistem kelistrikan Plan Nikel di Sulawesi. Metode ini bertujuan untuk mendapatkan nilai TDS minimum yang optimal. Hasil dari penelitian ini adalah mendapatkan nilai TDS yang sesuai dengan perhitungan manual serta memastikan bahwa koordinasi proteksi antar relay terimplementasi dengan baik.

An effective protection system must be able to protect and minimize the impact of a fault quickly and appropriately, and avoid negative impacts, such as severe damage to equipment, interruption of power supply, and potential risks to human safety. To improve the reliability of the protection system, protection coordination that integrates various relays is very important. When a fault occurs in the power system, the circuit breaker must be able to isolate the fault by opening the circuit. The order of opening the breakers starts from the circuit breaker closest to the source of the fault, followed by the backup circuit breaker. An important aspect of protection coordination, especially for overcurrent relays, is the adjustment of Time Dial Setting (TDS) parameters. The TDS controls the response time of the relay to a fault. Usually, the TDS value is calculated manually to get the minimum TDS value. However, to obtain the optimal TDS value in coordination with other relays, a trial-and-error method is often required by shifting the curve until it reaches a Circuit Time Interval (CTI) value that is considered appropriate. To simplify calculations and obtain accurate TDS values, specialized algorithms are used. This research discusses the calculation of time dial settings for inverse time overcurrent relays using an adaptively modified firefly algorithm on the Nickel Plan electrical system in Sulawesi. This method aims to obtain the optimal minimum TDS value. The results of this study provide a TDS value that is in accordance with manual calculations and ensures the protection coordination between relays runs well.
