Abstract
Overcurrent rele (OCR) merupakan komponen penting dalam sistem proteksi tenaga listrik. Salah satu parameter yang harus di setting pada OCR adalah arus pick up (Ip) dan time dial setting (TDS). Terdapat beberapa metode optimasi yang pernah dilakukan untuk mendapatkan koordinasi rele yang optimum dengan melakukan setting time dial seperti genetic algorithm (GA), particle swarm optimization (PSO), fire fly algorithm (FA) dan grasshopper optimization algorithm (GOA). Dalam penelitian ini setting TDS dilakukan dengan menggunakan metode grey wolf optimization (GWO). Algoritma GWO berhasil mendapatkan nilai setting TDS yang optimum pada setiap OCR. Hal ini dibuktikan dengan pengujian yang dilakukan menggunakan aplikasi ETAP, rele primer dan rele sekunder dapat berkoordinasi dengan baik untuk mengamankan gangguan 3 fasa yang terjadi pada setiap bus. GWO juga memiliki konvergensi yang lebih cepat daripada GOA sehingga bisa memiliki kemampuan menemukan nilai setting TDS yang lebih handal. Selain itu objectif function GWO lebih baik daripada GOA sehingga dapat bekerja lebih efektif. Berdasarkan hasil pengujian ini, algoritma GWO menunjukkan kelayaknnya untuk diterapkan secara langsung untuk mencari nilai setting TDS yang optimum dalam menentukan setting koordinasi rele.

Overcurrent relay (OCR) is an important component in the electric power protection sistem. One of the parameters that must be set on the OCR is the pickup current (Ip) and time dial setting (TDS). To achieve optimum relay coordination by setting the time dial, several optimisation methods have been used such as genetic algorithm (GA), particle swarm optimisation (PSO), fire fly algorithm (FA) and grasshopper optimisation algorithm (GOA). In this study, the TDS setting was determined through the grey wolf optimisation (GWO) method. The GWO algorithm was able to determine the optimum value of the TDS setting for each OCR process. This is validated by the results of tests conducted using the ETAP application. The primary and secondary relays are able to coordinate effectively to secure three-phase faults that occur on each bus. Furthermore, GWO demonstrated a superior convergence rate in compared to GOA, therefore enhancing its capacity to identify a more optimal TDS setting value. Furthermore, the objective function of GWO is more effective than that of GOA, thereby enhancing its ability to function in a more optimal manner. The results of this test demonstrate that the GWO algorithm is a reliable method for directly identifying the optimal TDS setting value for determining relay coordination settings.
