Abstract
PT. Pertamia RU IV Cilacap bersama PLN melakukan integrasi terhadap sistem kelistrikannya. Integrasi yang telah dilakukan berupa pemindahan beban-beban non esensial dari eksisting ke feeder PLN untuk disuplai langsung oleh sumber PLN. Sistem ini merupakan sistem tahap 1 yang dilakukan Pertamina bersama PLN guna meningkatkan keandalan sistemnya. Sistem proteksi yang baik harus bisa dengan cepat meminimalisir gangguan yang terjadi sehingga hal-hal yang tidak diinginkan seperti terhentinya sistem produksi listrik, dan kerusakan alat dapat dihindari. Dalam koordinasi proteksi, hal utama yang perlu diperhatikan untuk peningkatan kualitas relay pengamannya yakni penentuan parameter dari Time Dial Setting (TDS). Pada relay arus lebih inverse (51), penentuan parameter TDS dalam praktiknya seringkali operator mengalami kesulitan menemukan setting yang tepat . Oleh karena itu, untuk memudahkan serta mempersingkat waktu perhitungan setting relay arus lebih inverse pada tugas akhir ini dilakukan perhitungan TDS dengan metode Adaptive Modified Firefly Algorithm. Hasil tugas akhir ini yakni memperoleh setting TDS yang tepat dengan waktu operasi dan CTI yang minimum serta pemilihan kurva TCC guna mengetahui bahwa koordinasi proteksi sudah tepat.
==============================================================================================================================
Based on Government Regulation, PT. Pertamina RU IV Cilacap together with PLN integrated its electricity system. Integration that has been carried out is transferring non-essential loads from existing into PLN feeders to be supplied directly by PLN Sources. This system is phase 1 system carried out by Pertamina along with PLN to improve their system reliability. A good coordination protection system must be able to quickly isolate an interruption that occurs in system so that unwanted things such as cessation of electricity production system, severe equipment damage, even a blackout can be avoided. The important thing that needs to be considered in coordination protection of power system is to improve the performance of relay by determining relay setting parameters itself which is Time Dial Setting (TDS). In the practice, frequently operators have difficulty in finding the right setting of TDS Relay(51). It takes a long time to find the right setting of TDS because they use trial and error in finding it. To simplify and shorten the calculation time of inverse Overcurrent Relay settings, in this final project writer make a program to calculate TDS with Adaptive Modified Firefly Algorithm Method. The result of this final project is to obtain the right setting of TDS with minimum time operation, CTI, and TCC curve selection as well to ensure the coordination protection is correct.
