Abstract

Kontinuitas daya, efisiensi energi, dan keamanan sistem tenaga listrik adalah alasan utama yang menyebabkan peningkatan penambahan distributed generation pada saluran distribusi listrik. Dengan penambahan distributed generation pada sistem distribusi mengakibatkan kontinuitas daya dan efisiensi daya akan terjaga, namun akan mengakibatkan konfigurasi sistem berubah-ubah seiring dengan penambahan distributed generation. Perubahan konfigurasi sistem tersebut akan berpengaruh pada setting rele proteksi sistem eksisting. Apabila setting rele menggunakan setting eksisting pada saat terjadi perubahan konfigurasi sistem maka kemungkinan akan terjadi miss coordination atau loss coordination pada sistem, untuk menghindari hal tersebut, diperlukan setting rele yang adaptif. Dalam proses adaptasi rele, parameter-parameter rele harus ditentukan dari masing-masing konfigurasi sistem. Penentuan parameter-parameter rele dapat dilakukan secara manual, namun cara ini terkadang membutuhkan banyak waktu karena setting manual dilakukan dengan proses trial and error. Proses trial and error dapat dihilangkan dengan mengoptimalisasikan rele, dengan optimalisasi rele, penentuan parameter rele dapat dilakukan dengan sekali menjalankan program. Pada tugas akhir ini, proses pengoptimalisasian rele menggunakan firefly algorithm. ====================================================================================================== Power continuity, energy efficiency, and power system security are the main reasons that resulted significant penetration of distributed generation on distribution power system. The Addition of distributed generation on distribution power system will causing power continuity and energy efficiency will be maintained, but the other result is in a system configuration change along with the addition of distributed generation. The system configuration changes will affect the existing system of protection relay settings. If the system configuration changes and the relay still using the existing settings, it may lead to a miss coordination or loss coordination in the system. To avoid this, an adaptive relay setting is needed. In the relay adaptation process, the parameters should be determined from each system configuration. The determination of the parameters can be done manually, but in manual settings sometimes requires a lot of time because it’s done by trial and error process. The process of trial and error can be eliminated by optimizing the relay, with optimization of relay the parameters determination can be done with a running program. In this final project, the optimization relay process using firefly algorithm.
