Abstract
PT. Petrokimia Gresik memiliki sistem dengan komponen kelistrikan yang sangat kompleks dan memerlukan perhatian lebih pada segi koordinasi proteksi sistem kelistrikannya. Terjadinya gangguan terhadap frekuensi saat terjadi gangguan pada pembangkit PLN menyebabkan generator pembangkit pada Gresik Gas Cogeneration Plant PT. Pupuk Indonesia Energi mengalami trip. Sehingga perlu dilakukan perubahan koordinasi proteksi generator pembangkit dan juga peningkatan kualitas setting dari rele pengaman tersebut. Oleh sebab itu diusulkan topik tugas akhir ini sebagai studi untuk membantu setting koordinasi proteksi rele pada generator turbin gas 26 MW Gresik Gas Cogeneration Plant.
Kondisi operasi abnormal pada generator dapat menyebabkan kerusakan pada generator dan ketidak andalan pada sistem kelistrikan. Evaluasi rele-rele yang aktif meliputi rele eksitasi berlebih, rele frekuensi, rele daya balik, rele generator unbalance, dan rele loss of field pada topik ini dikhususkan untuk memperbaiki setting eksisting untuk disesuaikan dengan standar yang ada, sehingga generator akan terlindungi dengan baik saat terjadi gangguan eksternal generator.

PT Petrokimia Gresik has a system with very complex electrical components and requires more attention in terms of coordinating the protection of the electrical system. The occurrence of disturbances to the frequency at the time of the disruption of PLN generator caused the generator at the Gresik Gas Cogeneration Plant PT. Pupuk Indonesia Energi is on a trip. So it is necessary to change the coordination of generator protection and also to improve settings quality of the safety relay. Therefore, the topic of this final project is proposed as a study to assist the setting of relay protection coordination in the Gresik Gas Cogeneration Plant gas turbine generator 26 MW.
Abnormal operating conditions on the generator can cause damage to the generator and unreliability of the electrical system. Evaluation of active relays including over-excitation relays, frequency relays, reverse power relays, generator unbalance relays, and loss of field relays on this topic is devoted to improving the existing settings to be adjusted to existing standards, so that the generator will be well protected when an accident generator external fault occurs.
