Abstract

Interkoneksi plant PT Chandra Asri dan PT Tri Polyta menyebabkan peningkatan arus hubung singkat, maka perlu dilakukan analisis ulang terhadap koordinasi proteksi rele arus lebih. Selain kontinuitas dan keandalan sistem tenaga listrik pada perusahaan, keamanan merupakan hal yang penting. Faktor keamaan suatu perusahaan dapat dilihat dari besarnya nilai insiden energi yang terjadi. Nilai insiden energi didapatkan dari hasil simulasi evaluasi arcflash pada kedua plant. Selain besarnya nilai insiden energi yang terjadi ketika gangguan, evaluasi arcflash juga dapat menentukan jarak perlindungan busur api. Menurut hasil analisis yang dilakukan pada tipikal koordinasi, terdapat bus yang memiliki nilai insiden energi terlampau besar. Disarankan untuk menggunakan rele differensial karena waktu operasi rele differensial lebih cepat sehingga dapat mengurangi besarnya nilai insiden energi yang terjadi. ==================================================================================================== The interconnection of both plants, PT Chandra Asri and PT Tri Polyta, cause an increase in short-circuits current. It is necessary to re-analyze the coordination of the over current protection relay. In addition to the continuity and reliability of the electric power systems in the enterprise, security is important. The security’s factor of a company can be seen from the value of the incident energy that occurred. The value of the incident energy can be obtained from the simulation of arcflash evaluation on both plants. In addition to the large value of the incident energy that occurred, arcflash evaluation can also determine the distance of flash protection boundary. According to the results of the analysis performed on a typical coordination, there are buses that have large value of incident energy. It is recommended to use differential relay due to its faster operating time in order to reduce the value of the incident energy that occurred.
