Abstract
In an interconnection network system that serves vital power supplies for the public interest, reliable reliability is needed so that the power system can be continuously maintained. The reliability of a system includes how the engineer can design the existing protections and analyze the possible disturbances that can occur in the future so that the reliability of a power system can be maintained. It is in this basic concept that the light rail transit interconnection also needs to be built so that the reliability of supply power in train operations can be maintained and can always serve public transportation. In creating this reliability, a study is needed covering the electricity system to engineering design for protection, so in this paper the author presents the research design related to the 20kV LRT JABODEBEK interconnection protection test across Cawang - Cibubur services. In this design and testing, the ETAP 16.0.0 software is used so that we can design and analyze the interconnection system as well as the overcurrent protection system especially due to existing disturbances. Overcurrent protection is protection that specifically discusses how to protect the network from overcurrent disturbances. Overcurrent can be caused by various factors where the cause of abnormal interference is caused by a short circuit between phases and a short circuit from phase to ground. The protection used in this study is the overcurrent type relay from the ABB manufacturer which is specifically integrated into the RED615 system. Key Word : 20kV interconnection, JABODEBEK LRT, Overcurrent Protection, ETAP 16.0.0, Overcurrent Relay, and RED 615. Dalam sistem jaringan interkoneksi yang melayani supply tenaga vital untuk kepentingan umum dibutuhkan suatu keandalan yang mumpuni sehingga sistem tenaga dapat terus terjaga terus menerus. Keandalan suatau sistem mencakup tentang bagaiaman sebagai enggineer dapat mendesain terkait proteksi-proteksi yang ada serta menganalisa kemungkinan-kemungkinan gangguan yang dapat terjadi di masa depan sehingga keandalan suatu sistem tenaga dapat terus terjaga. dalam konsep dasar inilah interkoneksi light rail transit juga perlu di bangun sehingga keandalan supply power dalam operasional kereta dapat terus terjaga dan dapat senantiasa melayani transportasi umum. Dalam menciptakan keandalan tersebut dibutuhkan suatu penelitian mencakup sistem ketenagalistrikan sampai dengan desain enggineering untuk proteksi, sehingga dalam penulisan ini penulis menyajikan terkait desain penelitian sampai dengan pengujian proteksi interkoneksi 20kV LRT JABODEBEK lintas pelayanan cawang - cibubur. Dalam desain dan pengujian ini di gunakan software ETAP 16.0.0 sehingga kita dapat mendesain dan menganalisa terkait sistem intekoneksi sekaligus sistem proteksi secara khusus overcurrent akibat gangguan yang ada. Proteksi overcurrent yaitu proteksi yang secara khusus membahas tentang bagaimana mejaga jaringan dari gangguan arus lebih. Overcurrent dapat di sebabkan oleh berbagai faktor dimana penyebab gangguan yang tidak normal di sebabkan oleh short circuit antar phase maupun short circuit phase to ground. Proteksi yang di gunakan dalam penelitian ini yaitu rele dengan jenis overcurent dari pabrikan ABB yang secara khusus dipadukan di dalam sistem RED615. Kata Kunci : Interkoneksi 20Kv, LRT JABODEBEK, Overcurrent Protection, ETAP 16.0.0, Overcurrent Relay, dan RED 615.
