Koordinasi Proteksi Saluran Udara Tegangan Tinggi Pada Gardu Induk Mliwang – Tuban Akibat Penambahan Penghantar PLTU Tanjung Awar-Awar

Salah satu proteksi utama pada sistem proteksi jaringan transmisi 150 KV adalah rele jarak dengan rele arus lebih berarah sebagai proteksi cadangan lokal. Pada penelitian ini di lakukan re-setting koordinasi pengaman SUTT Mliwang – Tuban akibat penambahan jaringan transmisi baru PLTU Tanjung Awar-Awar. Dari hasil penelitian mendapatkan kesimpulan bahwa setting zona 1, zona 2 pada saluran transmisi Mliwang-Tuban mendekati data setting existing, sedang zona 3 terdapat perbedaan setting, sehingga perlu dilakukan peninjauan kembali setting proteksi di transmisi. ======================================================================================================================== One of the primary protection in the protection system of 150 KV transmission network is the distance relay with directional overcurrent relays as a local backup protection. In doing this research in re-setting the security coordination SUTT Mliwang - Tuban due to the addition of new transmission lines power plant Tanjung Awar-Awar. From the results of the study came to the conclusion that the setting zone 1, zone 2 on the transmission line Mliwang-Tuban approaching the data existing settings, while zone 3 there are different settings, so that should be a review of protection in the transmission setting
