Abstract
Peralatan yang berada di gardu induk rentan tersambar petir karena berada diruang terbuka. Sehingga diperlukan sistem perlindungan petir eksternal untuk memberikan perlindungan kepada bangunan dan peralatan sistem tenaga listrik dari sambaran petir langsung. Pada tugas akhir ini dibahas mengenai simulasi dan pemodelan perlindungan gardu induk dari sambaran petir langsung menggunakan EMTP-RV dan metode bola bergulir di Gardu Induk 150 kV Sukolilo-Surabaya. Melakukan simulasi dengan bantuan perangkat lunak EMTP – RV untuk mendapatkan performa sistem. Dari hasil simulasi diperoleh kenaikan tegangan puncak dipengaruhi oleh arus maksimum yang dihasilkan oleh simulasi petir. Sedangkan kenaikan durasi dari waktu naik (rise time) dari petir akan menurunkan tegangan puncak. Untuk melindungi gardu induk dari sambaran petir langsung dengan konfigurasi pemakaian kawat tanah setinggi 18 m dengan jarak pisah 14 m sudah aman dari sambaran petir langsung. Kemudian diberikan alternatif perlindungan lain yaitu dengan memasang tiang penangkal petir. Menggunakan tiang penangkal petir setinggi 28 meter yang di susun secara segitiga sebanyak 22 buah.

The equipment in the substations are vulnerable to being struck by lightning because installed outside the building. Because of that the external protection system is required to protection to buildings and electrical power system equiqment from direct lightning strike. In this thesis discussed about the simulation and modeling of substations protection from direct lightning strikes using the EMTP-RV and methods of balls rolling in Substation 150 kV Sukolilo-Surabaya. Perform simulations using software EMTP - RV to obtain system performance. From the simulation results obtained peak voltage rise is influenced by the maximum current generated by simulating lightning. While the increase in the duration of the rise time (rise time) of lightning will reduce the peak voltage. To protect the substation from a direct lightning strike to the configuration of the use of the ground wire as high as 18 m with 14 m separation distance was safe from direct lightning strike. Then given another protection alternative is to install the lightning-rod. Using lightning-rod as high as 28 meters in a triangular stacking as many as 22 pieces..
