Analisis Perbaikan Jatuh Tegangan Pada Sistem Transmisi 150kV Gardu Induk Cerme Menggunakan Aplikasi Digsilent

The electrical quality, especially voltage fluctuations, is very important to remain stable in supplying consumers. PT. PLN (Persero) has a minimum limit of -5% and maximum +10% which regulated the Minister Energy Mineral Resources no. 3 2007 transmission system. However, 150 KV system often experiences drops caused by conductors that are too long inappropriate loads, so maintaining good reliable needed. One them GI Cerme double busbar type, separates two Java-Bali sub-systems connected supplies from West Surabaya Lamongan GI. Even so, Lamongan-Cerme network with length 26.77KMS transformer load causes drop, case occurred April 2023 at peak it experienced drop up 137 KV, necessary overcome problem was repaired Cerme. Through digsilent application, possible simulate better planning can be according standards.
