Abstract :
The electric power interconnection system is a system that consists of several power centers or generators which are connected from one to another through a transmission line and serve all loads on the substation (GI) connected to the distribution system. Based on the 2019-2028 Electricity Supply Business Plan (RUPTL) in 2023, there will be interconnection planning for the Barito Sub System (South and Central Kalimantan) and the Mahakam Sub System (East and North Kalimantan). Planning analysis was carried out to determine power losses, voltage profiles, and conductor capabilities with a simulation using the Electric Transient Analysis Program (ETAP) application. The results of the interconnection planning analysis showed power losses of 50MW or 0.4% with tension profiles in several areas such as Malinau, Sebuku, Nunukan, Sei Menggaris, Tj. Selor, Talisayan, Maloy, Tj. Redep experiences over voltage where the voltage in some of these areas didn?t meet the PLN Standard (SPLN 1: 1995) + 5% and -10% of the nominal voltage so that a reactor was installed to reduce the voltage, the highest carrying capacity was in L-Asam-Asam to Pelaihari which is 47.9% and T-Ulin 1 which is 203.9%.
