Abstract (Abstrak)

There are three main requirements to meet the criteria both in the electric power system, namely reliability, quality, and stability. Stability is the ability of the system to return to work normally after experiencing interference. System stability analysis is a guide for operators to detect or prevent voltage drops and power outages. This research discusses the stability of the 150 KV electrical system in South Sulawesi before and after interconnection with the Sidrap and Jeneponto Wind Power Plant. The method used is the Line Stability Index (Lmn Index) to view the voltage profile. Index Lmn coding is run and simulated using Matlab. Validation is done by IEEE 14 bus simulation data, and comparing the results of the analysis before and after penetration with PLTB. The study was conducted on the Sulselbar 150 KV system before penetration with PLTB, namely 44 buses, 14 generators, and 52 lines / networks. The highest Lmn index result is the network from bus 38 to bus 39 that is equal to 0.0292. Second is bus 15 to bus 16 which is 0.0291, and third is bus 40 to 42 that is 0.0273. After penetration with PLTB Sidrap and Jeneponto, the number of generators will be 16 generators. The highest Lmn index results are from bus 38 to 39 that is 0.0292, then bus 15 to bus 16 that is 0.0290 ranks second, and bus 40 to 42 equals 0.0272 or keeps the third order. After the sidrap load bus is converted to a bus generator, the Lmn index before in reactive power supplied to the load by a generator is a certain thing, this condition must be maintained so that the plant continues to work in stable conditions.
