Abstract

Short circuit fault analysis is needed to determine the amount of short circuit current flowing in a system. This study discusses the single-phase short-circuit current to the ground at the point where the disturbance occurs from the base of the network to the end of the Malewang feeder network. The purpose of this study was to determine the amount of short circuit fault current in the Electric Power Distribution System at PT PLN (Persero) UP3 South Makassar ULP Kalebajeng. This study used the ETAP program and manual calculations. The results of the study found that the contribution of the largest single-phase short-circuit fault current to the ground in the Malewang feeder occurred on Buses located at the base of the network close to the Substation, namely Bus 1 (Exim-Rec Kalaserena) of 0.311 kA, while thesmallest Buscontribution occurred on Buses located at the end of the network far from the Substation, namely Buses 14 (Bilonga) of 0.292 kA. From the results of the study, it can be concluded that the farther the interference bus is from the Substation, the greater the channel impedance. The greater the impedance, the smaller the short-circuit current.

用ETAP分析南望加锡3号厂配电系统短路故障

为了确定系统中短路电流的大小，需要进行短路故障分析。本文讨论了从麻王馈线网底部到麻王馈线网末端发生扰动点处到地的单相短路电流。本研究的目的是确定PT PLN (Persero) UP3 South Makassar ULP Kalebajeng配电系统中的短路故障电流量。本研究采用ETAP程序和人工计算。研究结果发现，Malewang馈线单相短路故障电流对地贡献最大的母线位于靠近变电站的网络底部，即母线1 (Exim-Rec Kalaserena)为0.311 kA，而母线贡献最小的母线位于远离变电站的网络末端，即母线14 (Bilonga)为0.292 kA。从研究结果可以看出，干扰母线离变电站越远，通道阻抗越大。阻抗越大，短路电流越小。
