Abstract

Penerbangan adalah satu kesatuan sistem yang terdiri atas pemanfaatan wilayah udara. Salah satu fasilitas yang sangat penting adalah penyediaan catu daya listrik. Untuk memberikan catu daya listrik dari PLN sangat berpengaruh terhadap penyediaan energi listrik pada Bandar Udara Haluoleo Kendari. Energi listrik dari PLN, tidak selalu continue dalam penyalurannya suatu saat pasti terjadi pemadaman dari PLN. Memiliki catu daya cadangan seperti generator set dengan kondisi generator disinkronisasi termasuk untuk menambah kehandalan. Melakukan penelitian Analisis Sistem Sinkronisasi Generator 2×2 MW. Bertujuan mengetahui apakah sistem sinkronisasi generator sebagai suplai cadangan bisa memback-up beban yang ada. Dari hasil sinkronisasi aliran daya generator unit 1 dan generator unit 2 berbeban pada saat PLN cut off. Sehingga daya terpakai pada generator unit 1 setiap fasa sebesar R: 123,72 kW, S: 123,40 kW, dan T: 126,14 kW, dan daya terpakai pada generator unit 2 setiap fasa sebesar R: 126,12 kW, S: 124,70 kW, dan T: 124,15 kW. Hal ini menunjukkan total beban terpakai Bandar Udara Haluoleo Kendari saat PLN cut off mencapai 80 % dengan daya sebesar 748,23 kW. Berdasarkan hasil software ETAP 12.6.0 simulasi load flow analysis sinkronisasi menunjukkan aliran arus, tegangan, dan daya pada generator. Arus sebesar 878,5 A, tegangan 0,38 kV, dan daya semu 578 kVA, tegangan di naikan pada transformator step up 1000 kVA keluaran sekunder pada transformator step up 19,114 kV, arus 33,7 A, dan daya semu 1117 kVA. Selanjutnya tegangan di turunkan pada transformator step down 1250 kVA keluaran sekunder pada trafo step down 0,35 kV, arus 1776,1 A, daya nyata 915 kW, dan daya semu 1076 kVA. Dengan beban pada Bandar Udara Haluoleo Kendari sebesar 1110 kVA

Abstract

In today's era, people's need for electrical energy is increasing along with technological advances and increasing people's standard of living, so that electric energy has become a basic need for people in meeting their needs. As a provider of electricity PLN is required to meet the needs of the community for electric power efficiently and quality. The process of sending electrical power to consumers has a problem, especially when the drop voltage, this happens if the voltage at the base of the delivery with the voltage at the receiving end occurs a difference. The analysis was conducted to find out the magnitude of the drop voltage that occurred in the transmission line at Kendari New Substation - Puuwatu Substation 150 kV, as well as calculate the economic value due to the loss of electrical power. The calculation method is done using drop voltage equations and analysis using ETAP software. The reference standards for service voltage variations used are SPLN.1-1995 and IEEE 1159-1995. Based on the results of the study it can be concluded that: (1) The calculation manually the value of the drop voltage is 0.371 %; (2) The result of the simulation of drop voltage using ETAP software is 0.143 %; In accordance with the standards SPLN.1-1995 and IEEE 1159-1995 the drop voltage that occurred is still within the tolerable limit of less than 5%; (3) Calculation of economic losses due to loss of electricity during january to June amounted to Rp161,408,119.92

Abstract

The current Southeast Sulawesi electricity system has two main power plants, namely the Nii Tanasa PLTU with a capacity of (1´30 MW) and the Moramo PLTU (DSSP) with a capacity of (2´50) MW and has also been interconnected with the South Sulawesi electricity system with the addition of a substation in Bombana, meaning that the power needs of the Kendari electricity system have increased, which can result in increased losses and drop voltage . The purpose of this study is to see the condition of the large value of Current, Voltage, active power flow and reactive power on each bus between channels, and to see the value of the short circuit fault current at the fault location point. after the addition of the Bombana GI, Single line modeling using the help of ETAP 19.0.1 software. based on the results of the research that has been done the value of the power generated by the generator after the entry of the Bombana GI is 271.527 MW where previously it was 211.975 MW, the voltage condition before the entry of the Bombana GI is 96.05% - 99.23% of the previous 97.95% - 99.53%, based on the percentage of Drop Voltage is in the range of 0.022%−0.872% which is still within the SPLN operational standard limit. Then the Total Losses on the channel is 1168.92 KW. The largest Short Circuit current value after the entry of the Bombana GI in the Southeast Sulawesi system for 3-phase short circuit current is 10.267 KA, phase to ground is 10.637 KA, phase to phase is 8.920 KA, and two phases to ground is 10.537 KA.
