HYDROELECTRIC POWER PLANT (PLTA) OF PEUSANGAN 1 AND 2 4X22MW AT SUBSISTEM ACEH
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2017, Vol 6, Issue 4
Abstract
Hydroelectric power plant contributes much for modern people who use electric equipment. This study aims to analyze the power flow of the 150kV Aceh Power System under maximum loading conditions before and after the entry of Peusangan hydropower in 2018. The addition of new power plants is one way to fulfill people's need for electric energy so that a power flow study is needed to see the impact of the addition. The problem of this research is limited to determining the value of the substation voltage, active power flow and reactive power on various channels and power losses before and after Peusangan hydropower comes. The method of power flow approach that will be used in this research is Gauss-Seidel method with accuracy factor 0.0001 through simulation with the help of ETAP 12.6.0 software. The simulation is done in two scenarios: 1) Power System of 150kV Aceh at present; and 2) Entrance of Peusangan Power Plant on Power System 150kV Aceh. The simulation result shows that the Banda Aceh substation is a substation near the undervoltage limit on the upcoming Aceh 2018 subsystem with the value of the voltage is 137.14 kV or 91.43%. The highest active power and reactive power after the addition of the power plant are on the Lhokseumawe - Arun channel of 105,897 MW and 51,734 Mvar. The highest power losses after the inclusion of new power plants occurred on the Sigli - Banda Aceh line of 1,309 kW and 4,705 kvar.
