Impact of connection Taludaa 2 mini-hydro power plant on small scale power load

Abstract

The analysis of the voltage’s profile before and after can also evaluate the JTM 20 kV LH.3 Pohe feeder distribution system when it is connected by the substation PLTMH Taludaa 2 with the power of 2300 kW. The method used in this research is the Newton-Raphson method through the simulation by the help of ETAP 12.6.0 software on requiring single line 20 kV Gorontalo system data, generator data, power transformer data, busbar data and line conduct data. The results of the analysis shows that the average improvement in the voltage profile on all buses is 0.991%, while the power losses after connecting PLTMH Taludaa 2 in a system with a load of 80% of the distribution transformer capacity can reduce power losses by 20.6 kW active power and reactive power about 35.9 kVar reactive power.
