Abstract

Network development especially the substation can not be separated from the problem of area availability and load which is served on those areas. The placement of the substation should be located close to load centers, so it have network with a wide local area service. To determine area's load center of the next few years can be used with forecast of the long-term electrical loads using micro-spatial method, this method divides the load area into a view grid according to reign administration is the sub-district. This method uses datas related to electricity, socioeconomic, and demographic. In determining the grid peak load (districts) is calculated based on four groups of loads (sectoral). these are the household sector, industrial, commercial, and social. The approach taken in the micro-spatial method uses multiple linear regression model. To follow the trend of land use, then use the dependent variable with peak load's density. Results of peak load density is associated with the land use every sector, for peak load on those area. peak load forecast results for the city of Pekanbaru from 2015 to 2024 indicates a growth rate that varies every area from 4.3% to 20.9%, and growth of peak load average based on sectoral, are household sector 9.22%, industry 13.28%, commercial 7.95%, and social 9.39%.

Abstract

The use of non-linear loads are increasingly widespread. The non-linear load can cause distortion of the voltage wave and current wave. This waveform distortion commonly called harmonics. The problems that can be caused by harmonics include increased energy losses, overheating and low work factor. In practice the presence of harmonics is carrying losses on a variety of tools, one of which is the distribution transformer. In this research designed to determine the harmonic simulation in every winding connection. Software used in this research was ETAP 11.0. Results from this research indicate a winding connection most good to be used in transformer based on the value of THD.Keywords: Harmonic current, Transformer, THD, ETAP, Winding Connection

Abstract

The transformer is the main element that is very important in the distribution of electricity. The fault that occurs in the transformer can blocked the process of distribution electrical energy to consumers. And one of them is the emergence of inrush currents when energizing the transformer is one phenomenon that occurs in electric power and affects differential relay performance. In operating a differential relay sometimes it is a fault which causes the protected transformer to trip despite the fact that the transformer is normal. This study proposes Reducing Inrush Current on the Garuda Sakti Substation Power Transformer, to reduce the inrush current in the power transformer when the power transformer is first turned on. The method used in this study is to use a bridge diode type DC reactor which is simulated using Matlab / Simulink software. By connecting in series with each phase of the power transformer. The simulation results the reduction value of inrush current on power transformer 1 with a difference that is at phase R = 29.7 A phase S = -10 A and phase T = -17.5 A. In power 3 transformer at phase R = 32.7 A , phase S = -11.5 A and phase T = -21.9 A. The result of the reduction in inrush current using the DC reactor is compared with the inrush current value. The result of this reduction in inrush current can reduce the inrush current on power 1 transformer at R phase 14.7%, phase S 5.7% and phase T 9.8%. In power transformer 3 it can reduce to phase R 14.5%, phase S 5.9% and phase T 10.8%Keywords : Inrush Current, Power Transformer, DC Reactor

Abstract

Short circuit fault that occur in the distribution network can breakdown of electricity services to consumers. Therefore, the distance of the fault location needs to be known quickly and precisely. The impedance method can be used to estimate the fault location. Short circuit was simulated by using Panam distribution network model with ETAP 12.6 by applying phase to ground, phase to phase and three phase short circuit fault. The fault location was modeled on bus 19, bus 28, bus 43, bus 81 and bus 133. The input data used is the current and impedance of buses and substations from the simulation. From fault location distance calculation resulted the largest error is 0.0851% with 21,207 meters average distance difference for phase to phase fault, 0.0843% with 21,016 meters average distance difference for phase to ground fault, 0.0215% with 5,356 meters average distance difference for three phase fault.Keywords: distribution system, fault location distance, impedance method
