| Abstract | The electricity plays an essential role on socio-economic development in Vietnam. However, in some places, particularly Travinh city, the existing power station cannot meet the increasing customers' demand of power consumption due to high power loss and voltage drop during distribution. Evaluation of voltage drop and power loss to improve the overall efficiency of the power distribution system is prerequisite issue in power station. This research concentrated on planning for distribution expansion and the use of shunt capacitors in primary distribution network of Travinh city for power loss minimization and voltage improvement. The Power System Simulator/Advance Distribution Engineering Productivity Tools (PSS-ADEPT) 5.0 had been used to analyze the system performance and evaluate the impact of CAPO on the sample distribution system. The selection for conductor size, transformer, and CAPO for long-term distribution expansion planning, including two stage (2009 to 2015: stage-1 and 2015 to 2020: stage-2), was optimized. The calculation of net present worth (NPW), internal rate of return (IRR) and payback period for these stages also was included. The analysis results indicated that the existing distribution infrastructures alone will not be able to meet the growing electricity demand of Travinh city in future. To improve efficiency of distribution system, transformers must be installed in stage-1; and transformers, capacitors and cables must be installed in stage-2. Besides power loss reduction, these proposed schemes were seen to significantly decrease in voltage drops, thereby improving the overall efficiency of the power distribution system. Based on the results of calculation of NPW, IRR and payback period, the stage-1 has more efficient than stage-2. |
