Abstract

This research was conducted to obtain the optimal DG location with the aim of minimizing power losses in feeders. Penyulang Abang has a length of 207,946 kms with power losses of 1,105 MW. One way to reduce power losses is to install distributed generation. Distributed generation is installed in four Abang feeder locations. Optimization is done by using the Quantum Genetic Algorithm (QGA) method. Quantum Genetic Algorithm is an evolutionary algorithm. Genetic Quantum Method Algorithms are based on the concept of quantum bits (qubit) and the superposition of quantum mechanical forms. The purpose of this method is to select the best results from the results obtained. The final result of the QGA method is the most efficient distributed generation and capacity placed in several Abang feeder locations, namely buses 1, 5, 7 and 302 with capacities of 0.374 MW, 1,894 MW, 1,988 MW and 0.500 MW, respectively. So that the power losses are reduced to 0.234 MW.

Abstract

This study optimized the installation of capacitors on the distribution grid system in Penyabangan feeder, Singaraja, Bali using the Quantum Genetic Algorithm method to reduce the impact of increasing reactive currents. This feeder, consisting of 162 buses in which 62 buses are directly connected to the load and 5 buses are connected to medium voltage cosumers. The results of this study are obtained by the capacity of capacitors installed in 31 buses that have a power factor value less than the permitted limit and the power loss values decrease from 0,0674 MW and 0,0546 MVAr to 0,0543 MW and 0,0442 MVAr.

Abstract

The increasing demand for electrical energy in Bali requires additional electrical energy supply, while conventional energy such as petroleum, coal and natural gas continue to be used. Therefore, the utilization of non-conventional energy like solar energy should be increased. One of provision of non-conventional electric energy which is ready to be widely used is using PLTS Photovoltaic technology. The data analysis in this study uses manual calculation method to calculate electric power requirement, setting the result for electrical power, calculating the amount and capacity for solar module and inverter, calculating slope angle and location of solar module. PLTS uses a hybrid system with PLN, which works automatically to be controlled by the inverter control system. PLTS capacity of 148,274 kW supply 30% of the electrical energy consumption in the building of 2,310 MWh.

Abstract

PT. Sejahtera Indobali Trada is a car maintenance and sales service company. Excellent customer satisfaction is prioritized by this company. The best service must be done by using facilities effectively. For this reason, energy management is needed. Energy auditing is the first step in energy management. Energy audit to find out the use of electricity and opportunities. Energy audit includes the contents of energy data with available data and calculating Energy Consumption Intensity (IKE) based on the data collected. Previously, PT. Sejahtera Indobali Trada has never conducted an energy audit. This research method is done by calculating and comparing electrical energy in energy and energy systems. The results were obtained at 6.82% with the IKE difference between pre-audit and post-audit amounting to 0.59 kWh / m2 / month.

Abstract

At present the power plant has a high dependence on energy sources such as diesel, natural gas and coal, while its energy source in nature is increasingly scarce, this situation encourages the development of renewable energy, one of which is in micro hydro power plants. This study aims to determine the effect of the width of the work triangle on the highest rpm produced. the fall of water on the pinwheel is set from the position angle of the nozzle 00, 150, 300, 450, 600, 750 and from the angle of the nozzle 00, 50, 100, 150, 200, 250, 300, 350 and 400 on the semicircular blade turbine, triangle blade turbine , and fin blade turbines. Semicircular turbine blade, working triangle area produces greater rpm at position of angle nozzle 00 and angle of nozzle 250 with area of work triangle 360,36 cm2, where the position produces 216 rpm at windmill rotation and 1626 rpm at generator rotation. When the nozzle position angle 150 and the nozzle angle 200 with the working triangle area 264.27 cm2, produce 221 rpm at the pinwheel rotation and 1711 rpm at the generator rotation. while at the nozzle position angle of 300 and the angle of the nozzle 100 the area of the triangle works 134.37 cm2 and produces 173 rpm at the spinning wheel and 1307 rpm at the generator rotation. on the triangle blade turbine and fin blade, the working triangle area does not affect the rpm produced.
