Abstract

Solar energy (solar) provides many benefits to human life. One of the utilization of solar energy that can be done is in the form of Solar Power Generation (PLTS). In this thesis will design of a solarcell power system with a capacity of 10 MW on-grid with location in Yogyakarta. Performance solar cell power system 10 MW on-grid simulated using software RETScreen Clean Energy ProjectAnalysis Software, which was designed by Natural Resources Canada. The project began with a prefeasibility study of the solar cell power system 10 MW on-grid using RETScreen software that hasan extensive database of meteorological data including daily global horizontal solar radiation and also databases of various components of renewable energy systems from different manufacturers.Technical and financial performance of the solar cell power system 10 MW on-grid simulated using RETScreen software. Preliminary analysis of the simulation results show that this project is sociallybeneficial to the community. The draft is expected to be used as a model to develop a network of Solar Power System (PLTS).

Abstract

Media information which presents the technical data and specifications of the transformer is a nameplate, one of the data listed on the nameplate is the type of vector group transformer, vector group transformer which can inform you about the types of relationships winding on the transformer and the magnitude of the phase difference between the primary to the secondary. Vector group listed on the nameplate is particularly useful when the transformer will be operated in parallel, because the terms of parallel operation of transformers is to have the same type of vector group. Refers to the standard SPLN 50: 1987 and IEC 60076-1, vector Group of the routine work done to determine the type of relationship turns on the primary and secondary sections to match the nameplate. Methods to determine the type of vector group is done by connecting one of the terminals similar between the primary with the secondary, then the measured value of the voltage between the other terminal, the results of these measurements refer to the vector group testing formula and referring to the vector diagram measurement testing group.

Abstract

Savings in using electric fuel in the use of fossil fuel electricity must be reduced. This research was conducted as an effort to save the use of electricity by using solar power plants as the main source, with the making of this research it is hoped that it can be used for electricity consumption at a more economical cost and the use of electric stoves can be used in daily life. The selection of materials and this research can be seen from the existing literature and field studies. Solar power plants in this study use some equipment such as solar panels that by utilizing solar energy will be a source of initial voltage, a regulator control battery as a regulator of electric power charging to the battery (battery), battery (battery) as a storage of electrical power, and an inverter for convert the dc to ac voltage from the battery (battery). The equipment is the main equipment used to turn on the electric stove which is the main burden in this application. This research is expected to be a reference for the use of solar energy for electric stoves in an effort to save electricity. This equipment also refers to the amount of power used on an electric stove of 300 W, with an observation time of 7 hours a day, so that it will produce a current that flows at 6.8 A, and a voltage of 17.3 Volts which occurs at 11.00 WIB

Abstract

The generator is a source of electrical energy that will be distributed to the substation which will then be channeled back to consumers. The separator is the equipment at the substation which supports the performance of the equipment. Maintenance on the separator should be maintained on a regular basis which consists of cleaning and testing. One of the tests is contact resistance. This test is carried out to determine the resistance value of the Separator contact according to the standard. Power loss is affected by a high resistance value, because the power loss is the square of the current multiplied by the resistance of the contact. This study was conducted to determine the value of contact resistance against power loss by comparing the value of contact resistance in 2020 and 2021. The power loss obtained is relatively small, namely the highest power loss is in the 2021 phase R, which is 6.417 Watt or 0.006417 kW. Meanwhile, the lowest power loss is in phase T in 2020, which is 2.603 Watt or 0.002603 kW. The effect of contact resistance in this study is that if it is found that the contact resistance value exceeds the standard so that a high contact resistance value is obtained, it will be able to cause the equipment to become hot, and when it reaches its melting point, it will be able to melt the separating knife or disconnecting switch, so that the temperature does not change. can be held back by the contact resistance according to its ability, there will be an explosion at the Separator contact which will cause a trip.
