Abstract

Energy needs continue to increase. Currently, the demand for electrical energy is growing at a higher rate than other energies. Based on Energy Outlook 2019, coal-fired power generation still dominates. However, if no new coal reserves are found, then medium to high-quality coal reserves are projected to be exhausted in 2038. To meet the need for electrical energy, it is necessary to utilize the energy available in nature optimally and stable with changes in electrical load. The potential for hydro energy that can be utilized to generate electricity is 75,901 MW. Generators in a power plant have an important role as a converter of mechanical energy into electrical energy to be utilized. However, to be able to use the stability of the electrical energy produced needs to be considered. One way to stabilize the output voltage of a generator can be done by adjusting the excitation current value. Therefore, the purpose of this study is to determine the effect of the self-amplifying excitation system on a synchronous generator on the output voltage produced when there is no electrical load and an electrical load. The test results show that the excitation current greatly affects the output voltage of the synchronous generator. The hope of this research can be applied to the prototype of the vortex turbine pico hydropower plant which is currently being researched as well.
