A hybrid power plant development (a combination of wind and solar energy) as an alternative energy to faculty of mathematics and natural sciences Universitas Negeri Jakarta

The depletion of the fossil fuel supply, provoking a lot of research focused on alternative or renewable energies. A hybrid power plant system (a combination of wind and solar energy) as an alternative energy to Faculty of Mathematics and Natural Sciences Universitas Negeri Jakarta is developed. The advantages of a hybrid power generation system are to combine the advantages of each power source so that each one fills the weaknesses of the other under certain conditions, so that the overall system can operate more economically and more efficient. In this research, ESM50W is used as a source of solar electricity and the 24VDC generator is used as a power plant from wind turbines. The solar power plant has an optimal voltage of 17.2 volts and an optimal current of 2.91 A. Based on the results of the measurement of the efficiency of solar power plants approximately to 14.4%. The tachometer is used to measure the speed of the wind passing through the wind turbine. The cut in speed of the wind turbine used is approximately 3 m/s. The voltage generated at a speed of 3 m/s is approximately 49.3 mV with a turbine rotation speed of 17.4 rpm.
