Karakteristik Tegangan dan Frekuensi Generator Induksi Satu Fase Tereksitasi Diri Berdaya Kecil

Abstract

Generators used in remote areas often have to be purchased from another city so that the cost needed to be expensive. An alternative solution is to modify the induction motor available in the market into an induction generator. Therefore, it is necessary to conduct a research to observe the performance of induction generator resulting from the modification of the induction motor. The research was started by connecting the single phase induction generator and the prime mover. The rotational speed of induction generator was controlled by regulating the voltage of the motor used as a prime mover. After the rotational speed reach a certain value, the voltage and the frequency of induction generator were measured by using a multimeter. After that, the energy saving lamps of 24 to 120 watts were connected to terminals of induction generator. Under no-load condition, the results showed that the variation of rotational speed from 1000 to 1200 rpm causes voltage variation from 146,2 to 217,5 volts and frequency variation from 49,2 to 59,6 Hz. When the energy saving lamps were connected to induction generator, the test results showed that the variation of the load from 24 to 120 watts causes the voltage varies from 214,8 to 196 volts, the rotational speed varies from 1154 to 1096 rpm, and the frequency varies from 60,3 to 57,8 Hz
