Experimental Performance Evaluation of a Power Generation System Using SEIG

Abstract

One of the working induction generators is the self-excited induction generator (SEIG). In the self-excited mode, the generator can produce its voltage and frequency and for this it requires a capacitor. Determination of exciting capacitance of the induction generator (IG) is very important in adjusting the capacitance size. The effect of varying the capacitance of this capacitor on the generated output power, voltage, and its frequency has been studied. Besides, these three factors also differ inside by the value of the capacitor, the speed of the generator, the size and the change of the load, and the parameters of the generator. For this purpose, an experimental system, which consists of an AC driver, an induction motor, an induction generator, a step-down transformer, an AC/DC converter, and a controller, was installed. Various loading and excitation capacitor configurations of the IG were also examined at load and no-load. Thus, the experimental analysis of the powers gathered from the output of the generator has been achieved.

“…It is highlighted in [10], [11] the importance of capacitor bank sizing in self-excited three-phase induction generators so that the minimum magnetization capacitance is adequately supplied. The voltage control must not provide reactive magnetization of the induction generator [12], [13], but the voltage control must be responsible for the reactive power demand that the isolated load requests.…”
