Abstract
Induction generators are widely used in small hydro or micro hydro power. The induction generator has a low power factor because it is an inductive load and requires reactive power required for the rotating magnetic field. Since this reactive power is not generated by itself, it must be supplied from the power source. Since most of the reactive power is provided from the power supply side, the power factor is lowered. Capacitors are added to the generator terminals to easily compensate for the lowered power factor. Inrush current occurs when an induction generator is connected to the grid. In some cases, a reactor is added to the capacitor as part of a method to reduce this inrush current. The reactor is usually connected to the generator line to reduce the inrush current, but there are cases where it is also attached to the capacitor along with the harmonic current reduction.BRIn this study, changes in inrush current, voltage drop, power and power factor were analyzed depending on whether or not a capacitor was installed and a reactor was installed on the capacitor when the induction generator was started directly and connected to the grid.
