| Abstract |
Among the loads used by the customers, there are linear loads such as electric lamps and heat, and nonlinear loads such as converters and inverters. In a typical linear load, an inductive load has a low power factor, so a capacitive load such as a capacitor is used to improve the power factor. For nonlinear load such as power converters, harmonics components are a problem and need to be reduced. When the passive filter is used to reduce harmonics of a particular order current, the capacitor has a component that makes the phase of the current precede the phase of the voltage, so that the power factor can be preceded. If the power factor closes to unity, but it becomes a problem if it becomes a negative area.
In this study, we analyze how the power factor is changed by parameter change of passive filter installed to reduce the harmonic current of a particular order when three-phase nonlinear is used. |
