The present work discuss the localization and coordinated operation of active power filters installed in a distribution power network. The localization problem is solved off-line for a given load variation scenario. The control of the current injected by the active power filter is solved on-line. In both cases the design solutions aim at reducing the total harmonic distortion below 5% and individual...
This paper presents an universal active filter for harmonic and reactive power compensation in single-phase system. It is a combined system of a series active filter and a shunt active filter without use of transformer. The proposed system is suitable for applications where the size is a critical factor. The model of the system is derived and it is shown that the circulating current is an important...
