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...
A control algorithm is proposed for a three-phase hybrid power filter constituted by a series active filter and a shunt passive filter. The control strategy is based on the dual formulation of the vectorial theory of electrical power, so that the voltage waveform injected by the active filter is able to compensate the reactive power, to eliminate harmonics of the load current and to balance asymmetrical...
