"The project aims at the comparative analysis of different power theories (IRP, SD, etc.) developed within the period of several last years, especially those, which are connected with control method of shunt and series active filters. In addition to that, new modifications of the power theories will be search for. The performance criteria of the existing and new methods will be evaluated with respect to the ability of the active filters to compensate high harmonics and reactive powers, and to the distribution of line losses produced. Appropriate power theories will be proposed for the different functions of pulse-controlled rectifiers and types of the active filters."@en . . . . . " voltage inverters" . "5"^^ . " power losses" .
