Performance of active power line conditioner for loss reduction in the power distribution system

This paper deals with active power line conditioner (APLC), which is based on integration of series and shunt power converters sharing a common DC link. The parameter influencing supply reliability can be resulted by interruption of supply and may be solved by feeding from two sides for sensitive load power loss reduction can be proposed at the looped distribution system and also multi parallel transformers. In this paper the main purpose of series power converter of APLC is to control of power flow in order to reduce losses of looped distribution system. The aim of shunt inverter is to compensate for reactive power and current harmonics caused by nonlinear load. Simulation results, carried out by PSCAD/EMTDC, show that the proposed configuration can effectively reduce power losses and eliminate harmonic currents in distribution system for sensitive nonlinear loads.
