This paper deals with the dynamic performance of a solar PV array integrated UPQC-P (SPV-UPQC-P) for use along with critical loads. The shunt compensator of SPV-UPQC-P is connected across the load and compensates for reactive power along with supplying the power from PV array into the grid. The series converter of SPV-UPQC-P compensates for the sags and swells in utility grid voltage. A suitable voltage...
Power quality has become an important factor in power systems, for consumer and household appliances with proliferation of various electric/ electronic equipment and computer systems. The main causes of a poor power quality are harmonic currents, poor power factor, supply voltage variations, etc. In recent years the demand for the quality of electric power has been increased rapidly. Power quality...
This paper evaluates the effect of unified power quality conditioner (UPQC) on transient performance of common-shaft cascade induction motors (CSCIM). This system is commonly used in deep well digging plant (i.e. oil wells). This paper also introduces novel functionalities for UPQC (e.g. it protects the cascade scheme from supply voltage sag and swells and provides a controllable power factor condition)...
