This paper deals with Minimum VA rating handled by a Unified Power Quality Conditioner, which consists of Series and Shunt Active Power Filter. The Series Active Filter is Dynamic Voltage Restorer (DVR), which regulates the voltage at the point of common coupling with minimum VA loading. The Shunt Active Filter is Distribution Static Compensator (DSTATCOM) which compensates the reactive power and...
This paper presents the simulation of the unified power quality conditioner (UPQC) to mitigate voltage harmonics, voltage sag, voltage swell & current harmonics. The UPQC consists of series and shunt active power filter (APF), which are connected in cascade via a common dc-link capacitor. This paper presents the simulation is done for a three-phase UPQC working with unit vector template generation...
This paper describes a novel sliding mode method with the fuzzy controller approach in the development of unified power quality conditioner (UPQC) for reactive power, harmonics and both symmetric and asymmetric sag and swell compensation. The UPQC consists of both shunt and series converter having a common dc link. The shunt converter eliminates current harmonics generated from the nonlinear load...
This paper presents a novel control strategy for the case of 3-phase 3-wire Unified Power-Quality Conditioner (UPQC) based on the concepts of instantaneous active and reactive Power theory. The UPQCs is one of the major custom power solutions capable of mitigating the effect of supply voltage sags / swells, distortion, unbalance voltage at the point of common coupling (PCC) as well as load harmonics,...
A Unified Power Quality Conditioner (UPQC), which integrates shunt and series active filters, is a powerful tool to settle the power quality problems. In this paper analysis results of a combination the UPQC with the superconducting magnetic energy storage (SMES) are presented. The proposed scheme can compensate voltage sag, voltage interruption and harmonics at the point of common coupling (PCC)...
