Power Quality Improvement in Distribution System Using Unified Power Quality Conditioner (original) (raw)

Lecture Notes in Electrical Engineering, 2014

Abstract

ABSTRACT The major power quality issues are voltage sag, voltage swell and voltage harmonics in distribution system. These power quality issues are solved by custom power conditioning devices such as Dynamic Voltage Restorer (DVR), Distributed Static Compensator (DSTATCOM) and Unified Power Quality Conditioner (UPQC). This paper presents the ability of Unified Power Quality Conditioner to mitigate voltage sag, voltage swell and voltage harmonics in distribution system. UPQC is modeled in MATLAB_SIMULINK environment with Fuzzy Logic (FL), Neural Network (NN) controllers. The performances of UPQC with two controllers are compared.
