摘要：This paper presents a comprehensive review and performance investigation of
Neutral Point Clamped Converter (NPCC) based Unified Power Quality Conditioner
(UPQC) by using Artificial Intelligent (AI) techniques. A Novel application of
various levels of Diode Clamped Multi-Level Inverters [DCMLI] with Anti Phase
Opposition and Disposition (APOD) Pulse Width Modulation (PWM) Scheme to
Unified Power Quality Conditioner (UPQC). The Power Quality problem became a
burning issues since the starting of high voltage AC transmission system. Hence, in
this article it has been discussed to mitigate the PQ issues in high voltage AC
systems through a three phase four wire Unified Power Quality Conditioner (UPQC)
under non-linear loads. The emphasised PQ problems such as voltage and current
harmonics along with voltage sags and swells have also been discussed with improved
performance. Also, it proposes to control the DCMLI based UPQC through
conventional control schemes. Thus application of these control technique makes the
system performance in par with the standards and also compared with existing
system. The simulation results based on MATLAB/Simulink are discussed in detail
to support the concept developed in the paper.
