A review and performance investigation of NPCC based UPQC by using various artificial intelligence techniques

الملخص EN

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.
