摘要

统一电能质量调节器(UPQC)是广泛应用于互联配电系统(IDS)的一种功能强大的补偿装置。它能够处理几乎所有类型的电能质量问题(PQP)。它是串联并联补偿(SSC)的结合。它采用与公用系统串联和并联两种变流器拓扑结构。传统的变换器是采用2电平电压源逆变器(2LVSI)设计的。针对2LVSI在高压条件下损耗大的问题，本文提出了一种基于多级逆变器(MLI)的中立点箝位(NPC)转换器拓扑结构用于UPQC设计。通过对2LVSI和基于NPC-MLI的UPQC的电压调节和谐波抑制的对比分析，验证了变换器设计的拓扑优势。

Comparative Analysis of Conventional and Neutral Point Clamped Converter Topology for UPQC

Unified Power Quality Conditioner (UPQC) is a very powerful compensating device widely used in the Interconnected Distribution System (IDS). It is capable of dealing with almost all type of Power Quality Problems (PQP). It is the combination of Series-Shunt Compensation (SSC). It employs two converter topology namely series connected and shunt connected with the utility system. Conventional converters are designed by employing 2-Level Voltage Source Inverter (2LVSI). The 2LVSI suffers from high loss under high voltage conditions, hence this paper proposed a Multi-level Inverter (MLI) based Neutral Point Clamped (NPC) converter topology for designing UPQC. The comparative analysis of 2LVSI and NPC-MLI based UPQC is presented for simultaneous voltage regulation and mitigation of harmonic to check the topological superiority of the converter design.
