摘要

基于模块化多电平换流器(MMC)的统一潮流控制器(UPFC)是当前最新型的柔性交流输电技术，与柔性直流输电中MMC交流电压在额定值附近不同，理论上UPFC串联侧MMC输出电压可在零到额定值之间任意可调，在调制比较小时，换流器输出电压中将含有较大的谐波成分。结合南京西环网UPFC实际工程，为研究基于MMC的UPFC对电网谐波的影响，从UPFC工作原理出发分析MMC谐波理论计算方法及分布特性，给出了UPFC接入系统后电网谐波的计算公式，用于评估系统各种运行方式下UPFC在不同子模块数量及电压调制比下的谐波特性及其对电网电压谐波的影响，为工程设计和系统运行维护提供依据。最后，理论计算和仿真结果验证了所提出的谐波分析计算方法的有效性。

Abstract

The modular multilever converter (MMC) based unified power flow controller (UPFC) is the newest flexible AC transmission system (FACTS) technology at present. The output voltage of the series MMC in UPFC can be arbitrarily regulated from 0 to a rated value

which is different from the MMC based high voltage direct current (HVDC)-light with the AC voltage of MMC near the rated value in operation. As a minor modulating ratio of MMC

there may be a higher harmonic level of AC voltage. With respect to the actual UPFC project in the Western Grid of Nanjing

to study the impact of UPFC on the harmonic of power system

and by proceeding from the working principles of UPFC

an analysis is made on the harmonic calculation method and distribution characteristic of MMC. The formulas for calculating the harmonic of power network with UPFC interconnected are given for use in evaluating the influence of UPFC at different voltage levels and modular ratios

on power network harmonic in various operation modes to provide a basis for UPFC project design and operation. Finally

the effectiveness of the harmonic analyzing and calculating methods proposed are verified by theoretical calculation and simulation results. This work is supported by State Grid Corporation of China (No. SGCC-2015-011).
