摘要
背靠背高压直流输电（ＨＶＤＣ）系统已经在交流系统连网中得到了应用。在连接不同频率的交流网络时，它不仅存在通常ＨＶＤＣ系统的特征谐波、非特征谐波，还存在着间谐波。文章通过一个６脉波桥通用仿真模型的建立，采用时域离散分析（ＤＴＡ）方法对背靠背ＨＶＤＣ系统进行了稳态仿真研究，其结果是研究ＡＣ侧、ＤＣ侧谐波特性及其联系的基础。
Back to back HVDC system had been used to join AC systems. When the frequencies of the joined AC systems are different, there will be not only characteristic harmonics and uncharacteristic harmonics but also interharmonics. This paper gives a general simulation model of the 6-pules convertor ,and makes use of the method of descrite time domain analysis(DTA) for the study of steady state simulation of the back to back HVDC system.The result of this research is the base of the studing of performance and relationship of harmonics on AC side and DC side.
