摘 要: 对许多高压直流输电工程直流侧谐波的现场测试发现,现场测试的结果与采用传统的六脉波模型计算出的直流侧谐波有很大的差异。因而该文介绍了一种新的模型———三脉波模型,用于分析高压直流输电系统直流侧的谐波。采用三脉波模型分析而得的直流侧的谐波特性完全符合现场测试的结果。该文分析了该三脉波模型的特性,同时给出了基于三脉波模型的直流侧的滤波方案设计。 Measurements of the harmonics on the DC side in many HVDC projects have disclosed that considerable discrepancies exist between the results obtained with the traditional six-pulse model and the one on the spot. Thus a new model, three-pulse model, for analysing DC side harmonics is proposed. The real harmonic characteristics of the DC side fully accord with the results of the three-pulse model analysing. This paper presents the characteristic analysis of the three-pulse model as well as the filter scheme design of the DC side.
