【摘要】：传统的特高压直流输电系统一般在换流站交流网侧布置滤波兼无功补偿装置.为了避免谐波对换流变压器的不良影响,本文提出了一种滤波绕组并联的感应滤波换流变压器的谐波抑制方法,文中描述了其接线方案,解释了其滤波机理,并与传统的滤波方案进行了对比分析.以酒泉-湖南的±800kV特高压直流输电的工程参数为依据,搭建了所提滤波方案和传统方案的仿真模型.两个模型的阀侧和网侧电流的对比分析证明,新型谐波抑制方法效果良好.
[Abstract]:The traditional UHV HVDC transmission systems generally arrange filtering and reactive power compensation devices on the AC network side of the converter station. In order to avoid the adverse effects of harmonics on converter transformers, In this paper, a method of harmonic suppression of induction filter converter transformer with parallel filter windings is proposed. The connection scheme is described, and the filtering mechanism is explained. And compared with the traditional filtering scheme, based on the engineering parameters of 卤800kV UHVDC transmission in Jiuquan-Hunan province, The simulation models of the proposed filtering scheme and the traditional scheme are built. The comparison and analysis between the valve side and the grid side of the two models show that the new harmonic suppression method is effective.
