摘要

针对直流输电系统主回路中平波电抗器电感值的选择原则及方法进行了相关研究。首先引入电流斜率系数

用以衡量平波电抗器抑制故障电流上升的效果

并推导出故障期间直流电流随电流斜率系数变化的关系。通过分析平波电抗器电感值选择时应考虑的主要制约因素

按系统发生扰动时抑制直流电流上升速度和避免轻载时直流电流断续的要求

得出用于初步选择平波电抗器电感值的综合公式。最后

以葛南直流输电工程为例

验证了所提出的参数选择方法的合理性。

Abstract

Relevant research is carried out on selection of the smoothing reactance for HVDC projects.The concept of current slope factor is introduced to measure the effect of inhibiting fault current rising by smoothing reactor.And the relationship of DC current versus current slope factor during the course of fault is derived.Next

an integrated expression is deduced for selecting the reactance of the smoothing reactor by analyzing the main restrictions on the smoothing reactance.Finally

the proposed principle for parameter selection is verified in Ge-Nan HVDC project.
