On the basis of the characteristics of line boundary, this paper analyzes the different features of internal and external faults.
在线路边界频率特性的分析基础上,深入地分析了区内外故障时的特征差异:就某一类故障而言,区外故障时反行波中(阻塞频带内的)高频分量与(1-10kHz内的)低频分量的比值显著小于区内故障时的比值。
Then presents that the surge impedance of busbar capacitance and line trap is different from transmission line, and based on which proposes the concept ‘line boundary’.
为此从输电系统的频域模型着手,全面分析了输电线路、母线和阻波器的频率特性,指出母线对地等效电容和阻波器的阻抗显著地不等于线路的特性阻抗,由此提出“线路边界”的概念。
In the first part of the whole paper, the fault induced transients are analyzed making conclusions that the different character of transients between internal and external fault are controlled by reflection and refraction coefficient at line boundary.
在第一部分中 ,对故障产生的暂态进行了分析 ,发现区内外故障暂态分量的频谱差异主要与线路边界的折、反射系数的频谱有关。
