摘要
从零序有功选线的基本原理出发,结合对现场实际数据的分析,阐述了作为线性变换的对称分量法用于分析具有很强非线性过程的单相接地故障的局限性。在客观地分析了零序有功选线优缺点的基础上,提出了一种实用的单相接地故障事故处理方法。
Combining the analysis of field data with the basic principle of fault line selection based on zero sequence active power,this paper expatiates on the limitations of symmetrical-component method.As a linear transform,this method has its limitation when used to analyse single phase grounding fault with very strong non-linear process.Through an objective analysis of the advantages and disadvanges of fault line sclection based on zero sequence active power,a practical solution to single phase grounding fault is proposed.
