摘要
通过故障实例分析,阐述了同杆并架线路之间的互感对零序功率方向元件故障判别的影响,以及跨线故障时影响线路保护的主要因素,并提出了解决这些问题的对策。
With the analysis of an actual fault, this paper expounds the influence of mutual inductance between lines on the same tower on fault identification of zero-sequence power direction component, analyzes the main factors affecting the line protection during overline faults, and offers solution to these problems
