摘要
通过对一次保护动作行为分析,发现光差保护和高频纵联保护作为线路主保护这一配置方案下高频保护因延时而"拒动"的现象,进而以南瑞RCS-902A保护为例,对高频纵联保护在故障情况下的动作延时进行了详细的分析研究。建议在有条件的情况下,线路主保护避免采用此类保护配置方案。
With the analysis of a protection process, the malfunction of high frequency line protection was found out in the scheme that optical fiber differential protection and high frequency protection are configured as main line protections. And the delay of high frequency protection is analyzed and researched in detail in this paper. This line protection configuration is not suggested if conditions are provided.
