基于告警信息的保护跳闸识别方法研究

Ｒesearch on Protection Tripping Identification Method Based on Alarm Signal

摘要:

针对目前保护跳闸事件发生后主要依靠人工梳理告警信号来识别事件类型和漏发信号费时费力的问题,提出了构建保护跳闸序列比对模块。首先,构建了各类保护跳闸事件的标准序列模板;然后,设计了序列比对算法,实现了待匹配序列与标准序列模板的对比;最后,输出事件类型和漏发信号。通过算例证明了方法的有效性,同时进行了模块的设计与实现,通过实用化证明了该方法的准确性和快速性。

Abstract:

: Nowadays，after the happening of protection tripping event，it mainly depends on the manual sorting of alarm signals to identify the event type and missed signals，which is resulting in the wasting of time and labour． In order to solve this problem，a comparison module of protection tripping sequence is proposed． First of all，the standard sequence models for various protection tripping events are constructed，and then，a sequence alignment algorithm is designed which realizes the comparison between the matching sequence and the standard sequence model． Finally，the event type and missed signals are output． The effectiveness of the proposed method is demonstrated by numerical examples，meanwhile the modules are designed and implemented，and the accuracy and rapidity of the proposed method are proved by practical application．
