摘要
为了改善继电保护故障信息系统通信效率,提高通信可靠性,在分析了继电保护及故障信息系统(以下简称保信系统)通信现状的基础上,提出一种保信系统在线通信报文分析方法。通过在线监视保信系统主站与子站之间通信,实时分析通信过程中的报文问题,判断通信异常出现的原因,对异常现象提出解决方案。现场运行结果表明,所提出的这种在线通信报文分析系统能够实时发现和分析系统中存在的问题,能够帮助保信系统提高通信质量。
In order to improve the communication efficiency and stability of protection relay fault information system （hereinafter referred to as PRFIS）, based on the analysis of current situation ofPRFIS, this paper puts forward a method of online communication message analysis for PRFIS, via monitoring of communication messages between master station and slave station, analyzing the error of messages, obtaining the reason that causes the error, and raising the way to correct the error. After a period of trial operation, it has been found that the online communication message analysis system can find and analyze some errors of PRFIS, accordingly it improves the communication quality of PRFIS.
