电力监控系统与五防系统故障问题分析处理

Analysis on the failure problems of the power monitoring system and five prevention system

变电站微机监控系统与五防系统在运行中常见的问题有遥信不对应、五防不能解锁监控操作、监控系统与五防通信中断等。为有效处理上述问题,需要熟知两者通信特点及通信规约。本文通过举例说明在处理这些常见问题过程中,分析通信报文能快速找出故障原因,并能及时有效的处理故障。因此,分析报文是处理这些常见问题的关键。

The common problem in the operation of the microcomputer monitoring system and five prevention system in substation including telecommand without correspondence, five prevention can＇ t unlock monitoring operation, monitoring system, five prevention com- munication interrupt and so on. To effectively deal with the problem that needed to be familiar with the communication characteristics and communication protocols. In this paper, through an example in the process of handling these common problems, analysis of the communication message could quickly find out the cause of the problem, and could be timely and effective treatment failure. Packet analysis was the key to deal with these common problems.
