大型变电站远程监控系统的故障诊断

Fault Diagnosis of Remote Monitor and Control System of Large Power Station

随着信息技术的发展,许多电站都采用了远程监控系统,并在下层形成了许多中小型无人值守变电所。详细分析了测控系统在信息传递过程中,产生遥信误发、漏发和微机保护报文异常、丢失及死机等现象的原因,提出了相应的改进措施,对保证变电站的安全运行具有重要意义。

Along with the information technical development,many power stations adopt remote monitor and control system,and the small scaled and unmanned value guards a substation in the bottom layer.Analyses in detail the reason of telesignal sending in error,leak and microcomputer protection report abnormality,lose and crash in power station measure to control equipment,and corresponding improvement measures are put forward.Practice shows that the measures have important meaning to the safe movement which promises a power station.
