变电站遥测数据频繁跳变分析与处理

Analysis and Processing of Frequent Jumps of Substation Telemetry Data

针对多座500 kV变电站遥测数据频繁跳变的故障,通过详细分析遥测数据上送机制,利用报文获取和分析手段进行故障定位,通过模拟现场环境的对比试验,确定出故障原因为远动装置双口RAM误码校验问题和测控装置软浮点值转换受中断影响问题,通过硬件更换和软件升级,实现了遥测数据频繁跳变的故障处理,保证了电网的安全稳定运行。

In view of the fault of frequent jumps of telemetry data in several 500 kV substations,the telemetry data transmission mechanism is analyzed in detail,and then the fault is located by means of message acquisition and analysis.By comparative tests under a simulated field environment,it is determined that the cause of the failure is the double port RAM error check of the remote operating device and the interruption of the soft floating-point value conversion of the measurement and control device.Finally,through hardware replacement and software upgrade,the disposal of faults of telemetry data frequent jumps is realized,which guarantees safe and stable operation of power grid.
