IEC60870-5-104规约远动信息丢失异常分析及对策

Analysis and countermeasure on abnormal loss of remote information for IEC60870-5-104

介绍当前国内IEC60870-5-104远动规约应用中存在的异常情况,结合湖南500 kV电网集控自动化系统中IEC60870-5-104远动规约一次通讯异常案例,剖析出现该远动规约通讯异常的内在原因,提出相应解决对策。

Based on the abnormal application state of the current domestic IEC60870-5-I04 teleeontrol protocol, and eombined with an abnormal communieation case of IEC60870-5-104 protocol eentralized control for automation system in Hunan 500 kV power grid, the internal cause of abnormal teleeontrol communication is analysed and countermeasure is put forword in the paper. Actual tests show that the protocol communication abnormal is eliminated.
