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