Grid Message Security Recognition Method Based on Rule Self-learning

Power grid message has become the basic carrier of information transmission in smart substation. In the face of the ever-occurring threat of power network information security, the security of power network message is becoming increasingly important. In view of the fact that traditional message recognition methods cannot adapt to complex and changing grid messages, this paper proposes a rule-based self-learning method for grid message security identification. Firstly, this paper studies the information network of intelligent substation based on IEC61850 and the frame structure and flow characteristics of grid message. Then, it analyses the rule self-learning method of grid message recognition, and further introduces the specific implementation process of this method. Finally, a test platform is constructed to verify the effectiveness of the rule-based self-learning method for grid message security identification.
