Research on Risk Transmission Process and Immune Strategy of Mine Electric Power Information Network

The power information network is becoming more and more important in the safe and efficient production operation of the mine power system. Meanwhile, the power information network may be subject to security risks, such as malicious virus attacks, which poses challenges to mine safety production. Based on the complex network theory, this paper proposes a complex network model of the power information network. Aiming at the possible attack risk of the power information network, the SIR epidemic model is used to analyze and research on the evolution process of the power information network risk. On this basis, two immunization strategies are proposed to suppress the continuous propagation of power information network security risks. The immunization process of the power information network is simulated to verify the significance of the immunization strategy in the process of power information network security risk transmission.
