Reliability Test Method of Nuclear Power DCS Network Communication Based on Fault Injection

In order to improve the communication reliability of nuclear power DCS system and avoid the hidden fault-tolerant design Defect left over to the commercial operation stage of units. In this study, the reliability test method of nuclear power DCS network communication based on fault injection technology is adopted, and faults are injected in physical layer and link layer according to different fault modes. By using this method, DCS network communication failure mode of Nuclear Power Plant in Validity can be realized.
