Research on Fault Recovery Mechanism of Power Information System Based on SDN

In order to improve the flexibility and reliability of the power information system and reduce the difficulty of troubleshooting caused by the improper operation of the information system, based on the current development of the power information system, combining the SDN network architecture and technical features, this paper analyzes the advantages of the SDN technology in the power information system. In addition, the active and passive fault recovery scheme based on SDN power information system is also designed and implemented. The experimental results show that the active and passive fault recovery scheme can realize the automatic restoration of faults in the power information system conveniently and cheaply, so it meets the dynamic recovery requirements of the power information system, provides a theoretical basis for the extensive application of the SDN in the power information system.
