The transmission system is prone to data information loss during the operation and maintenance process,resulting in unstable data center network and insecure data architecture.The VL2 network architecture,through the coordinated recovery strategy,can adjust the data information in the network structure after being attacked by the network and cyber-physical,and eliminate the data that affects the cyber-physical coordination center of the power transmission system,thereby improving the network information security capability.At the end of the receiving equipment of the power transmission system,a CDR circuit model with a single-loop structure is applied,a half-rate type phase detector is used,and a data synchronization unit is added.The data center network ensures the fault tolerance of the information by backing up the data of the local copy in advance,using the improved Paxos consensus algorithm protocol for data recovery.The experiment results show that the data recovery efficiency of the data center network in this study is the highest,and the data recovery time is less than 250 s.
