Problems solved by technology
[0003] In related technologies, BFT (Byzantine Fault Tolerance, Byzantine Fault Tolerance) type blockchain consensus mechanism is mainly used for power data consensus in multi-site fusion, such as PoW (Proof of Work, proof of work), PoS (proof of stake, proof of equity) , DPoS (Delegated proof of stake, share authorization certification mechanism), PBFT (Practical Byzantine Fault Tolerance, Practical Byzantine Fault Tolerance), etc. However, the BFT blockchain consensus mechanism is ineffective for nodes that initiate malicious attacks in a multi-station integrated power network. Responding in a timely manner can easily cause potential safety hazards and cannot ensure the security of power data for multi-station integration

The invention provides a multi-station fusion electric power data consensus method and device based on a PBFT block chain technology; wherein the method comprises the steps: firstly obtaining an alliance chain of a multi-station fusion electric power network, the alliance chain comprises at least one block chain of the multi-station fusion electric power network, and the block chain comprises a consensus node, an alternative node, and a common node; then, dynamically changing the consensus nodes of the block chain in the alliance chain to obtain dynamically changed consensus nodes; and carrying out multi-station fusion power data consensus according to the dynamically changed consensus node. According to the method, the block chains of the multi-station integrated power network form the alliance chain, and the consensus nodes in the alliance chain are adjusted by adopting a dynamic change mechanism based on the PBFT block chain technology, so that malicious nodes are prevented from serving as the consensus nodes to perform data consensus, and the security of multi-station integrated power data is guaranteed.
