Abstract

The invention relates to the technical field of industrial big data, in particular to an emergency plan simulation method and system based on digital twinning. The method comprises the following steps: firstly, acquiring node operation time sequence data, system load time sequence data and historical emergency plan simulation data of each node in an industrial system; according to the time sequence mutual information between the nodes and the time sequence mutual information between the nodes and the system load, obtaining a node correlation coefficient, and further comprehensively evaluating the importance coefficient of each node; and further acquiring an accident transmission index of each node based on historical emergency plan simulation data, then comprehensively determining a data synchronization frequency of each node, and synchronizing the data synchronization frequency to a digital twin system for emergency plan simulation. According to the method, data synchronization frequency derivation is carried out based on node importance, synchronous transmission of redundant data is reduced on the premise of meeting the basic requirements of emergency simulation, and the operation efficiency and stability of emergency plan simulation are improved.
