The invention belongs to the technical field of
power system automation, and particularly relates to an intelligent substation
secondary circuit modeling method and a related device. The intelligent substation
secondary circuit modeling method comprises the steps that based on constructed elements, the relation between the elements is defined in a hierarchical mode, and a model for fusing a physical circuit and a logic circuit is constructed and obtained and serves as a
secondary circuit model; when the relation between the elements is defined in a hierarchical mode, the substation module serves as the root of the
secondary loop model, the subnet module is arranged below the substation module, the secondary equipment modules are arranged below the subnet module, the secondary equipment modules are connected through the port module, and data interaction is carried out through the
data set module. According to the method, the bidirectional fusion model of the physical loop and the logic loop is established, information inconsistency of the bidirectional relation is avoided, and the actual requirements of an existing intelligent substation can be met.
