The invention relates to the technical field of power
system dispatching data networks, and discloses a reliability evaluation method based on a dispatching data
network topology structure, and the method comprises the steps: S1, abstracting a dispatching data network into a
network topology model composed of nodes and edges, assigning attributes such as equipment type,
failure rate, node stability and service
bearing capacity to the node, and assigning attributes such as link bandwidth,
delay and edge stability to the edge; s2, analyzing different services borne in the data network, and determining the importance of each service; according to the method, a complex scheduling data network is abstracted into a
topological graph model, core nodes, aggregation nodes and access nodes are accurately divided, reliability attributes are given to the nodes according to equipment performance parameters and redundancy configuration conditions, meanwhile, transmission stability indexes of edges are quantized in combination with link
bandwidth utilization rate, physical medium types and other elements, and the reliability of the nodes is improved. And finally, comprehensively analyzing the scheduling data network to obtain a reliability index.
