Abstract: Aiming at the simulation of communication network of digital substation, mathematical models applicable for OPNET communication simulation software were built based on the data flow analysis of three layers of digital substation, i.e., station layer, bay layer, and process layer; further, in order to fit into the requirements of OPNET, the communication network of digital substation was modeled from views of node, network and business, together with the OPNET configuration scheme. The results of real application of a substation in Shaoxing grid indicate the proposed model as well as the configuration methods are correct and effective.
