The introduction of intelligent substation process layer network has caused great changes in the data source and transmission method of relay protection, and its action performance and reliability are increasingly dependent on the communication network. The data flow of the relay protection in the intelligent substation and the communication mechanism of each message are analysed. Based on the IEC61850 standard, the process layer network and the relay protection IED device are modelled on the OPNET simulation software to realize the MU of the relay protection in the intelligent substation the whole process simulation of data collection, SV message, GOOSE message, protection algorithm and protection export. Combined with the example of current protection, the principle and realization mechanism of modelling and simulation are explained, and its feasibility and effectiveness are verified, which provides a new effective research tool for the quantitative analysis of relay protection in smart substations.
