| Abstract: |
| The introduction of intelligent substation process-level network results in the great changes in the data source and transmission mode of relay protection. Its operation performance and reliability depend increasingly on the communication network. The data flow of relay protection and the communication mechanism of its messages are analyzed and the process-level network and IED devices are modeled based on IEC61850 by OPNET. The whole process simulation of relay protection in intelligent substation is implemented，including MU data acquisition，SV messages，GOOSE messages，protection algorithm and protec-tion output. With the current protection as an example，the principle and implementation of modeling and simulation are introduced and its feasibility and validity are verified，which provides an effective tool for quantitative analysis of relay protection in intelligent substation. |
