The application of IEC61850 standard in the online monitoring system of the smart substation

This paper discussed the application of online monitoring system based on IEC61850 standard in the smart substation. Firstly, the functions and performance requirements of online monitoring system have been discussed, and the functional model and interface model of online monitoring based on IEC61850 have been established; Secondly, the application schema of online monitoring system has been designed for smart substation. Furthermore, according to the practical application in the pilot project, the validity of the models and the schema has been verified, and a summary of the application has been given.
