Compared with the traditional communication protocol, the equipment information structure and interaction method based on the IEC61850 standard have undergone tremendous changes. To study the performance of different types of intelligent electronic equipment based on the IEC61850 standard for information interaction, the research and development of intelligent substation automation equipment and the communication network.

Due to the lack of a fully functional station control layer test system for comprehensive quantitative testing, it can no longer meet the needs of the smart substation station control layer test.
