Intelligent Substation Industrial Ethernet Technology Solution
2025-09-28
A digital/smart substation is built upon intelligent primary equipment and networked secondary devices, leveraging the IEC61850 communication protocol. The IEC61850 standard divides the substation’s communication architecture into three layers: the process layer, the bay layer, and the station control layer. High-speed network communication is employed both within each layer and between them.
The substation’s overall communication network can be further categorized into two key components: the station control layer communication network, which connects the station control layer with the bay layer, and the process layer communication network, linking the bay layer with the process layer.
This advanced substation design enables seamless information sharing and interoperability among smart electrical devices, paving the way for a modernized power infrastructure.
