IEC 61850 is an international standard that unifies communication protocols between different systems within a substation, such as protection, control, and measurement equipment. Specifically, it enables devices to quickly exchange data and status using GOOSE and SV via LAN without requiring separate links for each relay. IEC 61850 has become a globally adopted standard that spans a wide range of energy industries, facilitating proper infrastructure communications and interoperability.
Beyond the communication aspect, it also standardizes the modeling of the different functions to create a unified view of the whole substation.
