What is IEC 61850??

IEC 61850 is the established standard for communication?in substations. The devices in such systems are IEDs?(Intelligent Electronic Devices). IEDs use standardized?communication to share information with each other,?even if they are from different vendors. For the different?types of communication, the following services are?utilized:?

C/S (Client/Server) for direct communication between?two devices, where one acts as a server and one as a?client – a typical application is a report from an IED to the?HMI (Human Machine Interface). This communication?is defined in IEC 61850-8-1 as MMS (Manufacturing?Messaging Specification).?

GOOSE (Generic Object Oriented Substation Event) for fast?transmission of events such as protection trips. Sent out?as multicast (one-to-many) GOOSE is also typically applied?for interlocking.?

SV (Sampled Values) to transmit measured values from?measurement transformers (“Merging Units”) to the?substation network. Sent out as multicast.?
