Station communication

Operational information and controls are available through a

wide range of communication protocols including IEC 61850

Edition 2. IEC 61850-9-2 LE, IEC 60870-5-103. IEC

60870-5-104. Modbus® and DNP3. The Profibus DPV1

communication protocol is supported via the protocol

converter SPA-ZC 302. Full communication capabilities, for

example, horizontal communication between the relays, are

only enabled by IEC 61850.

The IEC 61850 protocol is a core part of the relay as the

protection and control application is fully based on standard

modelling. The relay supports Edition 2 and Edition 1 versions

of the standard. With Edition 2 support, the relay has the latest

functionality modelling for substation applications and the best

interoperability for modern substations. The relay supports

flexible product naming (FPN) facilitating the mapping of relay’s

IEC 61850 data model to a customer defined IEC 61850 data model.
