ABB Relion® Protection and Control REX640 Station communication

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.

The IEC 61850 communication implementation supports

monitoring and control functions. Additionally, parameter

settings, disturbance recordings and fault records can be

accessed using the IEC 61850 protocol. Disturbance

recordings are available to any Ethernet-based application in

the standard COMTRADE file format. The relay supports

simultaneous event reporting to five different clients on the

station bus.

The relay can send binary and analog signals to other devices

using the IEC 61850-8-1 GOOSE (Generic Object Oriented

Substation Event) profile. Binary GOOSE messaging can, for

example, be used for protection and interlocking-based

protection schemes. The relay meets the GOOSE performance

requirements for tripping applications in distribution

substations, as defined by the IEC 61850 standard (class P1.

<3 ms data exchange between the devices). The relay also

supports the sending and receiving of analog values using

GOOSE messaging. Analog GOOSE messaging enables easy

transfer of analog measurement values over the station bus,

thus facilitating, for example, the sending of measurement

values between the relays when controlling transformers

running in parallel.
