IEC61850 Client

Try out the online RTU configurator. It calculates it all, even the power consumption so you dont have to worry about it. Get a complete BOM list, and never forget anything.

KEMA Certified IEC 61850 Digital Substation

In the transition towards a smarter grid, the adoption of IEC 61850-based substation automation and control systems is among the most notable trends. Brodersen provides comprehensive RTU solutions that support IEC 61850 Edition 1 & Edition 2. This enables fast, reliable, and secure access to data and control over the substation. Log directly from within the RTU for enchanced protocol analysis using Wireshark. Brodersen RTUs support IEC 61850 Client & Server with GOOSE. 

IEC 61850 Client

The Brodersen IEC 61850 Client interface allows the RTU to connect with IEC 61850 devices (IEDs/Servers) and discover their list of logical nodes. RTU variables can be automatically generated from all/parts of the discovered data and used to map or translate the data for use with other protocols Рmaking it easy to consolidate data from multiple devices, and to provide HMI functionality.

Overview – creating an IEC 61850 client application

The slideshow below shows how an IEC 61850 client application is created and includes extracts from an example substation. 

1 - create an example 61850 Client Project
Add a new project in WorkSuite, then add the 61850 Client driver and add a Master Port (comms channel).
2 - query the server
After querying the server, select the variables and attributes of interest.
3 - large substations have multiple servers
The example here shows the RTU connecting with 17x IEDs/Servers. Logical devices within each server manage control, measurements and protection. This RTU has almost 4,000 variables connected via the IEC61850 client interface!
4 - project overview
This RTU application includes many logic programs and protocols to manage the substation. Protocols used include IEC61850 Client (with IEDs), IEC61850 Server (to the SCADA host - as consolidated data), DNP3 Master and Slave (to IEDs and other SCADA hosts) and Modbus (local HMI - Panel PC).

EC 61850¬†is an international standard defining communication protocols for¬†intelligent electronic devices¬†at¬†electrical substations. It is a part of¬† the International Electrotechnical commission’s (IEC) Technical Committee 57[1]¬†reference architecture for¬†electric power¬†systems. The abstract data models defined in IEC 61850 can be mapped to a number of protocols. Current mappings in the standard are to MMS (Manufacturing Message Specification),¬†GOOSE (Generic Object Oriented Substation Event), SMV (Sampled Measured Values),and soon to¬†Web Services. These protocols can run over¬†TCP/IP¬†networks or substation¬†LANs¬†using high speed switched¬†Ethernet¬†to obtain the necessary response times below four milliseconds for protective relaying.
