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 – making 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.
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 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.
