Medium Voltage Grid Automation with IEC 104Spain
- Project start: June 2012
- iGrid products involved: iRTU-B0D1
- Number of RTUs/MV substations: 4 MV substations
- Number of data points: Up to 450 I/O points/substation
- Protocols: IEC60870‑5–104
iRTU was chosen by one of the most important Spanish electrical utilities to be used in a field test of IEC60870‑5–104 RTUs with GPRS routers. The iRTU-B0D1 model was used to control compact MV substations by Ormazabal.
The iRTU-B0D1 unit was connected to an Ormazabal bay controller relay through an RS485 bus using the Procome or Modbus RTU protocols. This allowed controlling up to 8 bays per substation.

More solutions for smart grids, substations and energy plants
iGrid T&D’s SCADA, RTUs, substation gateways, protocol converters and bay controllers support both IEC61850 client and server communication capabilities. When acting as IEC61850 servers, our solutions are able to map any existing IED to IEC61850 logical devices
IEC61850, IEC60870‑5–104 and DNP3.0 (as well as other communication protocols) are used worldwide for substations’ automation. iGrid T&D solutions use all of them to have a completely interoperability with any other vendor
Our solutions fulfill the standards required by electrical companies for the control of Medium Voltage grids (MV/LV substations). Our devices are capable to adapt to different communication media (e.g. serial, Ethernet, GPRS/3G, PSTN) and able to handle multiple communication protocols (e.g. IEC60970‑5–104, DNP3.0)
Our smart metering solutions support the most popular metering protocols (IEC60870‑5–102, Modbus and DLMS) and multiple communication media. iGrid T&D is working with the most important meter manufacturers worldwide to collect and deliver metering information to the electrical market
Retrofitting electrical facilities means to use the newest devices together with the oldest ones. For these projects, flexible and adaptable protocol converters are vital devices.
Hydroelectric generation plants require remote control following the electrical systems standards, but a higher degree of automation is requested, as special procedures are requested for actions like dams open/close, generator start/stop, etc. iGrid solutions will give you easy tools to automate small and big hydroelectric generation plants
