Medium Voltage Grid Automation RTUsArgentina
- Project start: April 2012
- Project completion: December 2012
- iGrid products involved: iRTU-B0D1
- Number of data points: Up to 450 I/O points/substation
- Protocols: IEC60870‑5–104
Prior to the project start, the customer (a distribution company in southern Buenos Aires, Argentina) had only been controlling its HV distribution grid remotely. At the end of 2010, the customer decided to extend its control to the 25kV MV distribution grid in order to improve the quality of service in southern Buenos Aires, an area with more than 2,500,000 customers and more than 6,000,000 people.
The project began in June 2011 with the goal of finishing the first phase of the project (control center in full operation) during the first half of 2012 and install another 150 RTUs at the end of 2012. Now, upon completion, iControl is controlling 4,000 RTUs from several manufacturers.
During the first phase of the project, RTUs of three different vendors were deployed, including iRTU-B0D1 units which were integrated in compact MV substations supplied by Ormazabal. The iRTU-B0D1 unit was connected to Ormazabal bay controller relay through a RS485 bus using the PROCOME protocol, thus allowing to control up to 8 MV feeder controllers.
External GPRS modems were used to communicate with the control center using the IEC60870‑5–104 protocol.

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
Medium Voltage Distribution grid automation
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 plant
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
