Medium Voltage Distribution grid automation

The new big challenge for the grid automation

Advantages of our solution

  • RTU and Gateway devices are able to handle multiple communication protocols to main station/control center (IEC60870-5-104, IEC60870-5-101, DNP3.0, Modbus).
  • Ability to adapt to different communication media. iRTU and iGW products are available with built-in GPRS or PSTN modems.
  • iControl Control Center Edition is prepared to manage the communication and data sent by thousands of RTUs from different vendors.

Solution description

Once the transmission and HV distribution grids are automated, the next step to improve the grid performances and reduce dramatically the outages, is the medium voltage distribution grid automation, with levels ranging from 33kV to 6kV. But the medium voltage grid automation has represented a big challenge for many utilities, as it is less critical and huge, with thousands of substations, transformers and feeders.

The challenge is to find solutions adapted to more remote places with less prepared facilities (without temperature control and less maintenance), which should use communications networks with heterogeneous medias and lower performances (bandwidth, safety and reliability) compared to the ones used in the high voltage substations.

Medium Voltage Distribution Grid Automation Products

Medium Voltage RTUs

Intelligent, flexible and scalable RTUs (Remote Telecontrol Units) for MV grid automation. They can be equipped with built-in GPRS or PSTN modems, and support standard protocols including IEC61850, IEC60870-5-104, DNP3.0, Modbus, DLMS, etc.

iControl SCADA, Control Center Edition

iControl Control Center Edition is able to manage thousands of RTUs from different vendors, and to support multiple architectures in order to adapt to utilities requirements. iControl SCADA is available with advanced functionalities such as server redundancy, automatic line coloring, alarms notification via e-mail and/or sms, SQL logging, and reports generation.

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

Substation Automation

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

Smart metering

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

Protocol converter

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
