Substation Automation

Substations are the most critical part of a power grid

Advantages of our solution

  • Great flexibility and adaptability to the requirements and operation modes of utilities.
  • Easy to use and easy to configure.
  • Supports all standard protocols: IEC61850, IEC60870-5-104, DNP3.0, DLMS, IEC60870-5-102, Modbus.
  • iRTU devices can be used as substation gateways, RTUs or BCUs (Bay Control Units).
  • iControl is an easy-to-use substation SCADA able to work in standalone, client/server or redundant modes.

Solution description

Substation automation represents one of the basis of the Smart Grids definition, as a key point on controlling the distribution network, hence the complete grid stability.

Grid automation evolved immensely in the past decade, from the old centralized RTUs based on big I/O quantities to the newest distributed IEC61850 systems which definitively introduce IP technology on the substations.

But the newest technologies must coexist with the oldest ones in order to retrofit the old substations step by step

iGrid T&D solutions are designed for both, new substations and retrofitting projects; i.e, projects where old substation automation systems should be connected to newer control centers with IEC60870-5-104 or DNP3.0 over TCP, or where new IEDs should be added (like IEC61850 protection relays).

Substation Automation Products

iGW-S Substation Gateway

Powerful and reliable substation gateway that supports most standard protocols such as IEC60870-5-101/104, DNP3.0, and IEC61850. It is equipped with an embedded Ethernet switch.


Smart, modular, and scalable BCUs (Bay Control Units) which support standard protocols including IEC61850, IEC60870-5-104, DNP3.0, Modbus, DLMS, etc. Available with internal I/O modules (iRTU-B series).

iControl Substation SCADA

High-performance SCADA for visualization and control of substation data. It is able to run either in Client/Server or Standalone modes, with advanced functionalities such as hot-standby redundancy, automatic line coloring, events notification (via e-mail and sms), SQL logging, and reports generation.
