Medium Voltage Distribution Grid Automation

The new big chal­lenge for grid automa­tion

Advantages of Our Solution

  • RTUs and Gatewayare 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. The iRTU and iGW 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.

iGrid T&D Medium Voltage RTUs are designed think­ing in:

  • Easy adap­ta­tion to dif­fer­ent com­mu­ni­ca­tion media (built-in GPRS or PSTN modems are avail­able)
  • Massive, fast, and reli­able deploy­ment
  • Use of stan­dard com­mu­ni­ca­tion pro­to­cols (IEC60870‑5–101, IEC60870‑5–104, DNP3.0 and Modbus)
  • Remote main­te­nance and upgrad­ing
  • Rugged design to endure any envi­ron­men­tal con­di­tion
  • Wide power sup­ply range


While iControl Control Center edi­tion is pre­pared for:

  • Controlling thou­sands of RTUs, feed­ers and trans­form­ers
  • Operating the grid eas­ily and reli­ably
  • Allowing mul­ti­ple archi­tec­tures to be adapted to each util­ity need, from stand-alone sys­tems to redun­dant schemas with mul­ti­ple remote clients

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
