High Voltage Substation RTU with Modbus RTUMiddle East
- Project start: October 2012
- Project completion: May 2013
- iGrid products involved: iRTU-B0C1; iRTU-D1R1
- Number of RTUs/MV substations: 5 units centralized in one Cabinet
- Voltage level: 63/20kV
- Number of data points: Up to 450 I/O points/substation
- Protocols: IEC104, DNP3.0, Modbus RTU
The end customer of this project is as a huge shipbuilding company, which is responsible for the manufacture and maintenance of oil and gas tankers in the Persian Gulf. The required electric energy is supplied by a 63/20 KV substation installed in the main yard.
The HV element of the substation is monitored and controlled by the regional utility control center via DNP3.0, and the MV element is monitored and controlled by a local operator. The installed RTU from iGrid (iRTU-B0C1) reads the metering data from metering IEDs in Modbus RTU, transferred via an RS485 bus.

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
