HV Substation Automation System with Modbus RTU, IEC 60870–5- 104 and DNP3Thailand
- Project start: October 2013
- Project completion: Under implementation
- iGrid products involved: iControl – Substation Edition, iRTUe and iRTU
- Number of RTUs/MV substations: 5 during 2014
- Number of data points: Up to 2000 I/O points per substation
- Protocols: IEC60870‑5–104, DNP3.0 and ModbusRTU
The iControl SCADA software, iRTU and iRTUe units have become the standard infrastructure for the substation automation systems (SAS) of a Thai utility, responsible for power generation and transmission in the entire country.
All iGrid products communicate with three different IEC60870‑5–104 control centers, each one with a redundant communication link. The data is collected from the iRTUe and sent directly by the iRTUs.

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
