Substation Automation Fully Compliant with IEC 61850-3

Power utilities face a variety of challenges, which are influenced by factors such as technological advancements, regulatory changes, environmental concerns, and shifts in energy demand. 


IEC 61850-3 Ethernet switches offer power plants a robust and reliable communication infrastructure tailored to the specific needs of the energy sector. These switches enhance network performance, security, and interoperability while enabling efficient remote management and future scalability, which contributes to the overall resilience and operational efficiency of power generation and distribution facilities.

About IEC 61850 Substation

IEC 61850 is a substation automation standard for electric power systems. The IEC 61850 standards have been expected to ensure seamless communication and integration among IEDs from different manufacturers at a hierarchical level. A key focus of the standards lies in its transmission protocols tailored for distinct data transfer requirements.

Feature Highlight

Built-in MMS Server


The MMS is based on IEC 61850-90-4 switch data modeling for power SCADA. Through MMS, administrators possess the capability to monitor and control IEDs, switches, as well as other MMS supported devices in substations.

IEEE 1588 V2


Precise time synchronization is essential within a substation to guarantee the synchronized operation of measurement devices linked to the power grid. The precision of these clocks can range from milliseconds to microseconds, contingent upon the specific application.


Packet Priority: IEC 61850 QoS


Substation automation devices are required to establish flawless communication for IEC 61850 multicasts, placing the utmost importance on prioritizing these transmissions. By giving precedence to the transmission of GOOSE/SMV packets, we ensure the seamless reception of these messages.

HSR/PRP Protocols for Zero Recovery Time


Compliant with IEC 62439-3, a pluggable module equipped with HSR/PRP protocols, is designed to fit the IEC 61850-3 modular switch RGS-P9000/PR9000 series. The HSR and PRP protocols provide seamless failover from a single point of failure. 


Power Utilities Application

Industrial Ethernet managed switches offer users possibility to draw maximum benefits from IEC 61850-3.  Many of our industrial switches are tailor-made for applying in substation automation system and also support the IEEE 1588v2 standard (PTPv2). The IEC 61850-3 standard is not just the Ethernet-based substation automation protocol but serving the whole solution of power networks.
