IEC61850 is a complete communication standard system for substation automation system. Compared with the traditional communication protocol system, IEC61850 communication protocol has outstanding characteristics in technology: using object-oriented modeling technology; using distributed and layered system; using abstract communication service interface and special communication service mapping SCSM technology; using MMS technology; Interoperability; having future oriented and open architecture.

Digital substation can be regarded as the intermediate transition state from traditional substation to intelligent substation. Based on IEC61850 standard intelligent electronic equipment and electronic transformer, it promotes the digital transformation of substation. The purpose of using IEC61850 standard is to realize interoperability and information sharing between intelligent electronic devices of different manufacturers in substation through a protocol.

IEC61850 protocol converter is a special solution for intelligent devices that can not meet IEC61850 standard to enter digital substation and smart grid.

Protocol converter can appear in the form of plug-in, each plug-in corresponds to a protocol, which fully ensures the processing capacity of Guiyue, and also has the characteristics of flexible expansion and convenient maintenance. Each protocol converter has four ports, including three Ethernet ports and one non Ethernet port. The functions and parameters of each port are configured by configuration software.
