IEC61850 protocol converter is a kind of protocol converter which converts the traditional power communication protocol into IEC61850 standard. This protocol converter can realize the interoperability and correlation between devices with different communication protocols in power system. This device has the advantages of small size, less space occupation and low cost.

IEC61850 provides a unified standard for substation automation and realizes seamless access between different intelligent devices. IEC61850 standardizes data naming, data definition, equipment behavior, equipment description characteristics and general configuration language, which makes information sharing and interoperability between different intelligent electrical equipment possible. The design of the specification adopts the object-oriented design method, and the hierarchical data structure makes the data maintenance simple and clear.

The support of IEC61850 protocol has become the mainstream choice of domestic secondary equipment manufacturers, because in the future of China's intelligent power system, IEC61850 will be a basic communication protocol. If the equipment does not support IEC61850 communication protocol, it can not be used in intelligent digital substation. The development trend of such manufacturers will be greatly restricted. In such a fierce market competition trend, it may even be eliminated by the market.

IEC61850 will also be able to support services such as IEC 61850, which will be able to support services such as alarm services and services. This method is to load the IEC61850 protocol converter board into the conventional secondary equipment, which is fast.
