IEC61850 is a communication protocol used in power automation systems, defining standardized communication and data models to support data exchange and interoperability between devices and systems. The protocol is widely applied in power system automation and digital transformation, especially in smart grids and distributed energy resource management. Its main features include standardization, flexibility, scalability, efficiency, and security. IEC61850 protocol communication solutions have been implemented based on various processor platforms, reducing development difficulty and R&D time.

What is the IEC61850 Protocol?

IEC61850 is a communication protocol used for data exchange and control in power automation systems. It defines a standardized communication and data model to support data exchange and interoperability between devices and systems.

The IEC61850 protocol is widely applied in power system automation and digital transformation, particularly in smart grids and distributed energy resource management. By using the IEC61850 protocol, power system components can communicate with each other more efficiently, enabling more precise monitoring and control.

The IEC61850 protocol application framework diagram is shown below:

Figure 1

The service implementation of the IEC61850 standard is mainly divided into three parts: MMS services, GOOSE services, and SMV services.

MMS services are used for data interaction between devices and the backend.
GOOSE services are used for communication between devices.
SMV services are used for sampled value transmission.

The relationship between the three services is shown in the figure below:
