What is IEC 61850?

IEC 61850 is an international standard specifically designed for communication protocols within electrical substation automation. Its primary focus is on enabling interoperability between different devices and systems used in substations and power plants, facilitating efficient and reliable communication.

The standard provides a framework for the exchange of data between various equipment, such as protection relays, control systems, and measurement devices. By adopting a common data model and standardized communication methods, IEC 61850 ensures that different manufacturers' devices can work together seamlessly, improving system integration and reducing operational costs.

The emphasis of this standard on communication protocols distinguishes it from other options that pertain to safety, regulatory guidelines, or specific equipment types. It plays a crucial role in the modernization of grid management and smart grid technologies, enabling more sophisticated monitoring, control, and automation functions in electrical systems.
