What is IEC 61850?

IEC 61850 is an international standard for the design and operation of substation automation and communication systems in the field of electric power generation, transmission, and distribution. The International Electrotechnical Commission (IEC) developed this standard to provide a common framework for the integration of various devices and systems within a substation and across different substations, enabling more efficient and reliable electrical power systems.

Key features and components of IEC 61850 include:

1. Data Models: IEC 61850 defines standardized data models and communication protocols for describing and exchanging information about power system equipment, such as transformers, circuit breakers, relays, and meters. These data models are based on the Common Information Model (CIM).
2. Communication Protocols: The standard specifies Ethernet-based communication protocols, including the Manufacturing Message Specification (MMS) and Generic Object Oriented Substation Events (GOOSE) for real-time data exchange. It also includes Sampled Measured Values (SMV) for transmitting high-speed sampled data.
3. Substation Configuration Language (SCL): IEC 61850 uses SCL to define and describe the configuration of substation devices and their communication relationships. This allows for consistent and automated configuration of devices and systems.
4. Logical Nodes: Devices in a substation are represented using logical nodes, each of which performs specific functions and provides standardized services. Examples include the protection and control logical nodes.
5. Engineering Process: IEC 61850 defines guidelines and processes for the engineering, configuration, testing, and maintenance of substation automation systems. These guidelines help ensure interoperability between devices from different manufacturers.
6. Interoperability: One of the primary goals of IEC 61850 is to enable interoperability between devices and systems from different vendors. This helps utilities choose the best components for their needs and avoid vendor lock-in.
7. Cybersecurity: The standard includes provisions for securing communication and data exchange within substation automation systems, which is crucial in protecting critical infrastructure from cyber threats.

IEC 61850 has become widely adopted in the electric power industry because it simplifies the integration of various devices and systems, reduces engineering and maintenance costs, and enhances the reliability and flexibility of power system operations. It plays a significant role in modernizing and improving the efficiency of electrical grids and substations.
