What is IEC 61850-9-1 Ed.10?

IEC 61850-9-1 Ed.10 is a technical standard for communication networks and systems in substations. It is part of the global standard developed by the International Electrotechnical Commission (IEC) for the automation of power generation, transmission, and distribution systems.

Understanding the Basics

The IEC 61850-9-1 Ed.10 standard provides guidelines and rules for implementing real-time communication between Intelligent Electronic Devices (IEDs) in substations. The standard ensures secure, reliable, and interoperable communication, ensuring that devices from different manufacturers can seamlessly work together.

The key feature of IEC 61850-9-1 Ed.10 is the Sampled Values (SV) and Generic Object-Oriented Substation Event (GOOSE) protocol. These protocols define the format and structure of data exchanged between IEDs. SV transfers analog values, such as current and voltage, while GOOSE facilitates the exchange of events and status information.

The Benefits and Applications

IEC 61850-9-1 Ed.10 brings significant benefits to the power industry. Improved interoperability reduces the complexity of substation automation systems, enabling easy integration of new devices and services. The standard supports the implementation of advanced features like automated fault detection, remote configuration and control, and faster system restoration.
