What is the IEC 61850 standard?
Table of Contents
IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations. It is a part of the International Electrotechnical Commission’s (IEC) Technical Committee 57 reference architecture for electric power systems.
What are the benefits of using IEC 61850 standard?
Major Benefits
- Eliminate Procurement Ambiguity.
- Lower Installation Cost.
- Lower Transducer Costs.
- Lower Commissioning Costs.
- Lower Equipment Migration Costs.
- Lower Extension Costs.
- Lower Integration Costs.
- Implement New Capabilities.
What is IEC 61850 and what are the aims of IEC 61850?
IEC 61850 is an international standard that defines communication protocols to provide communication between different equipment located in a substation, such as protection, control, and measurement equipment, as well as (IEDs) intelligent electronic devices.
What are the disadvantages of using IEC 61850 standard in substations?
The disadvantage of IEC 61850 for an electrical substation automation standard is the complexity of the initial research and development before implementing a complete system. Major advantages are the descriptive strings used naming every element, standardised object names are defined to relate to the data.
What is Goose IEC 61850?
GOOSE (IEC 61850) The GOOSE (Generic Object Oriented Substation Event) protocol is a communication model defined by the IEC 61850 standard, which uses fast and reliable mechanisms to group any format of data (status, value) into a data set and transmit it across communication networks within 4 milliseconds.
Is IEC 61850 a protocol?
Where does the IEC 61850 protocol apply in a substation?
IEC 61850 defines a fast and reliable point to multi point message exchange procedurethat can be used to replace copper wiring using in the data exchange between the cabinets in a substation. These messages are called GOOSE – Generic Object Oriented Substation Event.
How many application layer protocols are defined by IEC 61850?

How does GOOSE messaging work?
GOOSE protocol is an event-based protocol. The concept of GOOSE communication is that the publisher periodically sends messages and when an event happens (ex. Trip, Contactor closed …), it sends a burst of messages with new data.
How does a GOOSE work?
GOOSE data is directly embedded into Ethernet data packets and works on publisher-subscriber mechanism on multicast or broadcast MAC addresses. GOOSE uses VLAN and priority tagging as per IEEE 802.1Q to have separate virtual network within the same physical network and sets appropriate message priority level.
