What is the IEC 61850 standard?


What is the IEC 61850 standard?

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.

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.

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.

What is difference between GOOSE and MMS?

GOOSE messages use the MAC layer to transfer a control dataset between IEC 61850 devices in a one-way transmission, as shown in Fig. 3b. MMS messages use the TCP/IP protocol stack and operate in a client/server environment.

What is GOOSE and SMV?

1, SMV network is applied to the analog signal transmission between merging unit and protection, BCU on bay level, while GOOSE network is mainly applied to the transmission of binary messages like the tripping, on-off status, and switching, etc. of the devices on process level.

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.

What is MMS in IEC 61850?

IEC 61850 (IEC 61850 – Communication Networks and Systems in Substations) standard defines MMS protocol (Manufacturing Message Specification) as a server/client type communication.
