Is IEC 61850 a protocol?
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 is MMS protocol in IEC 61850?
IEC 61850 MMS (Manufacturing Message Specification) is a client/server based protocol for communications between IEDs (IED – Intelligent Electronic Device) and higher level entities (such as RTUs and SCADAs) over Ethernet that is part of the IEC 61850 standard for communication technology in substations.
What are the objectives of IEC 61850?
The objective of IEC 61850 is to dramatically improve device data integration into the information and automation technology, reducing the costs for engineering, commissioning, operation, monitoring, diagnostics, asset management, and maintenance and increasing the agility of the whole life cycle of a substation.
What is difference between MMS and Goose?
GOOSE messages use the MAC layer to transfer a control dataset between IEC 61850 devices in a one-way transmission, as shown in Fig. MMS messages use the TCP/IP protocol stack and operate in a client/server environment.
What are the benefits of using IEC 61850 standard?
The increasing application of intelligent electronic devices (IEDs) with International Electrotechnical Commission (IEC) Standard 61850 capacities provides interoperability and advanced communications capabilities in substation protection, coordination, control, monitoring, metering, and testing.
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 the reference architecture for IEC 61850?
IEC 61850. It is a part of the International Electrotechnical Commission’s (IEC) Technical Committee 57 reference architecture for electric power systems. The abstract data models defined in IEC 61850 can be mapped to a number of protocols. Current mappings in the standard are to MMS ( Manufacturing Message Specification ),…
What is the IEC 61850 standard for GOOSE messages?
IEC 61850 standard defines a repetition mechanism for the GOOSE messages that is useful to check that the sender is alive and it is sending the required information. This is an advantage in comparison with the copper wiring where a broken cable may not be easily detected.
How is MMS protocol used in industrial automation?
The protocol used in this exchange use the MMS protocol (Manufacturing Message Specification) that is depicted in the standard ISO 9506. This protocol was developed for the industrial automation and it is one of the first protocols that identify data with hierarchies of names.
