What is IED in IEC 61850?
The intelligent electronic device (IED) is a basic element of the smart grid, delivering the sensing, measurement, protection, and control functionality required by the system.
What is IED configuration tool?
The IED configuration tool framework is used to develop OEM specific configuration tool and is specific for an IED/family of IEDs. The IED configuration tool framework helps OEMs customize to specific device parameters.
What is IEC 61850 and what are the aims of IEC 61850?
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.
How does an IEC 61850 work?
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.
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 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.
What is CID file in relay?
Configured IED Description (CID) file: It is a file used to have communication between an IED configuration tool to an IED. It can be considered as an SCD file stripped down to what the concerned IED need to know and contains a mandatory communication section of the addressed IED.
Is IEC 61850 secure?
Like other industrial protocols, IEC 61850 is not designed with security in mind, which could pose a serious risk for power companies if security is not addressed on timely manner.
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 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 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 IED file?
IED Capability Description (ICD) files are a specific type of Substation Configuration Language (SCL) file, containing a generic description of the whole capability range of a given device, including the functions and objects it can support. The ICD file is usually supplied by the developer/manufacturer.
