IEC 61968
IEC 61968 is a series of standards under development that will define standards for information exchanges between electrical distribution systems. These standards are being developed by Working Group 14 of Technical Committee 57 of the IEC (IEC TC 57 WG14). IEC 61968 is intended to support the inter-application integration of a utility enterprise that needs to collect data from different applications that are legacy or new and each has different interfaces and run-time environments. IEC 61968 defines interfaces for all the major elements of an interface architecture for Distribution Management Systems (DMS) and is intended to be implemented with middleware services that broker messages among applications.

Electricity Distribution
Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between and with the use of transformers. ''Primary'' distribution lines carry this medium voltage power to distribution transformers located near the customer's premises. Distribution transformers again lower the voltage to the utilization voltage used by lighting, industrial equipment and household appliances. Often several customers are supplied from one transformer through ''secondary'' distribution lines. Commercial and residential customers are connected to the secondary distribution lines through service drops. Customers demanding a much larger amount of power may be connected directly to the primary distribution level or the subtransmission level. The transition from transmission to distribut ...

Working Group
A working group, or working party, is a group of experts working together to achieve specified goals. The groups are domain-specific and focus on discussion or activity around a specific subject area. The term can sometimes refer to an interdisciplinary collaboration of researchers working on new activities that would be difficult to sustain under traditional funding mechanisms (e.g., federal agencies). The lifespan of a working group can last anywhere between a few months and several years. Such groups have the tendency to develop a ''quasi-permanent existence'' when the assigned task is accomplished; hence the need to disband (or phase out) the working group when it has achieved its goal(s). A working group's performance is made up of the individual results of all its individual members. A team's performance is made up of both individual results and collective results. In large organisations, working groups are prevalent, and the focus is always on individual goals, performan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Electrotechnical Commission
The International Electrotechnical Commission (IEC; in French: ''Commission électrotechnique internationale'') is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies – collectively known as "electrotechnology". IEC standards cover a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fibre optics, batteries, solar energy, nanotechnology and marine energy as well as many others. The IEC also manages four global conformity assessment systems that certify whether equipment, system or components conform to its international standards. All electrotechnologies are covered by IEC Standards, including energy production and distribution, electronics, magnetics and electromagnetics, electroacoustics, multimedia, telecommunication and medical technology, as well as associated general disciplines such as t ...

MultiSpeak
MultiSpeak is a specification that defines standardized interfaces among software applications commonly used by electric utilities, defining details of data that must be exchanged between software applications to support common utility processes. It is funded by the National Rural Electric Cooperative Association (NRECA). The National Institute of Standards and Technology (NIST) has developed a Smart Grid Conceptual Reference Model as part of its Smart Grid Standards Framework and Roadmap, and has identified 42 standards to support this vision. NIST chose MultiSpeak as a key standard in the Operations area of the NIST Conceptual Model.National Institute of Standards and Technology, NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 1.0, NIST Special Publication 1108, January, 2010. The MultiSpeak specification is the most widely applied integration standard in North American distribution utilities. It is currently used in the daily operations of more than ...

Common Information Model (electricity)
The Common Information Model (CIM) is an electric power transmission and distribution standard developed by the electric power industry. It aims to allow application software to exchange information about an electrical network. It has been officially adopted by the International Electrotechnical Commission (IEC). The CIM is currently maintained as a UML model. It defines a common vocabulary and basic ontology. CIM models the network itself using the 'wires model'. It describes the basic components used to transport electricity. Measurements of power are modeled by another class. These measurements support the management of power flow at the transmission level, and by extension, the modeling of power through a revenue meter on the distribution network. The CIM can be used to derive 'design artifacts' (e.g. XML or RDF Schemas) as needed for the integration of related application software. CIM is also used to derive messages for the wholesale energy market with the framework for ene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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), GOOSE (Generic Object Oriented System Event) ee section 3, Terms and definitions, term 3.65 on page 14 SV (Sampled Values) or SMV (Sampled Measure Values), and soon to Web Services. In the previous version of the standard, GOOSE stood for "Generic Object Oriented Substation Event", but this old definition is still very common in IEC 61850 documentation. These protocols can run over TCP/IP networks or substation LANs using high speed switched Ethernet to obtain the necessary response times below four milliseconds for protective relaying. ...
