7、C UTILITIES SYSTEM INTERFACES FOR DISTRIBUTION MANAGEMENT Part 2: Glossary FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote in
8、ternational co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (herea
9、fter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also parti
10、cipate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an
11、 international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all
12、reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to appl
13、y IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of c
14、onformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publ
15、ication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect,
16、 or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the cor
17、rect application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepa
18、re International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical de
19、velopment or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC 61968-
20、2, which is a technical specification, has been prepared by IEC technical committee 57: Power systems management and associated information exchange. DD IEC/TS 61968-2:2011 4 TS 61968-2 IEC:2011(E) The text of this technical specification is based on the following documents: TS Report on voting 57/1
21、054/DTS 57/1088/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives Part 2. This second edition cancels and replaces the firs
22、t edition published in 2003. This second edition constitutes a technical revision. It contains numerous new terms in support of IEC 61968-9, as well as revisions to terms found in the first edition. The reader will find citations to bibliographic references within square brackets below many of the t
23、erm definitions. Cross references between many related terms have also been added to this edition. These are located among the notes and begin with the words “See also.” A list of all the parts in the IEC 61968 series, published under the general title Application integration at electric utilities S
24、ystem interfaces for distribution management can be found on the IEC website. A bilingual version may be issued at a later date. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“
25、in the data related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. DD IEC/TS 61968-2:2011TS 61968-2 IEC:2011(E) 5 INTRODUCTION The IEC 61968 series is intended to facili
26、tate inter-application integration, as opposed to intra-application integration, of the various distributed software application systems supporting the management of utility electrical distribution networks. Intra-application integration is aimed at programs in the same application system, usually c
27、ommunicating with each other using middleware that is embedded in their underlying runtime environment, and tends to be optimized for close, real-time, synchronous connections and interactive request/reply or conversation communication models. IEC 61968, by contrast, is intended to support the inter
28、-application integration of a utility enterprise that needs to connect disparate applications that are already built or new (legacy or purchased applications), each supported by dissimilar runtime environments. Therefore, IEC 61968 is relevant to loosely coupled applications with more heterogeneity
29、in languages, operating systems, protocols and management tools. IEC 61968 is intended to support applications that need to exchange data on an event driven basis. IEC 61968 is intended to be implemented with middleware services that broker messages among applications, and will complement, but not r
30、eplace utility data warehouses, database gateways, and operational stores. The series of standards will be using a lot of definitions, terms and abbreviations from the area of distribution management as well as from the area of Information and Communication Technology. This glossary part defines the
31、 terms and abbreviations as they are used in the context of this series of standards. DD IEC/TS 61968-2:2011 6 TS 61968-2 IEC:2011(E) APPLICATION INTEGRATION AT ELECTRIC UTILITIES SYSTEM INTERFACES FOR DISTRIBUTION MANAGEMENT Part 2: Glossary 1 Scope This part of IEC 61968 identifies and explains te
32、rms and abbreviations used in the remaining parts of IEC 61968. This glossary, accompanying the IEC 61968 series, is the second part in the series that, taken as a whole, defines interfaces for the major elements of an interface architecture for distribution management systems (DMS). As used in IEC
33、61968, a DMS consists of various distributed application components for the utility to manage electrical distribution networks. These capabilities include monitoring and control of equipment for power delivery, management processes to ensure system reliability, voltage management, demand-side manage
34、ment, outage management, work management, automated mapping and facilities management. 2 Terms and definitions For the purposes of the IEC 61968 series, the following terms and definitions apply. 2.1 abstract component smallest logical block of software considered in the IEC 61968 interface referenc
35、e model NOTE Abstract components have interfaces that will be defined in parts 3 to 10 of the IEC 61968 series. It is expected that different vendors will supply physical application components that support the interfaces for one or more abstract components. 2.2 absolute data data which is based on
36、a fixed sample at a prescribed moment in time NOTE 1 The data may have been scaled and may consist of a signed value (as opposed to unsigned). Aclara 2008 NOTE 2 See also: “incremental data“. 2.3 account number unique number issued by a customer information system to identify a specific customer acc
37、ount within a given utility Aclara 2008 2.4 accuracy (of a measurement) quality of freedom from mistake or error, that is, of conformity to truth or to a rule NOTE 1 Accuracy is distinguished from precision as in the following example: A six-place table is more precise than a four-place table. Howev
38、er, if there are errors in the six-place table, it may be more or less accurate than the four-place table. DD IEC/TS 61968-2:2011TS 61968-2 IEC:2011(E) 7 NOTE 2 The accuracy of an indicated or recorded value is expressed by the ratio of the error of the indicated value to the true value. It is usual
39、ly expressed in percent. Since the true value cannot be determined exactly, the measured or calculated value of highest available accuracy is taken to be the true value or reference value. Comparison of results obtained by different measurement procedures is often useful in establishing the true val
