19、EC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in additi
20、on to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee intereste
21、d in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with c
22、onditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC
23、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 reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for th
24、e 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 apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any
25、 IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users shou
26、ld ensure that they have the latest edition of this publication. 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 dama
27、ge of any nature whatsoever, whether direct or indirect, 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
28、the referenced publications is indispensable for the correct 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 right
29、s. International Standard IEC 61970-402 has been prepared by IEC technical committee 57: Power systems management and associated information exchange. The text of this standard is based on the following documents: FDIS Report on voting 57/928/FDIS 57/947/RVD Full information on the voting for the ap
30、proval of this standard can be found in the report on voting indicated in the above table. A list of all parts of the IEC 61970 series, under the general title Energy management system application program interface (EMS-API), can be found on the IEC website. 61970-402 IEC:2008(E) 5 This publication
31、has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At
32、this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 6 61970-402 IEC:2008(E) INTRODUCTION This standard is one of the IEC 61970 series parts that define an application program inte
33、rface (API) for utility operational systems. This standard is based upon the work of the Electric Power Research Institute (EPRI) Control Center API (CCAPI) research project (RP-3654-1). The IEC 61970-4xx series specifies a set of interfaces that a component (or application) should implement to be a
34、ble to exchange information with other components and/or access publicly available data in a standard way. The IEC 61970-4xx series component interfaces describe the specific event types and message contents that can be used by applications independent of any particular component technology. The imp
35、lementation of these messages using a particular component technology is described in the IEC 61970-5xx series of documents. Thus, IEC 61970-4xx documents describe a Platform Independent Model (PIM), while IEC 61970-5xx documents describe a Platform Specific Model (PSM). IEC 61970-402 contains API s
36、ervices that are considered to be foundational. As such, all the other parts in the IEC 61970-4xx series assume their existence. As a result, the services described in IEC 61970-402 are required for any component that complies with the IEC 61970-4xx series. The component interface specifications ref
37、er to entity objects for the power system domain that are defined in the IEC 61970-3xx series: Common Information Model (CIM). This standard contains normative and informative text. Clauses are marked as normative or informative. A subclause inherits its parent clauses label unless overridden by the
38、 lower level subclause label. 61970-402 IEC:2008(E) 7 ENERGY MANAGEMENT SYSTEM APPLICATION PROGRAM INTERFACE (EMS-API) Part 402: Common services 1 Scope This International Standard provides the base functionality considered necessary and common that is provided by neither the normative standards inc
39、orporated by reference nor the new APIs specified in the IEC 61970-403 to IEC 61970-449 1)generic interface standards. An application is expected to use the Common Services in conjunction with the generic interfaces. These application category independent interfaces include: IEC 61970-403: Generic D
40、ata Access (GDA) IEC 61970-404: High Speed Data Access (HSDA) IEC 61970-405: Generic Eventing and Subscription (GES) IEC 61970-407: Time Series Data Access (TSDA) To support these objectives, the Common Services are divided into three categories: a) Resource Identifiers A common way of identifying c
41、lasses, class attributes, and object instances. b) Resource Description A common way of encoding values associated with classes, class attributes, and object instances. c) Views A common way of presenting classes, class attributes, and object instances via hierarchies. IEC 61970-402 contains API ser
42、vices that are considered to be foundational. As such, all the other parts in the IEC 61970-4xx series assume their existence. As a result, the services described in IEC 61970-402 are required for any component that complies with the IEC 61970-4xx series of standards. Though the target of this IEC s
43、tandard includes the control center technical domain, common services encompass a general set of concepts that can be applied to many types of systems. Examples of these systems include: Distribution management systems Work or asset management systems Geographic information systems Outage management
44、 systems Other types of operational business systems. In recognition that the integration between applications in two or more of these systems is often necessary, the intent of this specification is to address general common service requirements to the extent that they are common to different types
45、of systems while effectively addressing the control center needs. _ 1)At this time, only parts 402 to 408 exist. Additional generic services beyond are not yet under consideration. 8 61970-402 IEC:2008(E) 2 Normative references The following referenced documents are indispensable for the application
