11、PROGRAM INTERFACE (EMS-API) 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 international co-operation on al
12、l 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 (hereafter referred to as “IEC Publi
13、cation(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 participate in this preparation. I
14、EC 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 international consensus of o
15、pinion 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 reasonable efforts are made t
16、o 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 apply IEC Publications transparen
17、tly 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 provides no marking procedure to indicate its approval and cannot be rend
18、ered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should 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 i
19、ts technical committees and IEC National Committees for any personal injury, property damage or other damage 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 ot
20、her IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of 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 th
21、e 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 prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification w
22、hen the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. T
23、echnical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards.

TS 61970-2 IEC:2004(E) 5 INTRODUCTION This Technical specification is part of the IEC 61970 series, which defines an Application Program
31、 Interface (API) for an Energy Management System (EMS). This standard is based upon the work of the EPRI Control Center API (CCAPI) research project (RP-3654-1). The principle objectives of the EPRI CCAPI project are to: reduce the cost and time needed to add new applications to an EMS; protect the
32、investment in existing applications that are working effectively in an EMS. The principal task of the CCAPI project is to develop a set of guidelines, or specifications, to enable the creation of “plug-in” applications 3in the control center environment. This part of the IEC 61970 series provides a
33、glossary of terms and abbreviations that are specific to the IEC 61970 series or may require interpretation as to how they were used in it. _ 3A plug-in application is defined to be a piece of software that may be installed on a system with minimal effort and no modification of source code; i. e., t
34、he way software packages are installed on a desktop computer. The CCAPI Project goal is to at least approach that ideal by reducing the often significant efforts currently required to install third-party applications in an EMS. 6 TS 61970-2 IEC:2004(E) ENERGY MANAGEMENT SYSTEM APPLICATION PROGRAM IN
35、TERFACE (EMS-API) Part 2: Glossary 1 Scope This Technical specification provides a glossary for the volume of work produced as part of the IEC 61970 series of documents. Terms and abbreviations that are either specific to the series, or that require explanation because of the way that they are used
36、in it, are supplied. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 6
37、1970-1, Energy Management System Application Program Interface (EMS-API) Part 1: Guidelines and general requirements 3 Terms and definitions For the purposes of this Technical specification, the terms and definitions given below apply. 3.1 aggregation special case of association 3.2 application piec
38、e of software that comprises one or more components that perform some business function in a given domain. The important aspect is the functionality performed and not the packaging of the software. An example would be a word processor. It has a fairly well understood functionality but the components
39、 that are actually installed can look very different depending on the vendor. 3.3 application context collection of applications working together as an organizational unit to accomplish some high- level objective 3.4 Application Program Interface API set of public functions provided by an executable
40、 application component for use by other executable application components 3.5 association connection between classes that can be assigned a role TS 61970-2 IEC:2004(E) 7 3.6 cardinality from multiplicity from the class that is being described, 0 is an optional association and n means that an unspeci
41、fied number of associations are allowed 3.7 cardinality to multiplicity and cardinality of the class on the other side of the association 3.8 Common Information Model CIM abstract model that represents all of the major objects in an electric utility enterprise that are typically contained in an Ener
42、gy Management System (EMS) information model. By providing a standard way of representing power system resources as object classes and attributes along with their relationships, the CIM facilitates the integration of EMS applications developed independently by different vendors, between entire EMSs
43、developed independently or between an EMS and other systems concerned with different aspects of power operations, such as generation or distribution management. 3.9 CIM context run-time environment within which all application instances operate to achieve a common objective 3.10 class description of
44、 an object found in the real world that needs to be represented as part of the overall power system model or a set of resources to which a given set of properties apply 3.11 communication profiles particular protocols and protocol services that are to be used for information exchange between separat
45、e server platforms in a component execution system 3.12 component reusable software building block: a pre-built piece of encapsulated application code that can be combined with other components and with handwritten code to rapidly produce a custom application. In order to qualify as a component, the
46、 application code must provide a standard interface that enables other parts of the application to invoke its functions and to access and manipulate the data within the component. For compiled languages, a component is usually a file of executable code (*.exe or *.dll) or resource files containing d
47、ata used by this or other applications. The component model defines the structure of the interface. 3.13 component adapter piece of software that sits between the application (or component) and the component container and integration infrastructure and which provides the fundamental component suppor
48、t services 3.14 component container components execute within a container. The container provides a context for one or more components and provides management and control services for the components. It also provides an operating system process or thread in which to execute the component. 8 TS 61970
49、-2 IEC:2004(E) 3.15 component execution system term encompassing the entire reference model from the container layer down including the component container, middleware services and communication profiles. It includes other normal platform supplied services as well, including the operating system, persistent storage, etc. NOTE Also known as container systems. 3.16 compon
