25、 standard is one of the IEC 61970 series parts that define an application program interface (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 sp
26、ecifies a set of interfaces that a component (or application) should implement to be able 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 c
27、an be used by applications independent of any particular component technology. The implementation 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 6197
28、0-5xx documents describe a Platform Specific Model (PSM). IEC 61970-402 contains API services 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 t
29、hat complies with the IEC 61970-4xx series. The component interface specifications refer 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
30、or informative. A subclause inherits its parent clauses label unless overridden by the lower level subclause label.

31、I) 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 incorporated by reference nor the new APIs specified in the IEC 61970-403 to IEC 61970-449 1)generic interface standard
32、s. 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 Data Access (GDA) IEC 61970-404: High Speed Data Access (HSDA) IEC 61970-405: Generic Eventing and Subscription (GES)
33、 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 classes, class attributes, and object instances. b) Resource Description A common way of encoding values associated w
34、ith 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 services that are considered to be foundational. As such, all the other parts in the IEC 61970-4xx series assume their
35、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 standard includes the control center technical domain, common services encompass a general set of concepts that can b
36、e applied to many types of systems. Examples of these systems include: Distribution management systems Work or asset management systems Geographic information systems Outage management systems Other types of operational business systems. In recognition that the integration between applications in tw
37、o 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 of systems while effectively addressing the control center needs. _ 1)At this time, only parts 402 to 408 exist. Add
38、itional generic services beyond are not yet under consideration.

NOTE Refer to International Electrotechnical Vocabulary, IEC 60050, for general glossary definitions. 4 Background This International Standard specifies Component Interface Specifications (CIS) for Energy Management Systems Application Program Interfaces (EMS-API). It
44、 specifies the interfaces that a component (or application) shall implement to be able to exchange information with other components (or applications) and/or to access publicly available data in a standard way (see IEC 61970-1 for an overview of these standards). The goal of the creation of this doc
45、ument is to improve the interoperability of control center applications and systems. This specification provides a mechanism for applications from independent suppliers to access IEC 61970 Common Information Model (CIM) data using a common Application Program Interface (API) for the purpose of suppl
46、ementary processing, storage, or display. IEC 61970-401, CIS Framework, provides an overview of the CIS documents in the IEC 61970-4xx series. It explains the separation of these specifications into two major groups. One group of standards, IEC 61970-402 to IEC 61970-449, defines a set of generic ap
47、plication independent services that a component shall use for exchanging information with another component or for accessing public data. However, as the generic interfaces do not specify what specific data is exchanged, interoperability between products using IEC 61970-402 to IEC 61970-449 is not g
48、uaranteed. The other group, IEC 61970-450 to IEC 61970-499, defines the information content conveyed using the generic services that a particular component or system exchanges with other components. While IEC 61970-402 to IEC 61970-449 specify BS EN 61970-402:2008 7 Licensed Copy: Wang Bin, ISO/EXCH
