This standa

25、rd 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 able to exchange information with other components and/or

26、 access publicly available data in a standard way. The 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 implementation of these messages using a particular component t

27、echnology is described in the 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 61970-403 Generic Data Access (GDA) defines services that are needed to access public en

28、tity objects for the power system domain that are defined in the IEC 61970-3xx series: Common Information Model (CIM). GDA permits a client to access data maintained by another component (either an application or database) or system without any knowledge of the logical schema used for internal stora

29、ge of the data. Knowledge of the existence of the common model is sufficient. This request and reply oriented service is intended for synchronous, non-real time access of complex data structures as opposed to high-speed data access of SCADA data, for example, which is provided by IEC 61970-404, High

30、 Speed Data Access. An example where the GDA would be used is for bulk data access of a persistent store to initialise an analysis application with the current state of a power system network, and then storage of the results with notification.

31、ANGE CHINA STANDARDS, 06/01/2009 01:52, Uncontrolled Copy, (c) BSIENERGY MANAGEMENT SYSTEM APPLICATION PROGRAM INTERFACE (EMS-API) Part 403: Generic data access 1 Scope This International Standard provides a generic request/reply-oriented data access mechanism for applications from independent suppl

32、iers to access CIM data in combination with IEC 61970-402: Common Services. An application is expected to use the Generic Data Access (GDA) service as part of an initialisation process or an occasional information synchronization step. GDA is generic in that it can be used by an application to acces

33、s any CIM data. GDA is also generic in that it also provides a back end storage mechanism independent query capability that can be used to facilitate the creation of CIM data warehouses. This specification provides a simple, concise service that meets the functionality requirements of current and fu

34、ture applications while: avoiding unnecessary complexity; not requiring any specific database technology for implementation. This service is designed to support interaction where the application or system requesting information is developed, supplied, maintained, or operated by a separate agency fro

35、m the application supplying the data. Furthermore, the update portion of this service assumes that it is undesirable for one system to directly write into another1). To support these objectives, the GDA capabilities are divided into three categories: a) read access; b) update access; c) change notif

36、ication events. It should be noted that the update portion of this service does not support unconditional access to critical real-time data. Rather, the update portion allows a requesting application to ask for data to be changed in a service provider, but the service provider is under no obligation

37、 to carry out that change at any particular time. Furthermore, a positive response from the update service does not indicate that the update has occurred, but only that the service provider has successfully received the request and that the request is syntactically and semantically correct. GDA coul

38、d be classified as an Enterprise Information Integration (EII) technology adapter specialized to the power industry via the assumed use of the CIM. There are a number of EII products currently available on the market, but there is no accepted cross-platform standard for writing connectors for these

39、products and overall these products do not take full advantage of a common semantic model such as the CIM. In recommending GDA, WG 13 is recommending a standard EII connector model in the form of a simpler, less expensive, and more specialized interface. _ 1) For more information on how 61970 exclud

41、e utility control center technical domain, generic data access encompasses a general set of concepts that can be applied to many types of systems. Examples of these systems include: Energy and distribution management systems Work and asset management systems Geographic information systems Outage man

42、agement systems Other types of technically oriented 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 GDA requirements to the extent that they are common to

43、 different types of systems while effectively addressing utility operation application specific needs. 2 Normative references The following referenced documents are indispensable for the application of this document.

47、 IEC 61970 specifies Component Interface Specifications (CIS) for Energy Management Systems Application Program Interfaces (EMS-API). It specifies the interfaces that a component (or application) shall implement to be able to exchange information with other components (or applications) and/or to acc
