This standard is based upon the work of the Electric Power Research Institute (EPRI) Control C
35、enter 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 access publicly available data in a standard way. The 61970-4xx series component i
36、nterfaces 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 technology is described in the 61970-5xx series of documents. Thus, IEC 61970-4xx do
37、cuments 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 entity objects for the power system domain that are defined in the IEC 61970-3xx seri
38、es: 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 storage of the data. Knowledge of the existence of the common model is sufficient. This
39、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 Speed Data Access. An example where the GDA would be used is for bulk data access
40、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. DIN EN 61970-403:2009-01 EN 61970-403:2008 6 ENERGY MANAGEMENT SYSTEM APPLICATION PROGRAM INTERFACE (EMS-API) Part 403: Generic data access
41、 1 Scope This International Standard provides a generic request/reply-oriented data access mechanism for applications from independent suppliers 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 a
42、n initialisation process or an occasional information synchronization step. GDA is generic in that it can be used by an application to access 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 creati
43、on of CIM data warehouses. This specification provides a simple, concise service that meets the functionality requirements of current and future applications while: avoiding unnecessary complexity; not requiring any specific database technology for implementation. This service is designed to support
44、 interaction where the application or system requesting information is developed, supplied, maintained, or operated by a separate agency from the application supplying the data. Furthermore, the update portion of this service assumes that it is undesirable for one system to directly write into anoth
45、er1). To support these objectives, the GDA capabilities are divided into three categories: a) read access; b) update access; c) change notification 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
46、portion allows a requesting application to ask for data to be changed in a service provider, but the service provider is under no obligation 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 o
47、nly that the service provider has successfully received the request and that the request is syntactically and semantically correct. GDA could 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
48、number of EII products currently available on the market, but there is no accepted cross-platform standard for writing connectors for these 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
49、 EII connector model in the form of a simpler, less expensive, and more specialized interface. _ 1) For more information on how 61970 excludes direct control of one application by another, see IEC 61970-402 Annex C: The IEC 61970 services and mapping IEC 61968 verbs.
