20、that defines Application Program Interfaces (APIs) for an Energy Management System (EMS). The IEC 61970-4XX and IEC 61970-5XX series documents comprise Component Interface Specifications (CISs). The IEC 61970-4XX series CIS are specified as Platform Independent Models (PIMs), which means they are in
21、dependent of the underlying technology used to implement them. PIM specifications are also referred to as Level 1 specifications. The IEC 61970-5XX series CIS, on the other hand, are specified as Platform Specific Models (PSMs). PSM specifications are also referred to as Level 2 specifications. IEC
22、61970-4XX CISs specify the functional requirements for interfaces that a component (or application) should implement to exchange information with other components (or applications) and/or to access publicly available data in a standard way. The component interfaces describe the specific event types
23、and message contents that can be used by applications for this purpose. IEC 61970-404 specifies an interface for the efficient transfer of data in a distributed environment. Small amounts of data are transferred with short delay but also large amounts of data are transferred in short time but with p
24、ossibly longer delay. This is a typical requirement for a SCADA system that acts as a real time data provider to other sub-systems. Other systems than SCADA may also benefit from the characteristics of HSDA. When short delay times as well as bulk data transfer is required, HSDA is a good fit. These
25、component interface specifications refer to entity objects for the power system domain that is defined in the IEC 61970-3XX series, including IEC 61970-301. 4 EN 61970-404:2007Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 02/01/2008 07:43, Uncontrolled Copy, (c) BSIENERGY MANAGEMENT SYSTEM
26、APPLICATION PROGRAM INTERFACE (EMS-API) Part 404: High Speed Data Access (HSDA) 1 Scope The IEC 61970-404 High Speed Data Access (HSDA) specification specifies a generalized interface for efficient exchange of data. The specification takes into account the latencies caused by a Local Area Network (L
27、AN) providing efficient data exchange also over Local Area Networks. IEC 61970-404 is derived from the Object Management Group (OMG) Data Acquisition from Industrial Systems section Data Access (DAIS DA) specification. OMG DAIS DA relies on the OMG Data Access Facility (DAF) and OPC Data Access (DA)
28、 specifications. OMG DAIS DA is a Platform Specific Model (PSM) with CORBA as the platform and OPC DA is a PSM with Microsoft COM as the platform. IEC 61970-404 describes the functionality of these PSMs in a technology independent way (i.e., as a Platform Independent Model (PIM). Hence it explains t
29、he functionality to a level that can be used to create additional PSMs or act as an introduction to existing PSMs, i.e. DAIS DA and OPC DA. Implementers wanting an introduction to OMG DAIS DA and OPC DA shall read these documents. The HSDA interface is intended to interoperate with other IEC 61970 b
30、ased interfaces. Hence, it is possible to use information retrieved from an other interface to access the same information using this interface, for example: object identifiers, attribute names or identifiers, class names or identifiers. Subclause 4.6 provides a generic mapping for the CIM classes a
31、nd attributes. The way data is organized in a server implementing the HSDA interface can be seen by using the browse interfaces for data and meta data. It is also possible to use the data access interface directly without using the browse interfaces if the client has an a priori knowledge of object,
32、 class and attribute identifiers. Object identifiers may be retrieved using data from other interfaces, for example a CIMXML file or the IEC 61970-403 interface. Information on what classes and attributes are available will be described in IEC 61970-45X documents, for example SCADA data, State Estim
33、ator results etc. IEC 61970-1 provides the EMS-API reference model upon which this standard is based. In that reference model, the terminology used in This part of IEC 61970 is introduced and the role of the CIS is explained. IEC 61970-401 provides an overview and framework for the CIS (IEC 61970-4X
34、X) standards. The mapping of IEC 61970-404 to implementation specific technologies or PSMs is further described in a separate series of documents, i.e. the future IEC 61970-5XX. For actual implementations, the future IEC 61970-5XX, OMG DAIS DA, OMG DAF or OPC DA are used. 5 EN 61970-404:2007Licensed

41、tribute name with a period in between, for example, the attribute “id” in the class “Node” will then be named “Node.id”. For attributes in sub structures multiple attribute names may be used, for example “Item.id.node_id” where the “node_id” is a part in the structure “Item.id”. 4 CIS Specification
42、4.1 Background (informative) For historical reasons, control systems for different industrial processes have evolved along different lines. Control systems for power systems have evolved on a UNIX base and control systems for most other industrial processes have evolved on a Windows base. For Window
43、s based control systems, OPC has become the dominating standard. For UNIX based systems, the DAIS API defined in Common Object Request Broker Architecture (CORBA) Interface Definition Language (IDL) has been developed. DAIS is based on OPC to benefit from the success of OPC and enable easy bridging
44、to OPC. With this intent Object Management Group (OMG) started in 1997 to develop a CORBA based interface with the same functionality as 6 EN 61970-404:2007Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 02/01/2008 07:43, Uncontrolled Copy, (c) BSIOPC. HSDA has the functionality from OMG DAIS
45、 DA and OPC DA described in a technology neutral way, hence HSDA is intended to be a Platform Independent Model (PIM). 4.2 SCADA use case (informative) A major component in a utility operational system is a SCADA system that acts as a real time data provider to other components or clients. Such a sy
46、stem typically has the following components: Process instrumentation making sensor data and actuation capabilities available. Remote Terminal Units (RTUs), process control or substation control systems reading sensor data and controlling actuators. Process communication units connecting to RTUs or s
47、ubstation control systems. Remote communication is typically solved by specialized RTU or field bus protocols (e.g. IEC 60870-5). The IEC 61850 series is a new standard for communication with and within substations. The interfaces defined in this part of IEC 61970 can be used as a standard API to en
48、capsulate such communication solutions at the client side. SCADA subsystem making processed sensor data and control capabilities available to operators, applications or other systems. An Energy Management System (EMS) using the SCADA subsystem for extended processing and control. Graphical User Inte
49、rfaces visualizing process data. SCADA and EMS systems can be regarded as having a server part where data processing is performed and a Graphical User Interface (GUI) part where visualization and command dialogues are made. The SCADA and EMS may have common or different GUIs. The architecture is shown in Figure 1 below.
