10、SION _ COMMUNICATION NETWORKS AND SYSTEMS FOR POWER UTILITY AUTOMATION Part 80-4: Translation from the COSEM object model (IEC 62056) to the IEC 61850 data model FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national el

11、ectrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Speci

12、fications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. Internat

13、ional, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The forma

14、l decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion 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

15、 international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to 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)

16、 In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently 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

17、 be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certifi

18、cation bodies. 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 its technical committees and IEC National Committees for any personal injur

19、y, 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 other IEC Publications. 8) Attention is drawn to the Normative references ci

20、ted 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 the subject of patent rights. IEC shall not be held responsible for identify

21、ing 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 when the required support cannot be obtained for the publication of an Inte

22、rnational 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. Technical specifications are subject to review within three years of public

23、ation to decide whether they can be transformed into International Standards. IEC TS 61850-80-4, which is a technical specification, has been prepared by IEC technical committee 57: Power systems management and associated information exchange.

PD IEC/TS 61850-80-4:2016IEC TS 61850-80-4:2016 IEC 2016 5 INTRODUCTION IEC 61850 defines communication networks and systems for power utility automation, and mor

29、e specifically the communication architecture for subsystems such as substation automation systems, feeder automation systems and SCADA for distributed energy resources. In essence, IEC 61850 is a description of the communication architecture for the overall power system management when the combined

30、 total of the above mentioned subsystems are considered. The devices in the electricity grid are becoming more intelligent with an increasing number of elements and increasing complexity of data to be processed in a distributed environment. Introduction of comprehensive data models simplifies the ha

31、ndling and management of the data drastically since the models can be re-used once standardized. By defining a number of standardized hierarchical names, it can drastically reduce errors in the field. The names in the standard can be directly used for the configuration of devices and the communicati

32、on between devices. This part of IEC 61850, which is a technical specification, defines the one-to-one relationship of IEC 62056 OBIS codes to IEC 61850 Logical Nodes. The purpose is to increase the availability of revenue meter information to other applications defined within the IEC 61850 framewor

33、k. This increased visibility will contribute to information available for smart grid applications. The other benefit of defining these relationships is in regards to the design of protocol converters. With a clear specification, test cases can be developed as well as end user understanding of the qu

34、antities is unambiguous. Finally, end user configuration is simplified by limiting the options for translation.

35、o the IEC 61850 data model 1 Scope Included within the IEC 61850 power utility automation architecture are its concepts, data models, communication protocols and the mapping data exchanges on the substation network. This extends beyond just IEDs to other IEC 61850 enabled devices like meters, system

36、 applications and remote access gateways. This part of IEC 61850, which is a technical specification, considers the requirements of power utility automation applications; i.e. the scope is limited by the use cases relevant for meter data exchange in HV/MV substations and MV/LV substations. Only use

37、cases that require the data exchange involving a revenue meter are considered. Applications not covered by the existing standards listed in Clause 2 are out of scope. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensabl

38、e for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

44、n System according to IEC 62056-6-1, uniquely identifying data objects within COSEM compliant metering equipment. COSEM Interface Class (IC) The Interface Class (IC) defines the common characteristics (by means of attributes and methods) of a set data objects. The interface class specifies the chara

45、cteristics of the objects encountered at the interface through which a system interacts with the objects. Implementation issues are not considered. An IC consists of several attributes and methods. The first attribute is always the “logical name”. The set of standardised Interface Classes are define

46、d in IEC 62056-6-2. COSEM object An Interface class is instantiated by assigning a specific OBIS code to the logical name of the IC. The result of the instantiation of an IC is a specific data object. The instantiation of an Interface Class may be part of the meter configuration or part of the produ

47、ction process. A meter operating in the field contains a set of objects. Data is exchanged by accessing these objects. Example: the IC “Register” defines the generic data structure for any metering register containing 3 attributes (logical name, measured value and the unit). By assigning the logical

48、 name “total electrical energy A +” to the IC “Register” we have formed a specific data object providing information on the totally energy consumption. The set of standardised OBIS codes are defined in IEC 62056-6-1. Class ID(CID) The Class ID identifies a specific class of the set of standardised I

49、nterface Classes. For example, Class_ID of 3 identifies the class type “Register”. Physical Device A physical device is a subsystem which has a physical connection to a communication medium and which can be addressed by a physical address. The behaviour of the physical device is modelled with a set of logical devices. A physical device must contain a “management logical device”. Logical Device A logical device is an abstract entity within a physical device. A log
