11、chnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical 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 t
12、his end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject de
13、alt with may participate in this preparatory work. International, 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 determine
14、d by agreement between the two organizations. 2) The formal 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
15、. 3) IEC Publications have the form of recommendations for 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
16、 are used or for any misinterpretation by any end user. 4) 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 an
17、d the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they
18、 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 injury, property damage or other damage of any nature wh
19、atsoever, 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 cited in this publication. Use of the referenced publ
20、ications 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 identifying any or all such patent rights. The main task of
21、 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 International Standard, despite repeated efforts, or th
22、e 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 publication to decide whether they can be transformed int
23、o International Standards. IEC 61850-2, which is a technical specification, has been prepared by IEC technical committee 57: Power system control and associated communications. 4 TS 61850-2 IEC:2003(E) The text of this technical specification is based on the following documents: Enquiry draft Report

30、ONS - Part 2: Glossary 1 Scope This part of the IEC 61850 series applies to Substation Automation Systems (SAS). It defines the communication between intelligent electronic devices (IEDs) in the substation and the related system requirements. This part of the IEC 61850 series contains the glossary o
31、f specific terminology and definitions used in the context of Substation Automation Systems within the various parts of the standard. 2 Terms and definitions The following terms and definitions apply to all parts of the IEC 61850 series 2 . 2.1 abstract communication service interface virtual interf

This may be a serial port, an Ethernet connection, or a client or server address dependent on the stack being used. Each access point of an IED to a communication bus is uniquely identified. Each server ha

36、a and of a specific type IEC 61850-8-1 2.6 bay a substation consists of closely connected sub parts with some common functionality. Examples are the switchgear between an incoming or outgoing line, and the busbar, the bus coupler with its circuit breaker and related isolators and earthing switches,
37、the transformer with its related switchgear between the two busbars representing the two voltage levels. The bay concept may be applied to 1 breaker and ring bus substation arrangements by grouping the primary circuit breakers and associated equipment into a virtual bay. These bays comprise a power
38、system subset to be protected, for example a transformer or a line end, and the control of its switchgear that has some common restrictions such as mutual interlocking or well- defined operation sequences. The identification of such subparts is important for maintenance purposes (what parts may be s
39、witched off at the same time with minimum impact on the rest of the substation) or for extension plans (what has to be added if a new line is to be linked in). These subparts are called bays and may be managed by devices with the generic name bay controller and have protection systems called bay pro
40、tection. The concept of a bay is not commonly used in North America. The bay level represents an additional control level below the overall station level IEC 61850-1 2.7 bay level functions functions that use mainly the data of one bay and act mainly on the primary equipment of that bay. Bay level f
