30、MMISSION _ ENERGY EFFICIENCY THROUGH AUTOMATION SYSTEMS FOREWORD 1) The International Electrotechnical 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-oper

31、ation 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 Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as

32、 “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. International, governmental and non- governmental organizations liaising with the IEC also participate in this pre

33、paration. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international con

34、sensus 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 international use and are accepted by IEC National Committees in that sense. While all reasonable efforts

35、 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) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

36、 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 be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Indepen

37、dent 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 certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No lia

38、bility 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 whatsoever, whether direct or indirect, or for costs (inc

39、luding 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 publications is indispensable for the correct application o

40、f 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 IEC technical committees is to prepare International S

41、tandards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC 62837, which is a technical report, has been prepared by I

42、EC technical committee 65: Industrial-process measurement, control and automation. The text of this technical report is based on the following documents: Enquiry draft Report on voting 65/513/DTR 65/517/RVC Full information on the voting for the approval of this technical report can be found in the

43、report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. TR 62837 IEC:2013(E) 7 The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site unde

44、r “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover pag

45、e of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 8 TR 62837 IEC:2013(E) INTRODUCTION Energy efficiency has received an ever growing attention wo

46、rldwide since it is considered a major lever to help secure a sustainable society in view of climate change, growing population and security of supply 1 1 . Additionally the sustainability and conservation of resources need to be considered. Automation is the enabler of measures, solutions and syste

47、ms for demand/response and energy efficiency. In the context of this TR we will only consider energy efficiency. IEC and ISO have both identified energy efficiency as one of their main areas of activity. The current focus of the Standard Development Organisations (SDO) is harmonised terminology, cal

48、culation methods, indicators, energy management systems and standards for assessment and ratings (e.g. for buildings and industrial plants). For this purpose IEC SMB Decision 128/20 “New initiatives for IEC” work endorsed the SMB Strategic Group 1 on Energy Efficiency and Renewable Energy. This stra

49、tegic group has since then developed 34 recommendations for future work in different domains. The three following recommendations cover the area of automation: Recommendation #7: IEC/TC 2, SC 22G and TC 65 together with ISO/TC 184 should develop guidelines for the design and operation of energy efficient systems in the field of industrial automation and industrial process control from a system point of view.
