The IEEE develops its standardsthrough a consensus development process, approved by the American National Standards Institute, which bringstogether volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are notnecessarily members

While the IEEE administers the process andestablishes rules to promote fairness in the consensus development process, the IEEE does not independentlyevaluate, test, or verify the accuracy of any of the information contained in its standards.Use of an

Every IEEE Standard issubjected to review at least every five years for revision or reaffirmation. When
11、 a document is more than fiveyears old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value,do not wholly reflect the present state of the art.

When the need for
14、interpretations is brought to the attention of IEEE, the Institute willinitiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of concernedinterests, it is important to ensure that any interpretation has also received the concurrence of a balance ofinterests. For
15、 this reason, IEEE and the members of its societies and Standards Coordinating Committees are notable to provide an instant response to interpretation requests except in those cases where the matter has previouslyreceived formal consideration.

All rights reserved.IntroductionThis guide is primarily tutorial in nature as it is intended to provide guidance in the design of electric powerservice systems for electric power generation plants. The guidance and direction given in this guide is, forthe most part, general in nature and
21、is applicable to all types and sizes of electric power generating plants.This guide does not provide unique and specific design direction and guidance for special systems in thevarious types of electric power generating plants, but rather provides the basic framework upon which anyrequired unique an
22、d specific designs can be built. An electric power service system consists of a mainauxiliary power distribution network, which may supply many subsystems such as electric trace heatingsystems, dc systems, Class 1E power systems, etc. It is recommended that the reader consult industrystandards that
23、address these specific subsystems in more detail as appropriate during the design process.This design guide was prepared by the Working Group on Auxiliary Systems, which is part of the StationDesign Subcommittee of the Energy Development and Power Generation Committee of the IEEE PowerEngineering So
24、ciety.This revision includes primarily editorial changes needed to maintain consistency with phraseology andterminology changes that have been made in other referenced standards and documents and to correcttypographical errors in the 1991 edition of this guide. It also includes only relatively minor
25、 technicalchanges. Notice to usersErrataErrata, if any, for this and all other standards can be accessed at the following URL: http:/standards.ieee.org/reading/ieee/updates/errata/index.html. Users are encouraged to check this URL forerrata periodically.InterpretationsCurrent interpretations can be

By publication of this standard, no position is taken with respect to t
27、he existence orvalidity of any patent rights in connection therewith.
