31、ot part of IEEE Std 1366-2012, IEEE Guide for Electric Power Distribution Reliability Indices. This guide was originally developed in 1998 to create indices specifically designed for distribution systems. Other groups have created indices for transmission and industrial systems, but none were availa
32、ble for distribution. This group will continue working in this area by refining the information contained in this guide. This guide was updated in the 2003 revision to clarify existing definitions and to introduce a statistically based definition for classification of Major Event Days. The working g
33、roup created a methodology, 2.5 Beta Method, for determination of Major Event Days. Once days are classified as normal or Major Event Days, appropriate analysis and reporting can be conducted. This 2012 revision of the guide clarified several of the definitions and introduced two new indices. The ne
34、w indices are CELID-sand CELID-t, customers experiencing long interruption durations (both single and total). A section was also added to explain the investigation of catastrophic days.

Overview 1.1 Introduction This full-use guide has been updated to clarify existing definitions, introduce two additional reli
41、ability indices, and add a discussion of Major Event Days and catastrophic days (see 5.3). 1.2 Scope This guide identifies distribution reliability indices and factors that affect their calculation. It includes indices, which are useful today, as well as ones that may be useful in the future. The in
42、dices are intended to apply to distribution systems, substations, circuits, and defined regions. 1.3 Purpose The purpose of this guide is twofold. First, it is to present a set of terms and definitions which can be used to foster uniformity in the development of distribution service reliability indi
43、ces, to identify factors which affect the indices, and to aid in consistent reporting practices among utilities. Secondly, it is to provide guidance for new personnel in the reliability area and to provide tools for internal as well as external comparisons. In the past, other groups have defined rel
44、iability indices for transmission, generation, and distribution but some of the definitions already in use are not specific enough to be wholly adopted for distribution. Users of this guide should recognize that not all utilities would have the data available to calculate all the indices. 2. Referen
45、ces The following standards shall be used, when applicable, in preparing manuscripts. When the following standard is superseded by an approved revision, the revision shall apply.

46、s For the purposes of this document, the following terms and definitions apply. The IEEE Standards Dictionary: Glossary of Terms and Definitions1should be consulted for terms not defined in this clause. Definitions are given here to aid the user in understanding the factors that affect index calcula
47、tion. Many of these definitions were taken directly from The Authoritative Dictionary of IEEE Standards Terms, 7th Edition B93. If there is a conflict between the definitions in this document and the dictionary, the definitions in this document take precedence. Others are given because they have a n
48、ew interpretation within this document or have not been previously defined. connected load: Connected transformer kVA, peak load, or metered demand (to be clearly specified when reporting) on the circuit or portion of circuit that is interrupted. When reporting, the report should state whether it is
49、 based on an annual peak or on a reporting period peak. customer: A metered electrical service point for which an active bill account is established at a specific location (e.g., premise). customer count: The number of customers either served or interrupted, depending on usage. distribution system: That portion of an electric system that delivers electric energy from transformation points on the transmission system to the customer. 1IEEE Sta nda rds Dictiona ry: Glossa ry of Terms a nd Definitions is available at http:/shop.ieee.org. 3The numbers in brac
