6、d the Standards Coordinating Committees of the IEEE Standards Board. Members of the committees serve volun- tarily and without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the subject within the I
7、nstitute as well as those activities outside of IEEE which have expressed an interest in participating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, m
8、arket, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. E
9、very IEEE Standard is subjected to review at least once every five years for revision or reaffirmation. When a document is more than five years 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 t
10、he art. Users are cautioned to check to deter- mine that they have the latest edition of any IEEE Standard. Comments for revision of IEEE Standards are welcome from any inter- ested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a
11、 proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will
12、 initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technical commit- tees
13、are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 345 East 47th Street New York, NY

15、word is not a part of BEE Std 859-1987, IEEE Standard Terms for Reporting and Analyzing Outage Occur- Data on outage occurrences of transmission facilities have been collected for many years. Initially, reporting was generally limited to reporting frequency of outage occurrence on transmission lines
16、. Total outage frequency was classified into several general cause categories, but there were no formal definitions for the events and statistics reported beyond those contained in the data forms and instructions. Early efforts did not generally collect data on outage duration, except to class outag
17、es as temporary or permanent according to type of restoration used. In the 1960s, methods were first proposed for calculating reliability of transmission and distribution “systems” (networks) in terms of the reliability of their individual “components? This led to the need for more formal definition
18、s of terms to foster uniformity and standardization of language among engineers engaged in reporting, analyzing, and predicting outages of transmission and distribution facilities and interruptions to customers. This resulted in development of IEEE Std 346-1973, IEEE Standard Defini- tions in Power
19、Operations Terminology Including Terms for Reporting and Analyzing Outages of Electri- cal Transmission and Distribution Facilities and Interruptions to Customer Service. More recent developments have shown the need to include definitions for a broader scope of outage events. For example, two genera
20、l categories of facilities (reportable entities) must be recognized to support presently available models. In one type of model, a transmission system is partitioned function- ally into “units” which represent the capability to transfer power between specified points. In the second type of model, a
21、system is partitioned physically into “components? Another recent development is the increasing recognition of the importance of “related outage occur- rences” in which outage occurrences of two or more facilities are related in some way due to the physical construction of equipment (such as common
22、structure), the electrical interconnection of equipment (common bus, for example), or exposure to a common environment (storms). Achieving clear and unambiguous definitions for related outage occurrences is important for reporting outage occurrences at the transmission unit level. At the component l
23、evel, an important consideration is the recognition of several modes of failure, particularly for switching, protection, and automatic reclosing equipment. No attempt is made here to standardize procedures for the collection of outage data. What is at- tempted is to speclfy certain common terms and
24、indices to provide a basis of information exchange. The task force has attempted to keep the list of terms and indices as brief as possible. The indices defined here are intended to serve as estimates for parameters of models which are used in transmission system reliability evaluation. The indices
