Introduction This introduction is not part of IEEE Std 762-2006, IEEE Standard Definitions for Use in Reporting Electric Generating Unit Reliability, Availability, and Productivity. Measures of generating unit performance have been defined,
10、 recorded, and utilized by the electric power industry for over 60 years. The increased focus on generating unit performance in a competitive marketplace has caused regulatory agencies and the industry to place a greater emphasis on performance measures. This standard was developed in 1987, based on
11、 efforts started in 1980, to provide terminology and indexes for use in existing data systems or in future systems. The focus of this revision is on performance measures to be used in a competitive marketplace. Some indexes are based on period hours. By use of such a common base, simple additive rel
12、ationships between various indexes result, and the use of period hours gives sets of indexes that sum to 100%. Other indexes are not based on period hours. This revision of the standard has included terms for units involved in nonbase load operations. The IEEE 762 Working Group defined sufficient da
13、ta categories (states, times, capacity levels) so that suitable indexes for all types of units can be calculated. It should be noted that even the use of all the indexes and terms cannot identify the underlying and sometimes compelling reasons for lost performance. The IEEE 762 Working Group perform
14、ed an in-depth review of the concept and practices for commercial availability. The working group unanimously agreed that commercial availability should be studied further, but it should not be a part of this standard. It would be best addressed in a new standard. Efforts for developing such a new s
15、tandard were judged to be outside the scope of the working groups charge and responsibility.

IEEE Standard Definitions for Use in Reporting Electric Generating Unit Reliability, Availability, and Productivity 1. Overview Although a generating unit generally includes all e
47、quipment from the fuel supply system up to the high-voltage terminals of the generator step-up transformer and the station service transformers, any event preventing the ability of the generating unit to produce electricity at its maximum capacity is covered in the scope of this standard. Sometimes,
48、 the generating unit cannot provide the power required to the customer because of problems not related to the power plant equipment. Some examples of these “external events” are transmission system failures, labor strikes, and catastrophic storms. NOTESee Annex D for a discussion on these external e
49、vents.1Reliability in this standard encompasses measures of the ability of generating units to perform their intended function. Availability measures are concerned with the fraction of time in which a unit is capable of providing service and accounts for outage frequency and duration. Productivity measures are concerned with the total power produced by a plant with respect to its potential power production. A plant could comprise a unit or a number of units. Therefore, productivity measures consider magnitude of event as well as frequency and du
