IEEE 762-2006 pdf free download – IEEE Standard Definitions for Use in Reporting Electric Generating Unit Reliability, Availability, and Productivity
1.1 Scope This document standardizes terminology and indexes for reporting electric generating unit reliability, availability, and productivity performance measures while recognizing the power industry ‘s needs, including marketplace competition. This standard also includes equations for equivalent demand forced outage rate (EFORd), newly identified outage states, discussion of commercial availability, energy weighted equations for group performance indexes, definitions of outside management control (OMC), pooling methodologies, and time-based calculations for group performance indexes.
1.2 Purpose This standard is intended to aid the electric power industry in reporting and evaluating electric generating unit reliability, availability, and productivity. It was originally developed to overcome difficulties in the interpretation of electric generating unit performance data from various systems and to facilitate comparisons among different systems. The standard also makes possible the exchange of meaningful data among systems in North America and throughout the world.

This clause prov ides the conceptual definitions of the basic performance indexes while the equations to calculate the indexes are included in (bust K or Clause lit The speci tic suhclause in Clause X or Clause Itt is referenced for each defined term
3.1 asailahilln factor (AF): The fraction of a gisen ostrating period in which a generating unit is available without any outages.
NOTE—Sec 8.6.
3.2 densa.d forced outage rate (FORd: A measure of the probability that a generating unit will not be available due to forced outages when there is demand on the unit to generate.
NOTE—See 8.16.2.
3.3 derating adjusted utilization forced outage probabilin tDAt FOP): A measure of the probability that a generaung unit will not be available when needed tderating ineluded).
NOTE—Sec 8.173.
3.4 cqun’alcnt availability factor (FAF): The fraction of a given operating pcnod in which a generating unit is available without any outages and equipment or seasonal dczatings.
NOTE—See 8.11,
3.5 equisate.t availahilit factor ncludi.g seasonal deratings (IAk5): the fraction of a given operating period in which a generating unit ia available without any outages and equipment deratings.
NOTE—See 8.1 tI.
3.6 esluhatnht lOrced outage factor ([1(11): ‘[he fraction of a given operating period in which a generating unit is not available due to lotted outages and dcratings.
NOTE Sec S.2t
3.7 equIvalent forced outage rate (EFOR): A measure of the probability that a generating unit will not be available due to tiirced outages tsr forced ste-ratings.
NOTE— See 8.17.
3.8 equlsaletit demand forced outage rate (EFOIt): A measure of the probability that a generating unit will not he asailable due to foited outages or forced deratings when there is demand sin the unit to generate.
NOTE—Sec 8.1 7.2.
3.9 equisaleiit forced outage rate total—ge.eratlng or other functions (EFOR): A measute of the probability that a generating unit will not be available due to forced outages or forced dcratinga incltiding the exposure to nongenerating functions.
