IEEE 762-2006 pdf free.IEEE Standard Definitions for Use in Reporting Electric Generating Unit Reliability, Availability, and Productivity.”
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 (ONIC), 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.

3. Definitions
[his clause provides the conceptual detiniflons 01 the basic perlormance indexes while the equations to calculate the indexes are included in Clause 8 or Clause 10. The specific subclause in Clause 8 or Clause 10 is referenced for each defined term.
3.1 aaiIability factor (AF): The fraction of a given operating period in which a generating unit is available without any outages.
NOTE—See 8.6.
3.2 demand forced outage rate (FOR4j): 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 probability (DAUFOP): A measure of the probability that a generating unit will not be available when needed (derating included).
NOTE—See 8.17.3.
3.4 equivalent availability factor (EAF): The fraction of a given operating period in which a generating unit is available without any outages and equipment or seasonal deratings. NOTE—See 8.11.
3.5 equivalent availability factor excluding seasonal deratings (EAF5): The fraction of a given operating period in which a generating unit is available without any outages and equipment deratings. NOTE—Sec 8.11.1.IEEE 762 pdf download.
