NEW TECHNOLOGY FOR AVAILABILITY ASSESSMENT OF LARGE CAPACITY THERMAL POWER EQUIPMENTS

Abstract

Abstract: A new technology for availability assessment of large capacity thermal power equipments is presented. The technology includes availability interval estimation, availability growth analysis models and availability verified test plans. Some point estimation and interval estimation formulas for availability factor AF, unavailability factor UF, forced outage rate FOR, serv-ice rate SER, equivalent availability factor EAF and equivalent forced outage rate EFOR are given in use for authenticating availability level of large capacity thermal power equipments. Some availability growth models for AF, UF, FOR, SER, EAF and EFOR are given, for use with assessing availability improvement results of large capacity thermal power equipments. Some veri-fied test plans for AF, UF, FOR, SER, EAF and EFOR are given, for the use of checking whether or not availability level of large capacity thermal power equipments corresponds to availability index values in purchase contract. Some application examples for interval estimation, growth analysis and power station veri-fied test for availability indexes of large capacity thermal power equipments are given. The new technology may provide a sci-entific basis for availability authentication, assessment and acceptance of large capacity thermal power equipments.
