摘　　要：提出了大型火电设备可用性评定新技术,内容包括可用性的区间估计、增长分析模型和验证试验方案。给出了可用系数AF、不可用系数UF、强迫停运率FOR、运行率SER、等效可用系数EAF和等效强迫停运率EFOR的点估计和区间估计的公式,用于鉴定大型火电设备的可用性水平。给出了AF、UF、FOR、SFR、EAF和EFOR的可用性增长模型,用于评定大型火电设备可用性改进的效果。给出了AF、UF、FOR、SER、EAF和EFOR的验证试验方案,用于考核大型火电设备的可用性水平是否达到合同要求的指标值。给出了大型火电设备可用性的区间估计、增长分析和现场验证试验的实例。该新技术为大型火电设备可用性的鉴定、评定和验收提供了科学的依据。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, service 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 verified 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 verified test for availability indexes of large capacity thermal power equipments are given. The new technology may provide a scientific basis for availability authentication, assessment and acceptance of large capacity thermal power equipments.
