中文摘要	运行可靠性概念和评估理论建立了基于实时运行条件的元件可靠性模型,综合考虑了机组的运行方式、负荷的实时变化、网络结构的变化等实时运行条件对运行可靠性的影响。文章在此基础上提出了元件实时可靠性模型的建模原则,并给出了线路的双曲函数模型,详细分析了线路实时可靠性模型参数的变化对模型本身及评估结果的影响,包括线路停运概率统计值、线路潮流越限阈值、线路额定容量等参数变化带来的影响,并进一步提出了实际工程中线路实时可靠性模型参数的选取方法。; By use of the concept of operational reliability and evaluation theory, a component’s reliability model based on real-time operating condition is built, in which the impacts of units’ operating mode, real-time fluctuation of power load and variation of power network structure on operational reliability are comprehensively considered. On this basis the modeling principle for component’s real-time reliability is proposed, the hyperbolic function model of transmission line is given, the impacts of the parameter variation of real-time reliability model of transmission line, such as probability statistics of transmission line outage, power flow off-limit threshold of transmission line, rated capacity of transmission line and so on, on evaluation results as well as on the model itself are analyzed in detail, furthermore, the method to choose the parameters of practical real-time reliability model of transmission line is put forward.; 国家重点基础研究发展计划项目(973项目)(2004CB217904)。~~
