摘要
可用性作为核电厂安全级DCS可靠性分析指标中的一个基本参数,在对核电厂安全级DCS进行系统性能评估和系统可靠性评估时起着重要的参考作用。本文主要采用马尔可夫过程法,对2oo3架构的核电厂安全级DCS停堆保护系统进行马尔可夫建模,分析和计算得出2oo3架构系统的整体可用性。同时,结合系统实际的运行情况,讨论和归纳在利用马尔可夫建模分析和计算系统可用性的过程中一些影响因子对系统可用性的影响,为核电厂安全级DCS相关可用性设计和分析提供一些参考。
Availability is very critical in the reliability analysis of nuclear power security DCS as a basic parameter.It’s a very important factor to estimate reliability and performance for nuclear power security DCS.This paper mainly computes and analyzes availability of the RTS which uses the 2oo3 architecture by markov method.Meanwhile, discussing and summarizing effects of some factors existing in the process of the analysis on availability of the system according to actual work condition of the system,and providing the availability analysis and design of nuclear power security DCS with references.
