基于马尔科夫过程的核电厂DCS可靠性分析方法

Analytical method of the reliability of DCS in nuclear power plant based on Markov processes

对核电DCS的可靠性进行了分析,利用马尔科夫过程建立了一个数学模型。并初步利用建立的模型对三个核电厂的可靠性参数指标进行了计算。结果表明:所建模型正确、可靠、误差率仅为9×10-10,适用于核电厂DCS可靠性的初步分析。

This paper analyzes the reliability of DCS in nuclear power plant and establishes a mathematical model by Markov processes which is applied to initially calculate the parameters and index of reliability in three nuclear power plants.Calculation result proves the accuracy,reliability and low error rate of the model,which is 9×10-10.Therefore,the model applies to the initial analysis of the reliability of DCS in nuclear power plant.
