通过分析核电站数字化报警系统的功能和特点,结合国内外核电站的实际情况,建立了基于灰色理论的核电站数字化主控室报警系统评价指标体系,为核电站数字化报警系统的综合评价奠定了基础.评价过程中采用灰色统计方法建立了模糊评价矩阵,利用灰色关联度分析法确定了评价指标的权重,建立了基于灰色理论和模糊数学的综合评价模型.最后,通过案例实证分析,表明该方法用于核电站数字化报警系统评价是一种有效的方法.
The paper analyzes the function and characteristics of digital alarm system for nuclear power plants, and with consideration on the condition of domestic nuclear power plant, all of which formed an objective evaluation system. This evaluation system made a foundation for digital alarm system evaluation in nuclear power plant in the process of evaluation, gray statistic method is utilized to establish fuzzy evaluation matrix, and gray relation analysis is utilized to obtain the weights of indexes, then a comprehensive evaluation model based on gray theory and fuzzy mathematics is established. Finally, an application example is given to indicate that the method is a valid evaluative method for digital alarm system in nuclear power plant.
