摘　　要： 针对智能变电站自动化系统的新特点,提出了定量评估系统完成任务总能力的有效度模型。首先,搭建由物理网架、逻辑网架和信息流构成的"二网一流"评估平台,在评估指标体系中引入系统有效度作为总指标,其涵盖了可靠性、可用性、实时性和经济性4个宏观指标。接着运用网络层次分析(ANP)法构造典型ANP结构,描述微观指标间的反馈依存关系,并通过判断阵的加权、检验与调整计算网络合成排序。最后的ANP灵敏度分析表明,ANP模型结构稳定,合成排序结果可信度高,决策者能够根据不同的需求做出评估决策。 According to the new characteristics of the smart substation automation system, a model for quantitatively evaluating the capacity effectiveness of the system in task fulfillment is proposed. The evaluation system composed of a physical network architecture, a logical network architecture, and the information flow, or the ＇ two networks one flow＇ platform for short is set up firstly. The effectiveness is defined as the total index which involves reliability, availability, real time and economy in the index system. Then, an analytic network process （ANP） model is developed to describe the complex relationships of influencing factors and calculate the network synthetic rank by the weighting, test and modulation of judgment matrixes. Finally, the stability of the ANP evaluation model and the credibility of scheme rank are tested by the ANP sensitivity analytical method to help evaluation decision-making.
