摘　　要：分析了模糊评估模型的构建原理,应用模糊映射和灰色关联理论构建了模糊综合评估理论模型,提出了无人值守变电站维修性评估灰色关联度建模和计算方法,给出了220kV无人值守变电站维修性评估实例.结果表明,采用二级分层模型,可以显著降低多因素评估的计算复杂性,高效地实现目标评估.The construction principles of the fuzzy evaluation model are researched. The fuzzy comprehensive evaluation theory model is established based on the fuzzy mapping and grey relation theory. A unattended substation maintainability evaluation gray relation modeling and calculation method are proposed. A unattended substation of 220 kV maintainability evaluation is given as an example. The results show that by using the two-layered model, the computational complexity of multi-factor assessment can be sig- nificantly reduced and the objective assessment can be efficiently implemented.
