摘　　要：针对水轮机调节系统综合评价不够全面,无法综合反映系统多指标、多层次的复杂性问题,提出了基于模糊层次分析法(AHP)-决策与实验室评估法(DEMATEL)-云模型的水轮机调节系统综合评价模型。首先建立基于主要设备和相关工况的多层次指标体系,采用模糊AHP计算评价指标的初始权重;通过DEMATEL法计算评价指标的相互影响与参照关系,绘制出指标因果关系图,并结合初始权重计算评价指标的综合权重;引入云模型得到评价指标各等级的隶属度矩阵。最后将权重结果与隶属度结合,得到系统综合评价等级。算例分析表明,该方法可高效快捷地对水轮机调节系统运行状态进行客观评价,为状态检修提供参考依据。Comprehensive evaluation of hydraulic turbine regulation system is not comprehensive enough and cannot comprehensively reflect the complexity of the multiple indicators and levels of the system,so a comprehensive evaluation on hydraulic turbine regulation systems based on the fuzzy analytic hierarchy process(AHP)-decision and laboratory evaluation method(DEMATEL)-cloud model was proposed.Firstly,a multi-level index system based on major equipment and relevant working conditions was established,and the initial weight of evaluation indexes was calculated by fuzzy AHP;the mutual influence and reference relationship of evaluation index was calculated by DEMATEL method,and the index causal relationship diagram was drawn,and the comprehensive weight of evaluation indexes was calculated in combination the initial weight;the membership degree matrix of each level of evaluation index was obtained by introducing cloud model.Finally,the weight results were combined with the membership degree to obtain the comprehensive evaluation grade of the system.The case analysis showed that this method can make an objective evaluation on the operation status of hydraulic turbine regulation system efficiently and quickly,providing a reference basis for state maintenance.
