基于改进AHP及云模型的水轮机调节系统状态评价
Operation status evaluation of hydraulic turbine regulation system based on improved AHP and cloud model
摘要
Abstract
Comprehensive evaluation of hydraulic turbine regulation system is not comprehensive enough and cannot comprehen-sively 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(DEMA-TEL)-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 rela-tionship 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 objec-tive evaluation on the operation status of hydraulic turbine regulation system efficiently and quickly,providing a reference basis for state maintenance.关键词
