Comprehensive Performance Evaluation Method of Hydro-turbine Based on Fuzzy Analytic Hierarchy Method
Aiming at the problems of multi-factor evaluation indexes,lack of reference indexes and fuzziness in direct comparison of operating stability of hydropower project,and fuzziness in direct comparison of turbine op-eration stability,a comprehensive performance evaluation method based on fuzzy analytic hierarchy process is proposed to evaluate the comprehensive performance of multiple turbines of the same type.In this method,the weights of selected indexes are calculated by the analytic hierarchy process,and then the indexes to be evaluated are converted into membership degree and membership function by the fuzzy arithmetic to achieve fractional operation performance of the unit.The evaluation results are in agreement with the actual situation,which ver-ifies the correctness and reliability of the evaluation method.
