Comprehensive Maintenance Effect Evaluation of Hydroelectric Generating Unit Based on Hierarchical Analysis Process and Improved Fuzzy Evaluation Method
In order to comprehensively evaluate the maintenance effect of hydroelectric generating unit,a comprehen-sive maintenance effect evaluation model of hydroelectric generating unit based on analytical hierarchy process(AHP)and improved fuzzy evaluation method is proposed by considering the changing work conditions of the unit.Firstly,a compre-hensive maintenance effect evaluation index system is established according to actual unit.Then,combined with the AHP subjective weight determining method and the Critic method,a weight comprehensive calculation model is constructed to obtain the comprehensive weight of the indicators in each layer of the evaluation index system.After that,a method for e-valuation index quantization is investigated,and the quantized evaluation index is applied to the fuzzy evaluation model,the fuzzy evaluation matrix of each index is solved,and the comprehensive score before and after the maintenance of hy-droelectric generating unit is given.Finally,taking an actual hydroelectric generating unit as an example,the effective-ness of the proposed method is verified according to the acquired data under multiple working conditions.
