Fuzzy Optimization Method for Selection Scheme of Normal Water Level of Reservoir Based on Fuzzy and Principal Component Analysis*

摘要

Focusing on the problem of optimization method for selection of normal water level of hydropower station reservoir the generating method of normal water level of reservoir and the select method of evaluating indicator was analyzed. The fuzzy and principal component analysis of selecting normal water level of the reservoir was also provided through combined the relative membership with principal component analysis. The results of the example showed that the method is simple and can reduce greatly computational eff ort of comprehensive evaluation and so can accurately optimize the reasonable normal water level scheme of reservoir.
