摘要
针对典型年选择中定性原则的主观和不确定性,综合主成分分析法和模糊相似优先比法的优点,建立了基于主成分分析的模糊相似优先比法选择典型年的数学模型。以河南省金牛岭水电站为例,先采用主成分分析法从众多相似因子中挑选出主要相似因子,然后利用模糊相似优先比优选出设计典型年,并通过与长系列法计算结果的对比分析,验证了该模型的有效性和可行性。
Aiming at the subjectivity and uncertainty of qualitative principle in typical year selection,combining the advantages of principal component analysis and fuzzy similarity priority comparison method,it builds a mathematical model to choose typical year.Taking Jinniuling hydropower station of Henan Province as an example,principal component analysis is used to pick out the main similarity factor from several factors.And then the fuzzy similar preferred ratio is adopted to optimize the designed typical year.Comparative analysis of the calculation results of long series method,it verifies the validity and feasibility of the model.
