基于层次分析法的风电场风机选型研究

针对目前工程上风机选型时对大部分定性因素考虑较少，导致所选出的风机无法保证整个风电项目经济效益达到最佳的问题，对国内外风电场在建设和运营过程中出现的风机选型问题进行归纳和总结，提出影响风电场风机选型的主要因素。在风机选型中，运用层次分析法建立层次分析结构模型和判断矩阵，计算各元素权重系数并检验判断矩阵一致性结果，从中选出综合评价最优的备选机型。通过工程实例应用表明，将层次分析法运用于风机选型具有一定的可行性，整个选型过程更为科学、合理，选型结果具说服力。

Research on Type Selection of Wind Turbine for Wind Farm Based on Analytic Hierarchy Process

Aiming at lack of consideration of most qualitative factors in type selection of wind turbine which results in failure of utmost economic benefit of the wind power project,the paper summarizes and concludes type selection of wind turbines in construction and operation of wind farm both home abroad.It proposes major factors influencing type selection of wind turbine.In type selection of wind turbine,analytic hierarchy process is used to analytic hierarchy structure model and determination matrix;weight coefficient of each factor is calculated and conformity of determination matrix is checked to select the best turbine in respects of various evaluations.It is proved by engineering application that it is feasible to apply analytic hierarchy process in type selection of wind turbine;the process of type selection is more scientific,reasonable and the result is more persuasive.
