【摘要】：随着国家对风电产业的大力扶持，国内风电投资呈现迅速增长的趋势，并涌现出大量的风电制造商。由于不同制造商生产的风机单机容量、技术参数各不同，其容量、造价和运行特性也不同，这给风机选型带来了很大困难。发电机组设备选型作为风电场工程建设中比较重要的环节，其投资占风电场总投资的70%左右。风力发电机组的选型不仅关乎到风电场建设造价，还影响投产后的发电量和运营成本，以及最终的上网电价。因此，在风力发电场设计和建设中，风力发电机组的选型具有十分重要的意义。本文主要研究了以下内容：首先介绍了课题研究的背景与意义，以及国内外研究现状。其次介绍了价值工程的相关理论，研究了功能系数F、成本系数C以及价值系数V的确定方法。然后，结合风力发电机组的功能特点，建立了较为完整的适用于风机选型方案评价的功能指标体系，采用层次分析法确定功能指标的权重值，并通过专家打分得出了功能系数；同时，以风机特定度电成本来计算各机型的成本系数，从而得出价值系数。最后，将上述方法应用于小东梁风电场的三个备选机型的评价中，并计算得出了最优方案，且最优方案与企业最终选择一致。通过运用以价值工程为基础构建的风电场发电机组选型评价模型，为发电机组选型提供了科学依据，具有普遍参考价值，，有利于发电机组选型理论的发展。合理的选择发电机组，将会对于风电场的设计和建设产生积极影响，也会为经济发展提供有力保障。
[Abstract]:With the strong support of wind power industry, domestic wind power investment is increasing rapidly, and a large number of wind power manufacturers emerge. Because the single machine capacity of fan produced by different manufacturer is different, the technical parameters are different, its capacity, cost and operation characteristic are also different, which brings great difficulty to the selection of fan. As an important link in wind farm construction, generator equipment selection accounts for about 70% of the total investment of wind farm. The selection of wind turbine not only relates to the construction cost of wind farm, but also affects the power generation and operation cost after putting into production, as well as the final electricity price. Therefore, in the design and construction of wind farm, the selection of wind turbine is of great significance. The main contents of this paper are as follows: firstly, the background and significance of the research are introduced, as well as the current research situation at home and abroad. Secondly, the related theory of value engineering is introduced, and the determination method of function coefficient F, cost coefficient C and value coefficient V is studied. Then, combined with the function characteristics of wind turbine, a relatively complete function index system suitable for the evaluation of fan selection scheme is established, and the weight value of the function index is determined by AHP, and the function coefficient is obtained by expert scoring. At the same time, the cost coefficient of each type is calculated by the specific power cost of the fan, and the value coefficient is obtained. Finally, the above method is applied to the evaluation of three alternative models of Xiaodongliang wind farm, and the optimal scheme is calculated, and the optimal scheme is consistent with the final choice of the enterprise. By using the evaluation model of wind farm generator selection based on value engineering, this paper provides a scientific basis for the selection of generator sets, which has universal reference value and is conducive to the development of the theory of generator selection. Reasonable selection of generator sets will have a positive impact on the design and construction of wind farms, and will also provide a strong guarantee for economic development.
