【摘要】：火力发电过程中会产生大量废气、废水、废渣，对大气和水环境造成了严重污染。并且煤炭资源具有稀缺性，一旦枯竭，短期内不可再生。所以利用可再生能源发电受到世界的重视。其中风力发电技术较成熟，技术性能优越，是近些年发展最快的一种可再生能源发电技术。利用风能发电建设风电场的基础工作之一是确定适合该风电场的风电机组型号。风电机组是风电场的主要设备，其投资约占风电场总投资的60%-80%。风力发电机组选型对风电场的年发电量和经济指标具有重要的意义。而随着国内风机制造企业的不断增多，技术路线不同、性能参数各异的风电机组机型层出不穷，使风机选型工作更加复杂与重要。本文主要对陆地风电场的风机选型进行研究。本文运用层次分析法进行陆地风电场风机选型研究。对国内外文献进行梳理后发现目前实际风机选型工作中的选型方法大多是沿用上世纪90年代提出的技术经济比选法。风机选型工作中要对各方面因素综合考虑，但各种因素对选型工作的重要程度不同，，应在其权重中体现出来，这对风机选型工作乃至整个风电场建设项目能否建设成功并投入运营有重大影响。但经济比选法忽略了不同风机选型影响因素的权重差别，已经不适应当前的风机选型工作。本文建立了普遍适用的陆地风电场风机选型指标体系，运用层次分析法对各风机选型因素科学赋权重，进行陆地风电场风机选型研究。以国内某陆地风电场为例，验证了运用层次分析法进行风机选型的适用性。本文得出结论：本文建立的陆地风电场风机选型指标体系具有普遍适用性；运用层次分析法为风机选型影响因素赋权重具有科学性和适用性；将层次分析法运用于风机选型工作中具有一定的可行性，能为实际工程建设中的风机选型提供参考。
[Abstract]:A large number of waste gas, waste water and waste residue will be produced in the process of thermal power generation, which will cause serious pollution to the atmosphere and water environment. And coal resources are scarce, once exhausted, non-renewable in the short term. Therefore, the use of renewable energy to generate electricity has been attached importance to by the world. Among them, wind power generation technology is more mature, technical performance is superior, is the fastest development of renewable energy power generation technology in recent years. One of the basic tasks of using wind power to build wind farm is to determine the type of wind turbine suitable for the wind farm. Wind turbine is the main equipment of wind farm, and its investment accounts for about 60% of the total investment of wind farm. The selection of wind turbine is of great significance to the annual power generation and economic index of wind farm. With the increasing number of domestic fan manufacturing enterprises, wind turbine models with different technical routes and different performance parameters emerge in endlessly, which makes the fan selection more complex and important. In this paper, the selection of fans in land wind farms is studied. In this paper, the analytic hierarchy process (AHP) is used to study the selection of fans in land wind farms. After combing the literature at home and abroad, it is found that most of the selection methods in the actual fan selection work are based on the technical and economic comparison and selection method put forward in the 1990s. In the work of fan selection, all kinds of factors should be considered comprehensively, but the importance of various factors to the selection work is different, which should be reflected in its weight, which has a great influence on the success of fan selection work and even the whole wind farm construction project and put into operation. However, the economic comparison method ignores the weight difference of different influencing factors of fan selection, and is no longer suitable for the current fan selection work. In this paper, a generally applicable index system for fan selection in land wind farm is established, and the selection factors of each fan are scientifically weighted by analytic hierarchy process (AHP), and the selection of fan in land wind farm is studied. Taking a land wind farm in China as an example, the applicability of AHP in fan selection is verified. In this paper, it is concluded that the fan selection index system established in this paper has universal applicability; the application of analytic hierarchy process (AHP) to weigh the influencing factors of fan selection is scientific and applicable; and the application of AHP to fan selection is feasible, which can provide reference for fan selection in practical engineering construction.
