【摘要】 在全球的新能源和可再生能源行业中,风能凭借其巨大的环保效益和商业潜力,得到快速发展。风力发电场微观选址与风机选型是整个风电场建设的重要环节,是风电项目综合评估的根本,是决定风电场建设取得良好效益的关键。目前我国已建的部分风电场出现了容量系数偏低、发电量不足、机组故障频发等各种问题,究其根本原因之一就是微观选址与机型不匹配。本文从研究风资源和风特性着手,深入讨论了风剪切、湍流、尾流等对风力发电机组载荷和疲劳的影响及风力发电机组的主要技术性能指标,介绍了Meteodyn WT风资源CFD软件的理论基础和求解方法,建立了以风力发电机组容量系数和风力发电机组排列间距为约束、以风电场发电量为目标的数学模型,给出了在进行风电场风能资源评估的具体操作步骤。结合企业的实际情况,针对罗平山风电场一期工程,按照所给出的风电场风资源评估的具体操作步骤,通过Metodyn WT软件进行风资源综合评估,利用所建立的数学模型,实现了风电场微观选址和选型的优化,得到了业主的认可。本文在微观选址和选型优化方面的综合研究,为在风电场建设初期,如何提高风电场的年发电量、确保风力发电机组的可靠运行提供了有益的措施、建议并给出了实施的具体步骤,对建设新的风电场具有有益的参考价值及一定的现实意义。更多还原

【Abstract】 In the global new energy and renewable energy industry, wind energy develops rapidly because of its environment protection benefits and commercial potential. Wind farms micrositing and wind turbine options is the key link of the whole wind farm construction, the basic of the wind farm general evaluation, and the crucial issue for favorable benefits. At present, all kinds of problem have turned out in our country, such as the lower capacity factor, insufficiency generating capacity and frequently faulty occurring of WECS (Wind Energy Converter System). One of the basic reasons is the site and WECS mismatching.From the beginning of wind resources studying, this paper deeply discuss the influences of wind shear, turbulence, wake flow on wind turbine and the technique, performance index of WECS, introduce technical basis and methodology of Meteodyn WT CFD software, establish a mathematical model in which generating capacity is the object, WECS capacity factor and space is the restriction, finally provide detailed operating steps in the wind resources assessments of wind farms.Combine the actual situation of enterprise, use CFD software of Metodyn WT and the mathematical model, this paper implement micrositing and wind turbine options optimal arrangement to the Luopingshan wind farm project phase one according to the providing detailed operating steps in the wind resources assessments of wind farms.The comprehensive study for wind farms micrositing and wind turbine options of this paper advises useful measures, suggestion for improve wind farm generating capacity and assure reliability service of WECS and also provide detailed operating steps. It provides reference for building new wind farm and has practical significance.更多还原
