摘要:
风电技术发展速度远高于风电场衰老速度，随着技术的不断进步，多数风电场可以进行有针对性的改扩建，并以此来最大化利用已有风电场内风能资源，增加经济收益。根据已建成风电场运行特性对风电场进行精细化设计是已建成风电场改扩建的关键。针对已建成风电场的Scada数据进行统计分析，了解风电场风能资源特征及运行特性，随后根据风电场风资源特征及运行特性，建立CFD模型，并通过对比风电场模型与风电场各机位点实际测风数据的误差，确认风电场CFD模型的精确程度，最后应用修正为自由流的已建机位点机舱测风数据进行模型修正，达到精准模拟风电场的要求，并以此来确定风电场改扩建排布方案，确保风电场发电量。工程实例的数据与结果分析表明了该方法的可行性。 Abstract:The speed of the technical development of the wind power plant is much faster than that of the deterioration of the wind farm, with the constant progress of the technology, the majority of wind farms can be targeted expansion, and in order to maximize the use of existing wind farms wind energy resources, increase the economy income. According to the characteristics of the built wind farms, the design of the wind farms is the key to the reconstruction of the wind farms. The Scada data of the built wind farms are statistically analyzed to understand the characteristics and operating characteristics of wind energy resources of wind farms, According to the wind resource characteristics and operating characteristics of the wind farm, The CFD model error of the wind farm is confirmed, and the model of the wind farm is revised to meet the requirements of the accurate simulation of the wind farm. The wind farm is used to determine the wind farm expansion plan to ensure that the wind farm Power generation. The results of the engineering examples and the data analysis show the superiority of the method.
