Hebei Electric Power Design Research Institute, Shijiazhuang 050031, Hebei Province, China; 2. College of Water Conservancy Hydropower Engineering, Hohai University, Nanjing 210098, Jiangsu Province, China) ABSTRACT: The optimal layouts of wind turbine-generator 环节,其中确定各风机在风电场中相对布置位置的 (WTG) in wind farm are influenced by WTG wake when the 主要因素之一是风机间的尾流效应,而且多台风机 site of wind farm is selected. At present, the research 间的尾流迭加又会影响其他受影响风机的工作风 achievements in China and abroad on WTG wake and overlay 速,因此,风机尾流模型及其对应的迭加模型是整 model in actual wind farm mainly focus on one-dimension 个风电场发电量预测的基础[1-3] 。这些模型的合理性 linear model. Aiming to improve the situation, more complete reasonable WTG wake model was constructed and its boundary 以及受其他风机尾流影响的风机工作风速的合理 in wake was nonlinear with the distance. In addition, according 确定,将直接影响风电场的风机布置和发电效益。 to actual circumstance in WTG wake, different fuller WTG 最初,针对尾流情况[4-5],多数学者都是根据经 overlay models were built to adapt to the situation of existing 验给出一些粗略的指标予以指导风电场风机的发 wind farm.
