| 摘 要： | 针对影响风电场机组功率输出的问题,通过实地考察,选择合适位置安放测量装置,并结合GB/T 18451.2—2003 功率特性测试标准进行测试研究,分析不同区域内的风速和风功率输出特性。结果表明:风电机组之间的尾流效应,降低了风电机组的风能利用系数,影响了风电机组的功率输出;因此,在建设风电场时,应充分考虑风电机组之间的距离,尽量减少尾流效应对风电机组的影响。

| Abstract: | Aiming at the problem of influencing the power output of wind power generation units inwind farm, by spot investigation and selecting the proper position to place the measuring instruments,and combing with GB/T 18451.2 -2003 power characteristic test standard, makes test research,analyzes wind speed and wind power output characteristic in different area. The result shows that thewake effect between the wind power generation units can reduce the wind energy utilization coefficientof the wind power units and effect on the power output of the wind power generation units. Thereforeduring the wind farm construction, must take a full consider the distance between wind power units,reduce the influence of wake effect as far as possible. |
