摘　　要：风电场并网容量不断扩大,被并入电网的调度控制及稳定运行都需要准确的功率输入信息。考虑机组间尾流效应,诸多因素都会对尾流效应的强弱产生改变,如:风机排列位置、间距、地势、风向、风速等。综合考虑以上因素,运用MATLAB仿真软件对影响机组间尾流效应的因素进行仿真分析,得出不同因素作用下对风电场风速分布及功率输出能力的影响,建立了复杂情况下的尾流效应模型。提出尾流影响系数的概念,定量分析尾流效应对风场出力的影响。所得结果可为风电场选址建设以及区域风能分布预测提供参考。With the grid capacity of wind farm expanding constantly, the scheduling control and the stable operation which is incorporated into the grid need accurate information of input power. Considering wake effect of the u- nits, many factors may change the intensity of the wake effect, such as the position, distance, topography, wind direction, wind speed of the units and so on. Taking the above factors into consideration, the model of the factors which in- fluence wake effect in the units is established by using the software MATLAB. There are simulation and analysis of the wind field distribution and the function of output power with different factors. Also, the model of the wake effect is established under complex conditions. A concept of the influence coefficient of wake effect is proposed, quantitative a- nalysis of the effect by wake effects on wind farm output is made. The simulation results can provide reference for selection and construction of wind farm and the prediction of regional wind energy distribution.
