wind speed fluctuation

The wind speed model considering wake effect can describe power output of wind farm more accurately under wind speed fluctuation, therefore the study result is more practical.

考虑风电场内机组间尾流效应的风速模型能较准确地描述风速扰动下风电场输出功率的波动，使研究结果更具有实际意义和价值。

The simulation model and result are given under the environment of MATLAB. The fluctuation of wind speed can be controlled and the disturbance can be cancelled by BP neural network controller.

在MATLAB环境下给出了用BP网对变速风力发电机控制的仿真模型和仿真结果，显示采用神经网控制器控制有很好的抗风速突然波动的作用，能有效地抑制扰动。

The intermittent and random fluctuation of wind speed result that wind power grid-connected power fluctuates largely, which has a negative influence to stability and economy of power grid operation.

由于风速具有随机波动性，因此风力发电并网功率波动很大，这对电网运行的稳定性及经济性带来负面影响。
