摘要
以考虑尾流效应的并网风电场等值建模作为研究对象,由于尾流效应的影响,造成不同位置处的风力机捕获到的风速不同,通过Jensen模型和风向等因素提出了1种求风力机平均风速的方法。为了节约仿真时间和反应尾流效应的影响,将风电场等效为1台风力发电机组,输入为等效平均风速。最后通过在Matlab/Simulink中建立仿真模型,结合风速扰动和电网故障来进行研究,证明了模型的正确性和有效性。
This paper takes grid-connected wind farm equivalent modeling as research object with considering wake effects.The wind turbine at different locations can capture the different wind speeds due to the influence of wake effects.Through Jensen model,wind direction and other factors,this paper proposes a method for the average wind speed of wind turbines.In order to save the simulation time and the influence of wake effect,wind farm is equivalent to a wind turbine and the equivalent mean wind speed is taken as input.Finally,this paper constructs the simulation model in Matlab/Simulink,and proves the correctness and validity of the model through studying wind speed disturbances and power grid fault.
