摘要：

在动态入流条件下，采用基于致动线模型的大涡模拟方法对一台1.5 MW的商用风力发电机组的转速、转矩以及输出功率的响应特性进行数值模拟.在对数风廓线模型的基础上，通过引入正弦波动获得动态入流边界条件.对风力机引入比例积分变桨距控制和转矩控制，实现对动态入流的追踪.研究结果表明，在当前的变桨距控制和转矩控制条件下，风力机的转速、转矩、输出功率能够很好地响应入流风速的变化.在风加速阶段，三者都在额定风速时达到额定值；当入流风速减到额定风速后，变桨距控制以及转速、转矩、功率的下降都存在10 s的延迟；模拟得到的功率曲线与风力机实际功率曲线整体上吻合良好，不过在风速小于9 m/s的区间段还存在着一定的偏差，有待于进一步优化.
Abstract:

The response characteristics of speed, torque and output power of a 1.5 MW commercial wind turbine were simulated based on the large eddy simulation with actuator line method under dynamic inflow condition. On the basis of the logarithmic wind profile model, the sine wave was introduced to develop the dynamic inflow boundary condition. The proportional-integral pitch control and torque control were adopted for the wind turbine to track the dynamic inflow. Results showed that under the effect of pitch control and torque control, the speed, torque and output power of the wind turbine responded well to the change of the inflow wind speed, and all of them reached their rated values at the rated wind speed during the wind acceleration phase. There was a delay of 10 s for the pitch control and the decline of speed, torque and power after the inflow wind speed reduced to the rated value. The simulated wind turbine power curve agreed well with the actual power curve in general, but there was still a certain deviation when the wind speed was less than 9 m/s, which needs further optimization.
