| 摘 要： | 针对风力发电机组的风向变化绝对值(偏航角度)小于15°的风能捕获率问题,提出一种在不使用风向标传感器的情况下,采用陀螺仪和爬山算法相结合的方法来控制偏航机构,能够准确地采集到风向信号,快速调节机舱的偏转角度,使风力发电机风轮法线方向与变化的风向始终保持一致,实现最大捕获风能的控制策略。通过LabVIEW仿真软件对1.5MW的风力发电机在输入变化的风向信号时,功率和偏航电机动作进行仿真分析,结果表明该策略能够使风力机的输出有效功率增加,使得机舱具有对风快,平稳的特点。

| Abstract: | In order to solve the wind turbine of wind change in the absolute value (yaw angle) problem of less than 15 degree wind energy capture rates,a wind vane sensors are presented without the use of cases,combining with gyroscopes and hill-climbing algorithm to control the yaw institutions,can accurately capture the wind direction signal,rapid-conditioning the cabin of the deflection angle,so that wind generators wind wheel normal direction of the wind direction and change is always consistent for maximum captur... |
