不同偏航条件对风力机振动及功率的影响研究

In this paper, a dynamic rotating platform for wind turbines is designed, and the rotating platform is manufactured according to the design scheme. The running program is written by the BASIC language, and the start time of the tested signal is calibrated by the photoelectric sensor. The platform system can dynamically simulate the yaw process of wind turbines, which is more suitable for the actual operation of wind turbines.Using a dynamic rotating platform, the effects of yaw speed and yaw delay time on wind turbine vibration and power were studied. It was found that during the yaw process, the vibration of the wind turbine showed that the slower the yaw speed, the faster the vibration acceleration value increased. The delay time can reduce the vibration acceleration value during the yaw process. When the yaw angle of the wind turbine is 30^◦, the vibration acceleration value in the Y direction decreases by 0.457 m/s² after adding the delay time. And it is found that the faster the yaw speed, the greater the influence of the delay time. Finally, a comprehensive analysis of the vibration and power of the wind turbine during the yaw process is carried out. The yaw speed that takes into account high output power and low blade damage is obtained, which provides direct and important experimental basis and new ideas for wind turbine operation safety and yaw control strategy.
