Abstract
The yaw control system of wind turbines is not effective in wind power control.In order to improve wind energy utilization and power generation efficiency,a decision tree is used as a basic algorithm to construct a yaw control system for wind turbines.Firstly,integrate physical device units such as signal acquisition,position servo,yaw transmission,and establish the hardware structure of the yaw control sys-tem.Based on a decision tree algorithm,software control programs for systems such as yaw control rule extraction,impeller side to wind direction,and automatic unwinding are designed,taking into account fac-tors such as hysteresis and mechanical loss.Applying the system to the simulation model of a large wind turbine to conduct testing activities,by comparing the simulation data such as the yaw motor start pulse,generator power,wind turbine speed,and yaw angle before and after controlling the linear increase in wind direction angle,it is found that each parameter has a strong correlation with the wind direction angle.The curve slope of the yaw angle is infinitely close to 1,and has a significant linear relationship with the wind direction angle.The results show that the system can improve the power generation efficiency and yaw con-trol efficiency of wind turbines,and can quickly and accurately achieve yaw control of wind turbines.关键词
