Automatic Control Method of Independent Variable Paddle of Wind Turbine Based on Improved Ant Colony Algorithm
The traditional variable paddle control method can not better cope with the complex and changeable wind power environment.Therefore,an independent variable paddle automatic control method of wind turbine based on the improved ant colony algorithm is proposed and designed.First of all,the generator pitch model is established based on the improved ant colony algorithm,and the adaptive adjustment strategy of the improved ant colony algorithm is selected to enhance the local search ability.Secondly,calculate the load of wind turbine,according to some rules of each blade pitch angle,thus reduce the uneven load.Finally,the independent blade desired pitch angle and unified pitch a given pitch angle superposition,realize automatic control of wind turbine independent pitch.The results show that the independent paddle automatic control method of wind turbine based on the improved ant colony algorithm is consistent with the effective wind speed fluctuation corresponding to the optimal wind energy utilization rate in terms of controlling the effective wind speed.Compared with the traditional method,the former method can effectively restrain the fluctuation of the effective wind speed of the wind wheel.
