Liquid-Driven Wind Turbine Speed Linearisation Control and Optimisation Study
The wind speed sensor monitors the wind speed in real time and transmits it to the controller,which is combined with the quantitative pump speed state to calculate the wind turbine model to track the results and achieve the effect of precisely regulating the variable motor speed.The research results show that,whether under steady speed or variable speed,the motor speed dynamics show a stable change rule,the overall fluctuation in the 1 500 r/min up and down,indicating that the results of the test is accurate.Under steady speed,before and after adding throttle valve to adjust the speed,the motor speed output fluctuation is reduced from±5 r/min to±2 r/min;under variable speed,before and after adding throttle valve to adjust the speed,the motor speed output fluctuation is reduced from±15 r/min to±5 r/min,which is of high control stability.This research has good theoretical significance to improve the operation stability of wind power equipment,and is easy to promote the application.
