H型垂直轴风力发电机的变桨距控制研究

Research on Variable Axis Control Based on H Type Vertical Wind Turbine

H型垂直轴风力发电机的启动性能差、输出功率低很大程度上影响着垂直轴风力机的广泛使用。主要针对H型垂直轴风力发电机,对各模块进行建模并在MATLAB&SIMULINK中搭建其模型进行仿真,对其采用PID控制策略进行变桨,即在不同位置对叶片进行相应的变桨。最后,将采用PID控制变桨后垂直轴风力机的功率曲线与未变桨时进行对比,验证了采用PID控制的优越性和合理性。

To a great extent,the weak of self start-up and output on H type vertical axis wind turbine hindered its widespread use.This paper study H type vertical axis wind turbine,built each module＇s model and simulation by MATLAB.This paper adopts PID control to control the variable pitch,namely,carried on the corresponding variable propeller blade in different position.Finally,it proves the superiority and rationality of PID control by comparing the power curves of adopting PID control variable pitch and fixed pitch.
