摘要
针对变桨距风力机存在非线性、时变性、抗干扰性和滞后性等问题,在分析风力发电机组系统特性和变桨距控制要求的基础上,建立了风力发电机的数学模型,并对变速恒频风力发电机组在低于和高于额定风速运行时的变速桨距调节分别设计了两个模糊控制器,最后在Matlab/Simulink仿真软件上利用SimPower-Systems模块进行仿真.仿真结果表明本方法有效、可行.
In order to solve the problems of non-linear, time-varying, anti-disturb and time-lag, the mathematical model of variable pitch control system is established after analyzing the characteristics of wind turbine generator system and the requirement of pitch control; the two fuzzy controllers are designed for the control system of VSCF wind turbine when the wind speed is lower or higher than the rated wind speed. Finally, the proposed system is simulated on SimPowerSystems modules of Matlab/Simulink simulated software, the simulated result shows availability and feasibility of the method.
