摘要
为解决普通PID对风力发电机输出功率控制不稳定的问题。针对整个风力发电系统的非线性特点提出了模糊自适应PID变桨距控制的方案。以输出功率值与额定功率值的偏差以及偏差的变化率作为模糊控制的输入,把模糊推理出的三个整定参数和初始PID参数进行叠加后控制变桨距,最后在Matlab/Simulink上搭建整体模型并仿真得到输出功率波形。结果表明:模糊自适应PID比普通PID能更好提高输出功率的稳定性。
To solve the unstable problem of output power control of wind turbine by ordinary PID.Aiming at the nonlinear characteristics of wind turbine system,a fuzzy adaptive PID pitch control scheme is proposed in this paper.Deviation from the output power and the rated power value and rate value of the deviation are used as the input of the fuzzy control,adding the fuzzy parameters and initial PID parameters to control the pitch.Finally,the whole model is built on Matlab/Simulink and the output power waveform is obtained by simulation.
