【摘要】：當(dāng)風(fēng)速高于額定風(fēng)速、小于切出風(fēng)速時,恒電機(jī)轉(zhuǎn)矩控制易導(dǎo)致傳動鏈扭矩大幅波動,降低風(fēng)力發(fā)電機(jī)組關(guān)鍵零部件的疲勞壽命。針對該問題建立基于狀態(tài)空間的傳動鏈線性化模型,采用線性二次型調(diào)節(jié)器(LQR)方法設(shè)計風(fēng)力發(fā)電機(jī)的轉(zhuǎn)矩控制器,將傳動鏈一階扭轉(zhuǎn)模態(tài)對應(yīng)的閉環(huán)極點(diǎn)向復(fù)平面的左側(cè)移動,實(shí)現(xiàn)對傳動鏈的動態(tài)加阻。通過Matlab7.1/Simulink中的控制器與FAST風(fēng)力機(jī)模型的聯(lián)合仿真表明該控制方法的有效性,即可提高傳動鏈的阻尼,降低風(fēng)力發(fā)電機(jī)組關(guān)鍵零部件的載荷。
[Abstract]:When the wind speed is higher than the rated wind speed, when the wind speed is less than the wind speed, the torque control of the constant motor will easily lead to a large fluctuation in the torque of the transmission chain and reduce the fatigue life of the key parts of the wind turbine. A linear model of the transmission chain based on the state space is set up, and the linear two order regulator (LQR) is used to design the rotation of the wind generator. The moment controller, which moves the closed loop poles corresponding to the first order torsional modes of the transmission chain to the left side of the complex plane, realizes the dynamic resistance to the transmission chain. The joint simulation of the controller in Matlab7.1/Simulink and the model of the FAST wind turbine shows that the effectiveness of the control method can improve the damping of the transmission chain and reduce the key of the wind turbine generator set.
