兩質量模型資料

1、兩質量模型風力發(fā)電機組的軸系統(tǒng)可以表示由一二質量系統(tǒng)或由一個單一的集中質量系統(tǒng)。在兩質量模型，使用單獨的代表低速渦輪和高速發(fā)電機，與連接的彈性軸被建模為一個彈簧和一個減振器，如圖2所示。機電動態(tài)方程由下式給出t和r分別是風力機、發(fā)電機轉速；Tm和Te分別是風力機的機械轉矩發(fā)電機的電轉矩；Ttg是模型的內(nèi)部轉矩；Ht和Hg分別是風力機和發(fā)電機的慣性常數(shù)，分別；Dt和Dg分別是風力機和發(fā)電機的阻尼系數(shù)；Dtg是柔性軸阻尼系數(shù)； Ktg是軸的剛度系數(shù)。,單質量模型風力機轉速發(fā)電機轉速傳動軸扭矩，固有震蕩園頻率：衰減時間常數(shù)：rs=0.0071;rr=0.005;L1=0.171;L2=0.156;L
