The responses properties of coupled vibrations for 120° and 180°asynchronous juxtaposition of 200MW turbine-generator set were analyzed. The results show that the responses properties of flexural and torsional vibrations caused by 120° asynchronous juxtaposition are similar to that of 180° asynchronous juxtaposition. When the fault happened, Former two steps inherence frequencies and whirl speed frequency of torsion are excited. And the first step inherence frequencies of flexural vibration are also excited besides whirl speed frequency. Transient electromagnetism moment peak, torsional and torsional moment responses caused by 180° asynchronous juxtaposition are lower than that of 120° asynchronous juxtaposition.
利用该方法,针对某200MW汽轮发电机组的120°和180°两种非同期并列情况,进行了机组弯扭耦合振动响应特性研究,分析表明:汽轮发电机组的120°和180°两种非同期并列情况下的弯振和扭振响应特性基本相似;非同期并列主要激发出工频和前两阶固有频率扭振,弯振除工频主分量外,第一阶固有频率也被激发出来;180°非同期并列时的暂态电磁力矩峰值比120°非同期并列时低,相应的扭振和扭矩响应也小于后者。
