例句与用法

According to these theories we know the reason of the emergence of low frequency oscillation is lacking positive damping even appearing negative damping . this problem can be classified as dynamic stability
从而得出，电力系统低频振荡是由于系统正阻尼不足甚至产生负阻尼而引起的，可以将其归类为动态稳定问题。
Those sensitive parameters making system have negative damping and occur self - excited shimmy are horizontal pulling lever rigidity , tire sideslip rigidity , steering gear rigidity and damping , kingpin equivalent damping , kingpin caster angle , tire drag . and wheel center distance , tire side rigidity , vehicle wheel unbalanced mass , tire vertical rigidity , and distance from kingpin center to the vertical central line plane of tire have great influence on shimmy , but they do n ' t make the system have negative damping . and horizontal pulling lever damping , suspension damping and rigidity have very small influence on shimmy
横拉杆刚度、轮胎的侧偏刚度、转向机刚度、转向机阻尼、绕主销当量阻尼、主销后倾角、轮胎拖距是影响摆振的敏感性参数，适当调节某一参数可引起系统的负阻尼，使系统产生自激摆振；轮距、轮胎侧向刚度、车轮上的不平衡质量、轮胎垂向刚度及主销延长线与地面交点至车轮平面的距离对摆振的影响也较大，但不会使系统出现负阻尼；而横拉杆阻尼、悬架阻尼与悬架刚度对摆振的影响很小。
Torsional interaction exists between hvdc converters and turbine - generators , and negative electrical damping provided by hvdc may cause subsynchronous oscillation ( sso ) that can lead to turbine - generator shaft failure and electrical instability at oscillation frequencies lower than the fundamental system frequency
高压直流输电( high - voltage - direct - current - - - - hvdc )系统与临近同步发电机组之间存在着扭振相互作用， hvdc的电气负阻尼作用有可能引起机组在次同步频率范围的扭转振荡。
Through the deep study of f . d . demello dynamic model of electromechanical transition and synchronous generator theory , we proposed a new control strategy of excitation device that can eliminate the negative - damping phenomenon , which is directly against the cause of producing negative - damping represented as low frequency oscillation in the system
通过深入研究f . d . demello机电暂态的动力学模型以及同步发电机理论，针对系统产生负阻尼即低频振荡的原因，我们提出了一种新的可消除负阻尼现象的励磁控制策略。
On the contrary , because of the effect of positive damping provided by the inverter , the unit near a inveter will have no subsynchronous oscillation risk . based on the same method described above , a damping study is carried out for a hybrid ac / dc system , which include a hvdc link and an ac transmission line in parallel
研究表明，系统整流站附近的同步发电机组要承受电气负阻尼作用，因此有可能引起机组低频扭转振荡模式失稳；而hvdc的逆变站向其临近同步发电机组提供正阻尼，因而机组不存在次同步振荡危险。
The characteristics of damping shows that the uncompensated parallel ac transmission line can release the coupling between the hvdc and generator and improve the damping of the system , hence the possibility of subsynchronous oscillation decrease . in such a system scheme , the hvdc system dominates the changes of damping due to the small magnitude of the damping provided by ac line . when the ac transmission line is compensated with a fixed series capacitor , the situation will be totally different
其中，并列运行的无串补交流输电线路可以缓解hvdc与其临近机组之间的机电耦合程度，改善hvdc的电气负阻尼特性，从浙江大学博士学位论文摘要而减轻机组发生次同步振荡的危险性，此时系统的整体电气阻尼特性由hvdc的性质决定;但若交流线路中存在串联补偿电容，则系统幅值较大的电气负阻尼不仅可能使整流站机组发生次同步振荡，逆变站附近机组同样存在发生次同步振荡的可能性，此时系统的整体阻尼特性由串联补偿电容的性质决定。
