振荡模式 meaning in Chinese
mode of oscillation
oscillation mode
Examples
- In order to overcome these problems , the prony method based on angle measurement technology is used . it " s ability to estimate the frequency , damping and strength of modal components would be quite valuable to power system research . 2
据此研究使用prony方法直接分析测量信号、提取特征振荡模式的方法，并结合前后两种方法分析两者之间的联系，从理论上分析了prony方法的有效性。 - Some fundamentally influential factors such as systemic structure , the distribution of power flow , effects of excitation system and pss , as well as characteristics of load models , etc , are discussed in detail to study the systemic damping
随后从系统结构、潮流分配方式、励磁系统和电力系统稳定器的作用以及负荷特性等角度，详细讨论了影响互联系统振荡模式阻尼的因素，并研究了这些因素的相互作用。 - 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。 - Chapter 4 presents a detailed analysis of low frequency inter - area oscillations of the south china interconnected power system for the year of 2005 based on the eigenvalue analysis method . participation factors and mode shape diagrams of generators related to the inter - area oscillations are figured out , and locations of pss are determined accordingly , the parameter setting for the pss is studied as well
采用特征值分析法详细分析了2005年夏大运行方式下南方电网的低频振荡特性，计算了对应主要振荡模式的发电机参与因子和模态分布图，并根据参与因子的大小研究了南方电网的pss配置方案及其参数整定。
