中文摘要
      近年来发展起来的互补群群际能量壁垒准则(CCEBC), 是普适于非自治非线性运动系统稳定性分析的量化方法, 已经在国内外电力系统的工程中得到了广泛应用. 本文应用CCEBC对质点弹簧系统在大扰动下动态行为的稳定性进行了定性和定量分析, 给出在不同的扰动清除时间下的轨迹稳定裕度和参数的稳定极限, 分析了系统失稳模式随参数(例如扰动清除时间)而变的机理. 研究结果证明CCEBC稳定性量化理论不但适用于电力系统, 也适用于任何多刚体运动系统.
英文摘要
      The CCEBC(complementary cluster energy barrier criterion)theory, recently developed for transient stability assessments of power systems, is rigorous and quantitative. It has been widely used in power system engineering projects at home and abroad. In this paper, CCEBC is applied to particle spring systems to study their motion stability under large disturbances. The stability margins of disturbed trajectories are investigated and the nature of that the unstable mode varies with the disturbance clearing time is also uncovered. Study clearly shows that quantitative stability analysis is much more advanced than qualitative analysis, and CCEBC is valid not only for power systems, but also for other motion systems.
