unstable equilibrium point

基本解释

A transient angle unstable mode of power system closely relates to a controlling unstable equilibrium point (UEP).
电力系统暂态功角失稳模式同相关不稳定平衡点密切相关。
The physical meanings of stable and unstable manifolds on a controlling unstable equilibrium point in electric power system are introduced.
介绍了在不稳定平衡点上的局部稳定和不稳定流形对应于电力系统稳定性问题中的物理含义。
In other words, the unstable limit cycle will be bifurcated from the original asymptotical stable equilibrium point at another higher series compensation level, and the system dynamics will change.
换句话说，在另一较高的串联补偿度上，轨道不稳定的极限环将从原来渐近稳定平衡点上分岔出来，系统的稳定性态将被改变。

不稳定平衡点
The linear boundary of dynamic security region of the controlling unstable equilibrium point was determined on the basis of dynamical system theory. Then, Edgeworth series expansion based on semi-invariant was employed to calculate the weighted joint probability distribution.
3.为避免确定性暂态稳定分析结果过于保守与不全面等问题,以安全域概率稳定模型为基础,基于动力系统理论确定电力系统暂态稳定主导不稳定平衡点附近的动态安全域线性边界,并采用以半不变量为基础的埃奇沃斯级数展开获得随机变量加权的联合概率分布,从而构建电力系统暂态稳定概率模型。
