Matrix_Pencil
- 出一种实现不同维间估计结果自动配对的二维频率估计算法。首先把二维频率估计问题转化成两个矩阵束的特征值问题。根据矩阵束的特征求出两个矩阵束的公共特征向量,并以此为基础同时求出两个矩阵束的特征值。算法估计误差与现有算法相近,但解决了现有算法普遍存在的配对难题。 -Matrix pencils play an important role in numerical linear algebra. The problem of finding the eigenvalues of a pencil

9节点系统小干扰稳定分析
- 对电力系统小干扰稳定性进行分析的方法大致可以分为以下几种:数值仿真方法、建立在线性模型基础上的分析方法、小干扰稳定域分析方法、非线性理论分析方法和计及模型不确定性的分析方法。对小干扰稳定性问题可以采用线性模型进行研究,这种线性模型是将描述系统动态行为的微分方程和代数方程在稳态运行点处线性化后得到的。目前,建立在线性模型基础上的电力系统小干扰稳定性分析方法主要有两种:以状态空间模型描述为基础的特征值分析法和以传递函数矩阵为基础的频域分析法。本文采用全部特征值分析法(QR 法)对9节点系统在稳态处进
