电网暂态分析是保证电网稳定运行的重要手段。随着电网广域测量系统(wide-area management system， WAMS)的发展，电网形成了具有时空特性的高维海量运行数据。传统的电网暂态分析采用物理模型，用严格的数学公式关联维度之间数据，这种模型不能充分利用海量电网运行数据，造成资源浪费。从数据驱动的角度，首先分析 WAMS 数据的应用情况，考虑电网运行数据特点建立数据模型。然后利用随机矩阵理论(random matrix theory， RMT) 建立平均谱半径(mean spectral radius， MSR)评价指标，从整体上分析不同扰动对电网的影响。在整体分析电网运行状态的基础上，结合随机矩阵理论和时间序列分析(time series analysis， TES)建立量化评价指标，实现对扰动的影响程度分析和影响范围评估。(Power System Transient Stability Analysis Based on Random Matrix Theory)

这里主要对LMS算法及一些改进的LMS算法（NLMS算法、变步长LMS算法、变换域LMS算法）之间的不同点进行了比较，在传统的LMS算法的基础上发展了LMS算法的应用。另一方面又从RLS算法的分析中对其与LMS算法的不同特性进行了比较，很值得研究！(The key players here and some of the LMS algorithm is an improved LMS algorithm (NLMS algorithm, variable step size LMS algorithm, transform domain LMS algorithm) the differences between the points of comparison, in the traditional LMS algorithm is developed on the basis of the LMS algorithm applications. On the other hand and from the analysis of RLS algorithm and LMS algorithm for its different characteristics were compared, it is worth studying!)
