拉丁超立方抽样，调用方式如下：S=lhs(m,dist,mu,sigma,lowb,upb) m: a scalar,the number of sample points dist: A row with distribution type flags of basic random variables the value of the flag can be 1 (for uniform distribution, 2(for normal distribution), 3(for lognormal) and 4(for extreme type 1). mu: A row vector comprising the mean value of basic random variables. sigma: A row vector with its length equaligng to mu,including the standard deviation of basic random variables. lowb: a row vector with its elements are the lower bound of the sampling interval upb:a row vector with its elements are the upper bounds of the sampling interval dist,mu,sigma,lowb,upb must have the same length. Output argument S: sampling point matrix, of which each row is a sampling point.(code of Latin Hypercube Sampling)

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)
