matlab的psat软件用于潮流计算，连续潮流计算，小扰动分析，分岔分析等等，方便实用(The psat matlab software for flow calculation, continuous flow calculation, the small perturbation analysis, bifurcation analysis, etc., convenient and practical)

说明：  电力系统拓扑分析、孤岛数，关联矩阵法把主接线的节点和母线的每一进出线连接点作为拓扑图的节 点，把开关元件作为拓扑图的支路，建立节点．支路关联矩阵表示电网的基本拓 扑结构。然后定义矩阵“与．或’’乘法运算，利用连通性的传递性质实现对电力 网络结构的辨识。(In the incidence matrix method, the node of the main connection and the connection point of each incoming and outgoing line of the bus are taken as the node of the topology diagram, and the switching element is taken as the branch of the topology diagram to establish the node.The branch correlation matrix represents the basic topology structure of the power grid)

说明：  利用白噪声测量系统动态响应.需要自己建立一个simulink model.(use white noise to measure dynamics of system.)

NR法潮流计算程序，内附详细说明，希望对大家有帮助(NR power flow matlab program, hope it could help)

matlab编写的伪随机序列发生器，包括小m序列、大M序列，gold序列(pseudo-random sequence generator matlab prepared, including a small m sequence, M sequences, gold sequences)

IIR滤波器设计 设计一个巴特沃思低通滤波器，其技术指标为：3dB带宽为，阻带截止频率为，阻带衰减大于30dB，采样间隔T=10us。(IIR filter design to design a Butterworth low-pass filter, its technical indicators: 3dB bandwidth, stopband cut-off frequency, stop-band attenuation greater than 30dB, sampling interval T = 10us.)

对给定的含噪脉冲信号进行相关检测。检测结果用1、0表示。要求从文本文件中读入数据，分析滤波前后的信号统计特征：包括均值、方差、自相关和功率谱。设计参考信号，进行相关处理和检测；画出原始数据的曲线以及相关结果的曲线(For a given pulse signal associated with noise detection. Test results with 1,0 said. Asked to read from a text file into the data, analyze the demographic characteristics of the signal after filtering include: mean, variance, autocorrelation and power spectrum. Design reference signal, the associated processing and testing draw the curve of the original data and the associated results of the curve)
