5节点的电力系统潮流计算，建立了发电机、变压器、输电线路和负荷模块，使用典型参数计算得到的电压、相位、有功和无功显示清晰，便于分析和设计。(The node power flow calculation, generators, transformers, transmission lines and load module, calculated using the typical parameters voltage, phase, active and reactive clear, to facilitate the analysis and design.)

该源代码是模式识别课程作业。通过K平均算法实现聚类的目的。效果比较好。另外本人还设计了等高线法，用于聚类，思想较好，效果一般，但是值得参考。(This code is a Pattern Recognition homework. It use Kmeans to clustering, and get a good result. It s good for a reference.)

输入信号五个基于瞬时信息的特征：零中心归一化瞬时幅度功率谱密度的最大值,零中心归一化瞬时幅度绝对值的标准偏差，零中心非弱信号段瞬时相位非线性分量绝对值标准偏差，零中心非弱信号段瞬时相位非线性分量标准偏差，零中心归一化的非弱信号段瞬时频率绝对值的标准偏差，得到识别出的信号类别，本例为2PSK, 4PSK, GMSK, OQPSK, pi/4DQSK中的一个，还可以看Art网络的扩展性。(input signal instantaneous information on five characteristics : In the center is one of the instantaneous rate of the power spectral density of the maximum, is a center to the absolute value of the instantaneous rate of the standard deviation, Non-zero weak signal instantaneous phase of the nonlinear component absolute standard deviation, Non-zero weak signal instantaneous phase of the nonlinear component standard deviation, In the center is one of the non-weak signal of the absolute value of the instantaneous frequency standard deviation, the identification of signal type, The cases of two PSK, 4PSK, GMSK, OQPSK, pi/4DQSK of one, Art can be viewed network scalability.)
