常见的潮流程序主要采用直角坐标来进行，本程序采用极坐标对简单输电网系统潮流进行计算(Common trend of the procedure used mainly for rectangular coordinates, polar coordinates, the program uses a simple grid system to calculate the trend)

相参脉冲串复调制信号，关于小波的matlab复合分析，比较了软阈值，硬阈值及当今各种阈值计算方法。( Complex modulation coherent pulse train signal, Matlab wavelet analysis on complex, Comparison of soft threshold and hard threshold and today various threshold calculation method.)

说明：  潮流计算是电力学名词，指在给定电力系统网络拓扑、元件参数和发电、负荷参量条件下，计算有功功率、无功功率及电压在电力网中的分布。潮流计算是根据给定的电网结构、参数和发电机、负荷等元件的运行条件，确定电力系统各部分稳态运行状态参数的计算。通常给定的运行条件有系统中各电源和负荷点的功率、枢纽点电压、平衡点的电压和相位角。待求的运行状态参量包括电网各母线节点的电压幅值和相角，以及各支路的功率分布、网络的功率损耗等。(Power flow calculation is a term of power science. It refers to the calculation of the distribution of active power, reactive power and voltage in power network under given network topology, component parameters and generation and load parameters. Power flow calculation is based on the given grid structure, parameters and operation conditions of generator, load and other components to determine the steady-state operation parameters of each part of the power system. Usually, the given operating conditions include the power of each power source and load point, junction voltage, balance point voltage and phase angle. The parameters to be determined include the voltage amplitude and phase angle of each bus node, the power distribution of each branch and the power loss of the network.)

求解瞬时频率函数，一般在matlab时频分析中使用(Solve the instantaneous frequency function, usually in the time-frequency analysis using matlab)
