代码说明:

应用背景由于其较低的计算要求,Haar变换已被主要用于模式识别与图像处理。因此,二维信号和图像处理是哈尔高效应用区域变换由于其小波状结构。在这方面,它通常是最简单的可能的正交小波系统生成从Haar尺度函数与小波。关键技术在数学中, ;Haar小波 ;是一个序列的重新调整的“方形”功能,共同构成一个 ;小波 ;家庭或基础。小波分析是类似于傅里叶分析 ; ;这样可以使目标函数在一个区间将在anorthonormal  表示功能的基础。哈尔序列是现在公认的第一个已知的小波基和广泛使用的教学实例。

More comprehensive mathematical equations of TCSC circuit for any period (including the whole transient processfrom firing the thyristors to a steady state) and for the steady state relating to the voltages and currents of the capacitor,inductor and thyristor components are precisely developed by using Laplace transformation. And the accurate mathematicalrelationship between the fundamental impedance of TCSC and the firing angle of the thyristors is further derived by using Fourier analysis. Via the simulation, having a good understanding of the transience stability on a thyristor controlled series compensation. )
