Transient-Recovery-Voltage-(TRV)

MATLAB下绘制三维极坐标图，输入极径和角度范围，还可以选择画图的种类，也可以画等高线图(Draw three-dimensional polar plot using MATLAB.)

说明：  B样条曲线和三次B样条插值的相关知识不完全总结(B-spline curves and three B-spline interpolation of the relevant knowledge does not fully sum up)

scatterbar就是画出三维散点柱状图，并且可以调整柱子的大小和颜色渐变，比原函数bar3更方便，更好用。(scatterbar is to draw three-dimensional scatter histogram, and can adjust the size and color gradients pillars, and more convenient than the original function bar3, easier to use)

generating the sine wave without using the command with using cordic algorithm

用于绘制任意阶次的bezier曲线，只需要输入节点坐标即可(The Bezier curve for drawing any order)

说明：  利用matlab绘制ROC曲线图，需要的同学们可以自行下载。(ROC curve drawing with matlab,students who need it can download it by themselves.)

说明：  三次样条插值 MATLAB编程 可直接会出图像并输出样条函数(Cubic spline interpolation can be directly MATLAB programming will be the image and the output spline function)

基于PSCAD的风机建模与仿真简单示例，包括风源、风机、发电机参数的设定。(Modeling and Simulation of Wind Turbine based on PSCAD)

自己在PSCAD中搭建的PLL，用的是分立元件搭建的，有助于自己学习以及编程实现，已经与自带的PLL进行对比，验证了正确性(PSCAD built himself in the PLL, using discrete components built to help you learn and programming has been compared with the built-in PLL, verify the correctness)

2次B样条曲线和3次B样条曲线的matlab绘制，适用于初学者(Two B spline curve and cubic b-spline curve realization code, debugging through matlab, apply for beginners )
