Three Phase load with Externally controlled Variable Source with PSCAD

unicet和netdraw使用手册，能够较好的学习这两种软件，用于网络绘图(unicet, and netdraw use the manual, better able to learn both software for network drawing)

系统辨识作业 考虑如下模型 z(k)-1.5z(k-1)+0.7z(k-2)=u(k-1)+0.5u(k-2)+v(k) 其中v(k)是均值为0，方差为1的白噪声。根据模型生成数据，采用递推最小二乘法对模型参数进行辨识，要求绘出各参数随时间的变化曲线。 ("System identification" computer test 。Consider the following model Z (k) to 1.5 of z (k- 1)+ 0.7 z (k- 2) = u (k- 1)+ 0.5 u (k- 2)+ v (k) The v (k) is the mean to 0, the white noise variance 1. Generate data according to the model, the recursive least squares method is adopted to model parameters are identified, draw the parameters changing with time curve. )

用python实现复杂网络的度分布绘图，本程序以wyp同志的论文数据为例。(Degree with a python distribution mapping of complex networks, the procedures to wyp comrades paper data as an example.)

精彩原代码，适合初学者(brilliant original code for beginners!)

说明：  用matlab实现画圆，采用bresenham的画圆方法，内含代码还有文档(Draw a circle with matlab implementation, using bresenham the Circle method, there is a document containing the code)

自由曲线图表、柱状图、饼图的实现与转换，基于一套简单的图形类库（源代码在内）。(free curve charts, column, pie and the realization of conversion, based on a simple set of graphics libraries (including source code).)

一款用vc++编写的画图软件，本软件提供了画一些基本图形的功能，还有将图形进行填充。(vc with one prepared by the drawing software, the software provides a graphic pictures of some of the basic functions, there will be graphics for filling.)

CAD画施工图图解教程，简单易懂,可以快速学会使用。(CAD painting construction drawing graphic tutorials, simple and understandable.)
