for PSCAD softwear it can be very easy and coming soon challenger in this soft

对角度跟踪并给出详细的跟踪结果，比较不同情况下的运行效率，绘制跟踪误差曲线，直接给出曲线图，可以直接运行.(For pure Angle tracking and give detailed tracking results, draw tracking error curve, compare different situations efficiency, direct given curve, can be directly run)

说明：  绘图工具visio使用教程，仅适用于数据流图(Use drawing tools visio tutorial applies only to data flow diagram)

PSCAD的环境下的仿真模型，包含光伏，风机燃气轮机部分对与初学者有很大的借鉴作用(PSCAD environment simulation model, including photovoltaic, wind turbine and gas turbine part of a great reference for beginners)

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)

图形学上机实验，用三种算法画线。包括Bresenham画线算法、中点画线和数值微分画线算法(Graphics on an experiment with three algorithms draw the line. Bresenham line algorithm, the dotted line and numerical differential line drawing algorithm)

说明：  根据光伏电池相关的理论和数学模型，利用PSIM建立一种简单并且准确的光伏阵列模型。同时，在此模型的基础上建立具有MPPT功能的直流变换器仿真模型。比较不同环境下的输出曲线的仿真结果以及实验数据。仿真结果和实验数据吻合，证明了此模型的适用性和准确性(Photovoltaic cells in accordance with the relevant theoretical and mathematical models, using PSIM to establish a simple and accurate model of the photovoltaic array. At the same time, in this model based on function with MPPT DC-DC converter simulation model. Compared under different circumstances the output curve of the simulation results and experimental data. The simulation results and experimental data proved the applicability of this model and accuracy)

手动绘制点，自动生成样条曲线，可以拖动修改点来修改样条曲线(Manually plotting points, automatically generated spline curves, you can drag the modified point to modify the spline)

实现绘制5个圆形组成的图案，继承Jpanel类的DrawPanel内部类，并重写paint()方法。(Plotting of five circular pattern composed of inherited Jpanel class DrawPanel inner class, and override paint () method.)

说明：  用VB编写的简易的绘图程序，用来绘制直线圆和矩形，可以选择绘图颜色和画笔粗细。(VB, easy to use drawing program, circles and rectangles to draw a straight line, you can select the drawing pen color and thickness.)
