droop

WPF 鼠标拖拽功能，自定义拖拽的跟随图形，不再是一个虚线的系统的小标志，而是具体所拖拽的对象的图形，比如拖一个button，后面跟随的就是一个button的形状。(WPF mouse drag and drop, drag the following custom graphics, broken system is no longer a small sign, but concrete by dragging a graphical object, such as dragging a button, is followed by the shape of a button.)

PSCAD Simulation for Lines

自己在PSCAD中搭建的高压直流输电逆变侧的模块，本模块使用了定电流策略，比较容易上手，适合初学者学习(PSCAD built himself in the side of the HVDC inverter module, the module uses a constant current strategy, relatively easy to use, suitable for beginners to learn)

GDI source code. You can learn drawing in first

计算机图形学，mfc实现二维图形的基本几何变换，如平移、旋转、缩放、对称、错切变换(Computer graphics, mfc achieve the basic two-dimensional graphics geometric transformations, such as translation, rotation, scaling, symmetry, shear transformation)

集中介绍了HDC,CDC,CClientDC,CPaintDC,CWindowDC的使用方法和区别，绘图显示效果，区分窗口客户区。(Focus on the HDC, CDC, CClientDC, CPaintDC, CWindowDC to use and distinction, graphics effects, to distinguish the window client area.)

曲线坐标提取，需导入图片，进行手动选取，还比较方便(Curvilinear coordinates extraction)

自己利用ＰＳＣＡＤ搭建的滞环比较变换器，成功的仿真出正弦波形。(Their use of hysteresis built PSCAD converter, a successful simulation of the sine wave.)

说明：  电网pq控制，pscad，有功功率与无功功率可控(failed to translate)

说明：  vc ++ 6.0 实现的各种统计图，线图，饼图，直方图(Charts including pie，line and bar chart)
