HVDC-rectifier

说明：  利用PSCAD搭建的单相MMC系统，其中的子模块采用理想电压源与IGBT构成，成功仿真出阶梯波形(PSCAD built using MMC system, single-phase, in which sub-modules form an ideal voltage source with IGBT, successful simulation of the step waveform)

铺画列车运行图，可以参考一下如何画线等语句(plot train diagram)

可将.txt数据转化为grd数据，用于grads画站点图(.txt data can be converted to GRD data for grads drawing site map.)

CAD数字批量加减，适用相对高程、绝对高程加减同样数字，便于CAD图件修改(CAD digital batch addition and subtraction, suitable for relative elevation, absolute elevation, add and subtract the same number, convenient for CAD map modification)

说明：  一个绘制Voronoi图和Delauany三角剖分的程序，并且给出了求凸包的算法。该程序可以演示如何进行三角剖分，帮助你理解整个剖分过程。(a Voronoi diagram mapping and triangulation Delauany procedures, and is seeking a convex hull algorithms. The procedure can demonstrate how triangulation, and help you understand the subdivision process.)

使用matlab编写的根据圆心坐标画圆，且填充颜色(Using Matlab prepared according to the center coordinates of the circle, and fill color)

用于拟合椭圆的函数，支持对于多个离散数据点的椭圆曲线方程计算(new function)

DDA算法画直线，可以实现在网格下逐点画直线。(DDA algorithm for drawing straight lines, can be achieved in a grid-by drawing straight line.)

pscad 中除了自带实例外的例子,包括IEEE34，传输线路故障，变电站(pscad instance, in addition to its own outside of the examples, including IEEE34, transmission line fault, substations)

说明：  DDA、Bresenham、MidBresenham画直线算法(DDA,BresenhamLine,MidBresenhamLine)
