PSCAD风机（异步机）+SVC无功补偿模型(PSCAD wind SVC)

采用幅相控制的高压直流输电HVDC的PSCAD仿真模型(PSCAD simulation model of HVDC Using amplitude and phase control)

本程序是计算机图形学课程设计的程序，包含用各种算法绘制直线、圆、曲线，填充，剪裁等，有助于计算机图形学的学习与实践。(This procedure is a computer graphics curriculum design process, including the use of various algorithms to draw lines, circles, curves, filling, cutting, etc., help to learn and practice of computer graphics.)

这是一个很不错的 4-D 多面体绘图程序。内附详细说明(This is a very good 4-D polyhedron mapping procedures. Containing a detailed description)

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)

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

三角形判断问题。可用于黑盒测试用例设计。(Triangle judgment. Can be used for black-box test case design.)

DDA直线绘制程序实现，可以是任意的直线。(DDA line drawing program, a straight line can be arbitrary.)

已知型值点反求控制点，最后获得B样条曲线(Data points are known to reverse the control point, and finally obtain B-spline curve)

国外高手写的可以读写dxf格式信息。值得收藏(Foreign experts to write the information can be read dxf format. Worth collecting)
