用matlab中的simulink搭建statcom模块，已经通过测试(use matlab to build the statcom model)

：MATLAB 是目前在国际上被广泛接受和使用的科学与工程计算软件。虽 然 Cleve Moler教授开发它的初衷是为了更简单、更快捷地解决矩阵运算，但 MATLAB 现 在的发展已经使其成为一种集数值运算、符号运算、数据可视化、图形界面设计、程序设 计、仿真等多种功能于一体的集成软件。 (MATLAB is now widely accepted and used in the international science and engineering calculation software. Although However, Professor Cleve Moler its original intention was to develop a simpler, more efficient solution to the matrix operation, but now MATLAB Has been making in the development of a set of numerical computation, symbolic computation, data visualization, graphical interface design, program design Meter, simulation and other functions in one integrated software)
