A general graphical user interface based on object - oriented technique , database and visualization in scientific computing has been conducted . we can draw electrical components of the distribution network and fill the components data easily . background programs analyze topology automatically and constitute node admittance matrix , node impedance matrix 它使用图形元件直接绘成系统接线图,在屏幕上输入元件参数,后台程序自动进行网络拓扑分析,然后基于稀疏技术,利用支路扫描法形成节点导纳阵,连续回代法形成节点阻抗阵。
