Bus Bar-Based Node Admittance Matrix Computer Generation Method

利用计算机进行短路电流计算以节点阻抗矩阵法和节点导纳矩阵法最为常用,目前2种方法所需矩阵的生成方法仍需人工计算输入。基于母线的节点导纳矩阵形成方法,以电力系统主接线为依据,从母线入手进行分析并建立数学模型,结合计算机图形界面以及先进的面向对象程序设计方法,给出了节点导纳矩阵的形成算法,解决了节点导纳矩阵需要人工计算输入的问题,提高了计算效率。

Node impedance matrix method and node admittance matrix method are 2 most popular methods used in short circuit current calculations. However, the generation of required matrices used by these 2 methods still needs manual computation and input. Based on main connection, the bus bar-based node admittance matrix generation method starts from bus bar analysis and mathematic modeling, and combines computer graphic interface and advanced object-oriented program design method to give algorithm of node admittance matrix generation, solving manual input problem and improving efficiency.
