求一潮流计算正确程序
 

可以输入节点数，支路数，平衡母点节点号，误差精度，以及支路参数和节点参数
我也只找了个程序，运行出错
错误如下。Warning: Matrix is singular to working precision.
Warning: Matrix is singular to working precision.
--------------------------------------------------------------------------------
各节点电压U为（节点从小到大排列）:
1.0500 NaN + NaNi NaN + NaNi NaN + NaNi 1.0500

--------------------------------------------------------------------------------
各节点电压相角为（节点从小到大排列）:
0 NaN NaN NaN 0

--------------------------------------------------------------------------------
按公式计算全部线路功率，结果如下:
1.0000 2.0000 NaN + NaNi

2.0000 3.0000 NaN + NaNi

2.0000 4.0000 NaN + NaNi

3.0000 4.0000 NaN + NaNi

5.0000 3.0000 NaN + NaNi

2.0000 1.0000 NaN + NaNi

3.0000 2.0000 NaN + NaNi

4.0000 2.0000 NaN + NaNi

4.0000 3.0000 NaN + NaNi

3.0000 5.0000 NaN + NaNi

--------------------------------------------------------------------------------
各条支路的功率损耗DS为(顺序同您输入B1时一样):
NaN + NaNi

NaN + NaNi

NaN + NaNi

NaN + NaNi

NaN + NaNi

平衡节点的功率:
NaN + NaNi
