The distribution network has characteristics different from the transmission system. Distribution networks are commonly 1. three-phase unbalanced 2. radial with sometimes weakly meshed topology 3. with high resistance to reactance (r/x) rations here, an equivalent current injection method is used in rectangular coordinates to analyse the given radial distribution system. The FDLF method uses the NR-algorithm, with a constant Jacobian matrix. This matrix is further decoupled into two identical sub-Jacobian matrices.

计算一个方柱的散射的波形，并求其RCS。方柱的网格总数是N=500个，时间步为1200步。网格尺寸为lamda/18,时间间隔是ddx/2*c，c为光速。脉冲源位于中心。方柱边长为7*lamda。并与相同尺度的球的散射场进行对比(Calculate the scattered waveform of a square column and find its RCS. The total number of grids of the square column is N=500 and the time step is 1200 steps. The grid size is lamda/18, the time interval is ddx/2*c, and c is the speed of light. The pulse source is at the center. The side of the square column is 7*lamda. And compare the scattering field of the ball of the same scale)
