Heisenberg2333

A single-phase (uncoupled) branch connects two terminal nodes that are the same.  This makes no physical or
engineering sense since such a branch can not affect the rest of the network,  and the rest of the network can not affect it.  The
last-read data card defines the offending branch.  Assuming fixed-format, the BUS1 name of columns 3-8 equals the BUS2 name to
columns 9-14.                 这是我ATP运行后的错误，求大神指导这个是什么意思？怎样解决啊

是母线名重复了吗。
