| Abstract: | In order to solve the problem of zero sequence circular current in the same tower doublecircuit transmission lines in Ningxia Power Grid, adopts the whole digital real time simulation methodto make simulation analysis. The results show that the size of zero sequence circular current is relatedto the layout mode of the phase sequence inside the same tower double circuit untransposedtransmission lines, through changing phase layout can reduce the amplitude value of zero sequence cir?cular current. |
