| Abstract: | Aiming at the subspan oscillation phenomenon occuring in multiple split conductor ofEHV and UHV transmission lines,applies the subspan oscillation on-line monitoring system realtime monitoring subspan oscillation and analyzing the oscillation law in 750 kV transmission line, puts forward the spacing stick optimum disposal scheme. The application result shows that thesubspan oscillation on-line monitoring system and the spacing stick optimum disposal scheme solvethe problem of subspan oscillation,effectively elevates the safety operation level of 750 kVtransmisson line. |
