EHV transmission lines usually adopt one-shot auto-reclosing scheme.In this paper
the favorable effects of properly designed two-shot auto-reclosing scheme for some EHV transmission lines are analyzed
and the design idea of a two-shot auto-reclosing device for 500 kV transmission lines is introduced.Furthermore
the implementation method of adding second-shot auto-reclosing function to existing protection devices is discussed.Analysis shows that the stability of the power system can be improved by applying two 0 shot auto-reclosing scheme to some EHV transmission lines.The two-shot auto-reclosing devices have been applied to the North China Power Grid and have achieved good operation effect.
