Abstract：In Electric power production, anti-misoperation lockout and related organization management should be used, in order to prevent the safety of power grid production.The existing anti-misoperation lockout system cannot lock the break’s switching on which is in hot standby state,while the line earth-switch of another side is closing,which means itcannot prevent the false operation between substations.Through the analysis of typical 500kV line residual voltage while breaks between line in different states,which belong to 3/2 wiring,this paper provides one rule of preventing false operation between substations by using line residual voltage,and discusses the possibility of improving of the exist automation and monitor device and anti-misoperation lockout system.
