Abstract:110kV power grid for the online contact one end of the blackout, the original substation devices prepared from the vote since the vote can not achieve the distance function, leading to some of 110kV substation and one end of the 220kV substation site-wide blackout. Study on a use of existing fiber-optic communication channel information transmission operation, fault information and jump Reclosing command standby power mode of the program since the vote. Prepared through the transformation of the original cast from the device, increasing the number of voting logic program, the installation of fiber optic communications modules, implementation of the interface with the fiber-optic network. HandanCity in HebeiProvince by the 110kV grid in the application and implementation, good implementation of the tandem distance standby power grid since the vote.
