提出了三种实现变电站中高压母线备自投和中、低压母线备自投配合的方式。其一采用延时定值保证高压母线备自投先于低压母线备自投动作;其二采用开关量保证高压母线备自投动作过程中低压母线备自投不动作;其三在备自投全部动作过程中都对备供电源电压进行检查。

The thesis provides three ways to cooperate automatic-switching-devices on both higher and lower voltage buses.The first is to set proper delays for the two devices so that the device on lower voltage bus operates later than the one on higher voltage bus;the second is to inform the device on lower voltage bus whether the device on higher voltage bus is in operation;the third is to check voltage of backup on every step of operation.
