用遥控方法实现远动遥测处理板的复归

Remote reset of measuring management board

针对无人值班变电所远动设备运行中所出现的分站系统遥测处理板频繁死锁现象,借鉴远动装置遥控复归常规及微机保护信号的方法,在现有远动设备的基础上,对设备做少许改造,利用遥控方法实现对遥测处理板的远方遥控复归。给出了改造后的复位电路及方法。

The measuring management board of a remote automation system in an unattended substation may go dead in operation. Learning the remote reset methods from remote terminal unit and microcomputer protection,the reset circuit of the measuring management board is improved with little reconstruction to allow the board reset remotely. The reconstructed reset circuit and resetting procedure are presented.
