无人值班变电所监控系统一般是多个厂站端(变电所)和一个主站端(调度室)组成。厂站端和主站端进行数据通信,厂站端把微机采集到的遥测量、遥信量和电能量准确实时地通过串行通信口送到主站端,主站端也可把遥调、遥控等命令通过串行通信下发到某个厂站端。厂站端微机的稳定运行是整个微机监控网稳定运行的基础。
Unmanned substation monitoring system is generally more than one plant site (substation) and a master site (dispatch room). The station side and the main station side for data communication, the station side of the computer to the telemetry collected telemetry, telemetry and electrical energy accurate real-time through the serial communication port to the master station side, the master side can also be remote , Remote control and other orders sent to a plant through the serial communication terminal. The stable operation of the station computer is the basis of stable operation of the entire computer monitoring network.
