Substation is set up at each level with a collection control station, which collects various data from the comprehensive protection system of the central substation and the multi- functional monitoring device system installed in the substation, and transmits the electrical data in distribution circuits such as current, voltage, power, etc. to the control system. Communications network Collect data from comprehensive insurance system and multi- function meter through RS485 or Ethernet Acquisition control station A control station is set up in the substation at each level, which can process the collected information, and can remotely stop and transmit power through the control station. Monitor host A monitoring host is placed in the surface control room to display real-time data of substations underground, which is used to set parameters, display alarms, remotely control power transmission, etc., and create production electricity reports.Unattended high and low voltage distribution rooms; Automatic data collection; Remote power stop/start, reduce the labor intensity of personnel.
