Solution for Unattended Substation System

Background

The underground substation is an important component of the underground power supply system. The safe operation of the substation is related to the safe production and economic operation of the enterprise. Facing the complex geological conditions and harsh working environment underground, the unattended substation is to meet the development needs of the enterprise, which can effectively reduce the personnel number and reduce costs.

Target

In order to improve the automatic control level of the whole mine, improve labor productivity, monitor the production equipment, it should take corresponding technical measures to monitor electrical equipment and system parameters such as current, voltage, power, etc., as well as the operating status, forecast and monitor breakdown signals which would be sent to the control room through network.

System composition

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.

System effect

Unattended high and low voltage distribution rooms;

Automatic data collection;

Remote power stop/start, reduce the labor intensity of personnel.
