Coal Mine Electric Power Monitoring System

Product Description

Coal mine electric power monitoring system

System introduction

Coal mine electric power monitoring system is suitable for coal mine power supply system. Through collecting real-time data and remote control, coal mine underground power supply automation is realized (project of the Ministry of Science and Technology). Power monitoring and control system using mine power monitoring substation substation of underground mining, underground central substation, the function of substation, 35 KV substation (11KV) and ground, 6 KV, 10 KV substation, tested the step-down station monitoring on the ground, with well up and down on the remote control power switch and electrical equipment/electricity, telemetry, remote communication, remote setting, commonly known as five away, and other functions, so that the underground substation is unattended or few people on-duty, reducing power supply accidents, shortening fault handling time, rationally deploying equipment operation, improving equipment operating efficiency, and realizing remote monitoring of power systems.

The configuration of mine electric power dispatching command system with Ethernet ring network and other networking modes can meet the high, medium and low-end needs of different users.
The coal mine power monitoring system monitors the power parameters of the output line voltage, current, active power, reactive power, power factor, electrical degree, system frequency, fault alarm, and switch opening/closing state of the substation, and is powered by electricity. The monitoring substation performs analysis and processing, and uploads the monitoring data to the ground management center for signal display, storage, and network distribution. The system meets the needs of power safety monitoring and monitoring within the power range.

System functions

• The system can real-time monitor output voltage, current, active power, reactive power, power factors, system frequency, fault alarm, switch opening/breaking state and other power parameters of the substation, and upload the test data to the ground management center for signal display, storage, and network publishing.
• The supervisory computer in centralized control center can online modify the integrated alarm of underground switch or action tuning parameters and some other control signals. 
• The system can display malfunctions like overcurrent, phase failure, undervoltage, overload and others, and break the brake in time to protect the normal operation of equipment and power grid to avoid accidents.
• The monitoring host of system adopts backup mode, to ensure reliable operation.
• Can remote test and record the underground explosion-proof low-voltage integrated protection device and automatically record the manual leakage test through the supervisory computer of power supply management department on the ground.
• Classified assessment and management of electricity.
• Can remote monitor the environment and equipment of underground substation through video, and can be embedded display videos and images, linkage display illegal personnel entry and fire alarm, and record and inquiry images through digital hard disk on the monitoring host

System characteristics

• Through the data conversion, sorting and mining of the monitoring system, the system carries out comprehensive dynamic analysis and data management of the production situation.
• To free operators from the complicated manual and transactional work in order to engage in other valuable work.
• To achieve centralized management of the network, monitor and deal with all kinds of equipment on the network, and provide guarantee for the normal operation of the network.
• It can effectively realize the functions of production, safety management and comprehensive query, and make it a comprehensive system engineering.
• The system is safe, advanced and reliable to meet the requirements of production and management.
