Industry Background

Solution Overview

The electrical intelligent O&M solution for coal mining enterprises consists of an upper-level system platform, relay protection devices, intelligent monitoring terminals, and power quality monitoring devices. It achieves real-time data collection, monitoring, display, and intelligent analysis of all electrical operation information, focusing on solving issues such as preventing over-tripping, accident prevention, improving power quality, and eliminating electrical safety hazards. The solution aims to ensure "reliable power supply, safe electricity use, intelligent O&M, and efficient management" within coal mining enterprises.

Solution Advantages

Intelligent O&M model

Intelligent O&M model

By integrating systems and coordinating equipment, using centralized control and big data analysis, the system provides intelligent decision-making support for electrical O&M, eliminating accidents at an early stage.

Predictive equipment maintenance

Predictive equipment maintenance

Historical data analysis and future trend prediction shift equipment maintenance from "fault repair+scheduled maintenance" to "predictive maintenance," improving work efficiency and reducing O&M costs.

Fast non-overreaching protection across the entire network

Fast non-overreaching protection across the entire network

GOOSE technology enables intelligent communication between protection devices, resolving the conflict between relay protection speed and selectivity, achieving fast selective protection within the power supply area.

Orderly management of power quality

Orderly management of power quality

The system enables real-time leakage warnings, online monitoring and analysis of power quality, harmonic detection, and coordinated control, effectively eliminating electrical safety hazards and improving regional power supply quality.

Comprehensive Automation Solution for Coal Mines

Comprehensive Automation Solution for Coal Mines

The comprehensive coal mine automation system consists of surface monitoring substations, underground general monitoring substations, underground explosion-proof monitoring substations, and protection control devices. It uses MMS and GOOSE network-sharing technology to enable real-time transmission of four-remote signals and protection interlock signals through a shared fiber optic dual-ring network between the surface and underground. The protection control device is embedded with GOOSE technology, configuring a GOOSE signal interlock relationship between upper and lower-level protection. Faults in the lower level block adjacent upper levels, forming a fast-moving "surface + underground" high-voltage power supply system.
