Industry Background

Solution Overview

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.

Solution Advantages

Fast non-overreaching protection across the entire network

Fast non-overreaching protection across the entire network

GOOSE technology enables intelligent communication between protection devices, eliminating the need for strict coordination of settings and timing, resolving the conflict between relay protection speed and selectivity, and achieving fast selective protection across the entire grid.

Adaptive operation

Adaptive operation

The adaptive system operation method features a clear network structure and flexible configuration, unaffected by its position within the power supply system. It is easy to expand and maintain, making it suitable for various types of radiating power supply networks.

Breaker failure protection

Breaker failure protection

The solution achieves breaker failure protection through GOOSE interlocking and network interoperability, while also reducing the response time of backup protection.

Protection function does not rely solely on the network

Protection function does not rely solely on the network

The system uses a layered, distributed structure. Protection and control functions are distributed in each bay layer unit, ensuring that basic protection functions are not affected by network interruptions.
