Research on Remote Monitoring System for Leakage Protection of Electric Grid in Underground Mine

摘要

Aimed at realizing remote monitoring system for leakage protection of low-voltage power grid in underground mine in Shanxi Province, intelligent leakage protection device with ZigBee are used underground, and the monitoring software based on LabVIEW is designed on PC, the data of power grid is sent to the mine monitoring center over ground through industrial ring network and published on Web, so as to build a remote monitoring system for leakage protection of low-voltage power grid in coal mine. Industrial experiments results show that the designed system is reliable and stable, which has improved the automation level and information management in coal mine.
