Abstract
The article presents the remote monitoring systems for operation of high-voltage substations and shovels, designed at the Karaganda State Technical University and introduced at Shubarkol-Komir open pit coal mine. The systems measure power consumption parameters (high-voltage substations and shovels) and controls power consumers and electrical protection. The high-voltage substation monitoring systems transmit data via rf modem, the shovel operation monitoring systems use GPRS modems to transmit data via Internet to a central operator office. In the course of trial operation of the remote monitoring systems, it was succeeded to save power owing to elimination of idle operation of heavy-duty mining machines; moreover, the scope of the continuous control covered power consumption and electric protection at substations and on shovels.
