Design And Application Of Coal Mine Power Network Automatic Control System

Transformer substation as the important link of coal power supply system is grid major monitoring point.Transformer substation automatic control rely on the current rapid development of industrial control network, computer hardware and software technologies. It makes control, protection, measurement, accident records, fault recording, scheduling and other functions in one system platform, completing remote control, telemetry, remote adjustment, remote signaling and realizing transformer substation automatic control.This article comes from Baoji Qinyuan Meiye Company substation reconstruction project, introducing the current states of mine transformer substation system. With analyzing and comparing the coal comprehensive information network, we propose that industrial ethernet is the best platform for coal comprehensive information transmission. With analyzing of the SCADA system functional requirements, we select IFiX as the transformer substation automation system HMI / SCASA solution, and introducing the OPC technology and focuses on the automation system functions to achieve.At present the automatic control system has been running, and meet the needs of Qinyuan Meiye Company substation automation control.
