Reform of Integrated Automation of 35/6 kV Coal Mine Substatio

Taking Gequan Coal Mine as example, the paper proposed an improved scheme of automation technology of 35/6 kV coal mine substation. Through reform of integrated automation, the substation realizes functions of relay protection and control, remote operation, metering, fault recording, data processing and five anti-lock operation, on-line monitoring, which meets with need for later post-expansion and reform of substation line.
