Abstract

Abstract

The paper introduced working principle of power balance technology in multi-motor driving system of coal mine and gave application of the technology in belt conveying system of a coal mine. The application showed that using power balance technology in belt conveying system can make currents of master motor and slave motor change with loads synchronously, so as to reduce ratio of fault shutdown caused by power unbalance of frequency converter.
